INTRODUCTION

Marinfloc is committed to working towards global goals, and we want to inspire and involve others to join in.
In 2015, world leaders agreed to 17 Global Goals. These goals have the power to create a better world by 2030, by ending poverty, fighting inequality, and addressing the urgency of climate change. Guided by the goals, it is now up to all of us, governments, businesses, civil society, and the general public to work together to build a better future for everyone.

7 Affordable and clean energy – Our current reliance on fossil fuels is unsustainable and harmful to the environment, mandating a shift in how we create and consume energy.
On our site in Varekil, Marinfloc has placed solar panels on our new office building. With a total capacity of 34 kW and 950 standard solar hours per year in Varekil, we will create about 31.000 kWh per year.
We export surplus energy to the grid when we don’t consume it ourselves. Because sunshine is sparse in Sweden during the winter, solar panels will not be sufficient, but the power we buy comes from approved renewable sources.
14 Life below water – Conserve and sustainably use the oceans, seas, and marine resources for sustainable development. Healthy oceans and seas are essential to our existence.
They cover 70 percent of our planet, and we rely on them for food, energy, and water. Yet, we have managed to do tremendous damage to these precious resources.
We must protect them by eliminating pollution and overfishing and immediately start to responsibly manage and protect all marine life around the world.
This goal goes hand in hand with our vision of “a clean sea”. Producing water treatment systems prevents harmful substances from polluting the sea.
12 Responsible consumption and production – Our planet has provided us with an abundance of natural resources. Yet, we have not utilized them responsibly and currently consume far beyond what our planet can provide.
In addition to the work we do today, Marinfloc will continue new options to use and produce in sustainable ways that will reverse the harm that we have inflicted on the planet.
We are and will continue to focus on greener materials and transportation, as well as less travel, as we try to reduce our carbon footprint.
15 Life on land – A flourishing life on land is the foundation for our life on this planet. We are all part of the planet’s ecosystem and we have caused severe damage to it through deforestation, loss of natural habitats, and land degradation.
Marinfloc has constructed a meadow in the northwest corner of our property in Varekil instead of cutting it as a lawn. The first year has been dominated by various grass species, but several flowers have bloomed – attracting butterflies, bees, and other insects.
The meadow is a long-term project and is cut by a mower beam and scythe, and the vegetation is removed to avoid fertilization. This will increase the number of flowers eventually.

Improving by Removing

The maritime industry is ready to speed up its shift to greener shipping. This is a positive development, and the fact that shipowners are lobbying for faster technological and regulatory advancement at a quicker pace than the IMO is historical.
More stringent emissions regulations usually add more equipment onboard. However, the amount of equipment that can be added to the engine room and the amount of time that the crew has remaining for new operations are both limited.
Combining treatment units for different waste streams is one way to overcome this challenge, and even though a combined system for bilge, black, and grey water is technically possible, there are too few common denominators for effluent water parameters.
For separate waste streams with identical effluent discharge requirements, it is a whole new ballgame.
The oil content (below 15 ppm) is the only regulated parameter for the discharge of either MEPC.307(73) regulated EGR bleed-off water or MEPC.107(49) regulated bilge water.
Therefore, it made perfect sense to develop a treatment system that can treat both.
The Marinfloc, class-approved, combined EGR bleed-off water and bilge water treatment system is the first solution ever to treat waste streams belonging to various MARPOL Annexes.
By integrating the Whitebox® and segregation valves, the requirement not to mix MARPOL Annexes I and VI waste, and the recording of discharge data in the oil record book and the EGR record book, are fulfilled.

EGR Bleed-off Water Treatment

NOX Reduction Technologies

Air emission regulations are driving the development of primary engine technologies and secondary exhaust emissions reduction systems.
The reduction of NOX emissions at the source and the treatment of exhaust gas after combustion are the most common technologies utilized to meet the IMO Tier III standard.
NOX can be reduced by Selective Catalytic Reduction (SCR) or Exhaust Gas recirculation (EGR).
SCR uses urea that reacts onto a catalyst and EGR reduces NOX by redirecting exhaust to the engine air intake.

Exhaust Gas Recirculation

Exhaust gas recirculation (EGR) is a process that redirects a portion of the exhaust gases (roughly 30–40%) to the engine’s intake side and then back into the cylinders.
The recirculated exhaust gases reduce the amount of oxygen (O2) in the incoming air while increasing the amount of carbon dioxide (CO2).
The peak combustion temperature drops dramatically as a result of the lower O2 content and higher specific heat from CO2 in the combustion air, resulting in lower NOX formation.
To prevent corrosion of the combustion chamber components and the EGR system components, the recirculated exhaust gases must be cleaned and cooled before being re-introduced into the engine’s air inlet system.
The degree of cleaning is determined by the sulfur content of the fuel used. The recirculated exhaust gas is cleaned and cooled using fresh water.
The combustion process produces condensate which must be drained from the EGR unit and treated before overboard discharge.

NOx

NOX is a generic term for nitrogen oxides. NOX is generated in the combustion process of a diesel engine and contributes to the formation of smog, acid rain, and eutrophication. NOX is regulated in MARPOL Annex VI, and an engine installed on a newly constructed ship must comply with the Tier III NOX standard when operating in the European and North American Emission Control Areas. NOX can be reduced either by Selective Catalytic Reduction – SCR or Exhaust Gas Recirculation – EGR.

EGR Bleed-off water

Water is used to cool and clean the EGR gas, and the volume will increase due to the condensation of water generated in the combustion process.
The surplus water will overfill or bleed off to an EGR bleed-off tank.
The amount of bleed-off water and level of contamination depends on the engine size, load, and air humidity.
The recirculated water will absorb particles from the exhaust gas, and dissolve as suspended solids in the water and the bleed-off needs to be treated to below 15 ppm and measured by an MEPC.107(49) approved oil content meter before discharge overboard.
Bleed-off water is governed by the IMO Guideline
MEPC.307(73), 2018 Guidelines for the Discharge of Exhaust Gas Recirculation (EGR) Bleed-off Water.

Marinﬂoc EGR Bleed-off Water Treatment System

Flocculation is an ideal treatment technology for EGR bleed-off water. Small particles and oil emulsions from the exhaust gas are bound together and separated instead of blocking filters. The system is developed for low-sulfur, LNG, or methanol two-stroke marine engines. Water from the EGR system bleeds off to an EGR bleed-off water tank. At a preset level, the treatment process starts. A pump feeds the bleed-off water to the CD unit, and the majority of contaminants are separated into a sludge tank in the flocculation process. The water is treated to below 15 ppm and is discharged after oil content analysis by an MEPC.107(49) approved oil content meter.

Key beneﬁts

Flocculation technology. No cartridge filters nor centrifuges are required.
Adjustable to the ship-specific EGR bleed-off water composition
Low energy consumption for low carbon footprints
Can be integrated with the Whitebox® to also treat bilge water
Low operational cost
Stainless steel material
Made in Sweden

Combined EGR and Bilge Water Treatment System

A combined treatment system for EGR bleed-off water and bilge water is a convenient installation to minimize the cost of equipment, installation, and operation related to the discharge of bilge water and EGR bleed-off water.
Bilge water and EGR bleed-off water belong to different MARPOL Annexes and must hence be kept segregated, and there must be separate holding tanks and sludge tanks.
The system segregation valves prohibit the mixing of the two, including the generated sludge from the treatment process.
The class-approved automated switch-over sequence with interlocks is controlled by the system automation. From the control panel, the operator can easily select which waste stream to treat.
The Whitebox® will control and record the system’s vital discharge parameters and segregate the amount of discharged bilge water and EGR bleed-off water for separate record keeping as required.

Process description

The CD unit can take suction from either the EGR bleed-off tank or the Bilgewater holding tank. Three three-way valves connected to a selector switch ensure that the waste streams are not mixed.
The EGR bleed-off water is collected in a bleed-off water drain tank with a soot trap. The tank should be equipped with heating coils to heat the water to 40-55 °C. Alternatively, a heat exchanger is mounted before the treatment unit.
A solid sensor in the tank will detect the solidification of soot. The system must have segregated sludge tanks as per the MARPOL requirements.
The wastewater is treated overboard through a Whitebox® by the CD unit and all vital system data such as tank levels, valve positions, oil content, discharged volume, etc. is recorded and logged in the Whitebox® recorder.

Bilge Water

Not just oil in water

No other waste stream on a ship is as closely linked to million-dollar fines and imprisonment as bilge water (engine room-generated wastewater).
The term “magic pipe” is well-known among marine engineers, and many have seen them in action because they are still commonly used on ships.
We believe that the reason for this isn’t a lack of knowledge or trust, but rather a lack of appropriate tools to handle day-to-day operations.
Bilge water isn’t just limited to oil and water; anything brought into the engine room can end up in it.
This cocktail contains washing chemicals, rust, sewage leaks, boiler water chemicals, lubrication, and hydraulic oil, foaming liquids, CIP fluids, grey water leaks, metals, soot, bacteria, dust, and other contaminants.
This variation creates a most difficult challenge for marine engineers as conventional static separators are only designed to treat bilge water consisting mostly of marine fuel oil and water.
The gap between design and reality leads to inefficiency, which is why the majority of ships violating Annex I regulations can be traced back to simpler types of separators.

Flocculation

Flocculation is a water treatment process in which solids come together to form larger clusters, or flocs, which are then removed from the water.
This process can occur naturally or with the assistance of chemical agents.
It is a common method of wastewater treatment and drinking water purification.
The process of flocculation is chemical in nature. It entails sequentially adding chemicals to the wastewater and allowing tiny solid particles to aggregate into larger particles that can be separated from water.
The treatment of wastewater by flocculation is done in stages.

Dissolved air ﬂotation

Dissolved air flotation (DAF) is a water treatment method that removes suspended particles such as oil or sediments from wastewater or other liquids.
The separation is accomplished by dissolving air under pressure in the water or wastewater and then releasing the air at atmospheric pressure in a flotation tank.
The released air forms tiny bubbles that cling to the suspended matter, causing it to float to the surface where it can be removed.
Solid particles suspended in wastewater are negatively charged. A coagulant, such as aluminum chloride, is added to the wastewater. The negatively charged solid particles suspended in the water are neutralized by the positively charged coagulant molecules.
The neutralization of these particles allows them to flocculate together into a larger particle. A polymer chemical is added to the wastewater once flocs begin to form. Polymers link the flocculant from micro to macro flocculant, increasing the mass of particles clumping together. This chemical also binds the collected mass together, preventing it from dissolving even when the water is slightly agitated.
This technique is widely used in land-based industrial wastewater treatment units for oil refineries, paper mills, general water treatment plants, and other industrial facilities.
Water being fed to the DAF tank is often (but not always) dosed with a flocculant to bind the particles into bigger clusters.

Marinﬂoc Oily Water Separator

Developed to meet onboard conditions

The CD unit is a dissolved air flotation and flocculation unit that treats bilge water to below 5 ppm. The technology enables the treatment of bilge water of various compositions as the operator can adjust the dosage to the current conditions at hand.
It was developed onboard ships not simply to fulfill the MARPOL requirements but to meet onboard conditions.

Key beneﬁts

Flocculation technology: no cartridge filters nor centrifuges are required
Adjustable to the ship’s specific bilge water composition
5 ppm type approved
Low energy consumption for low carbon footprints
Can be integrated with the Whitebox®
Low operational cost

The treatment process

The process can be divided into five stages: Oil separation, Aeration, Flocculation, Flotation, and Filtration.

Oil separation. Free oil floats on water and is separated in the oil descaler by gravity to the sludge tank.
Aeration. Air is dissolved in the water under pressure.
Flocculation. Flocculation chemicals are added and coagulate emulsions, chemicals, and particles to flocs.
Flotation. The dissolved waste from the aeration process is released into the flocs that are lifted to the top of the flotation tank and removed to the sludge tank.
Filtration. The clean water from the flocculation process is filtered to 0-5 ppm before being discharged overboard.
- Capacity range between 0.25 and 5.0 m³ per hour.

TD Pre-treatment

The Marinfloc TD Pre-treatment system is a fully automatic emulsion-breaking bilge water cleaning system based on the technology of flocculation from the Marinfloc Oily Water Separator TD model.
The TD Pre-treatment will remove emulsified contaminants and suspended solids and feed the clean water to the existing Oily Water Separator (OWS) to achieve 15 ppm.
It will also significantly cut your existing filter cost, making the return on investment as little as one year.

Key beneﬁts

Complements the existing OWS to continuously achieve less than 15 ppm
Considerably cuts the current operational costs
No need to update the IOPP-certificate
Plug-and-play installation
No training is needed for the operation
Minimal maintenance and spares
No additional tanks needed
Space efficient

CD Pre-treatment

Just like the TD Pre-treatment, our CD Pre-treatment system is an emulsion-breaking unit to be installed upstream of the existing Oily Water Separator to help it reach the discharge limit.
It is a fully automatic system based on the emulsion-breaking technology of flocculation and dissolved air flotation directly derived from the patented Marinfloc Oily Water Separator CD model.

Key beneﬁts

Supports the existing OWS to continuously achieve less than 15 ppm
Considerably cuts the current operational costs
Can be upgraded to an approved MEPC.107(49) unit
No need to update the IOPP-certificate
Plug-and-play installation
Minimal maintenance and spares
No additional tanks needed
Space efficient
It should be understood that a piece of gravitational filtering equipment cannot be expected to be effective over the complete range of oils that might be carried on board ship, nor can it deal satisfactorily with oil of very high relative density or with a mixture presented to it as an emulsion.
MEPC.60(33)

Compliance

Compliance means obeying the law. Ethics is the intent to observe the spirit of the law, and the expressed intent to do what is right. The effects of unethical behavior on a shipping company and its personnel, both on land and at sea, can be catastrophic.
Million-dollar fines, lengthy probation periods, and costly environmental compliance procedures are a consequence of not being compliant. Magic pipes do unfortunately not belong to the past.
Recent incidents in the United States have highlighted the need for a well-implemented bilge management program as well as adequate environmental compliance programs.
The US regulations with the Whistle blower’s Protection Act, False Statements Act, Sarbanes-Oxley Act of 2002 (obstruction of justice), witness tampering, Act to Prevent Pollution by Ships, and more, enable the Department of Justice to prosecute individuals and shipping companies for violations also committed outside US waters. Prioritizing bilge water compliance is important to protect your crew and the company and has proven to be a smart business decision.
Marinfloc has over 25 years of expertise in solving the challenges associated with bilge water and understands how to limit the risks of noncompliance.

Oil Content Meters

OCMs are used to monitor bilge water oil content, also known as 15 ppm bilge alarm.
High ppm and alarms are frequently blamed on oil content meters. “There is no oil in this water” a disgruntled engineer laboring with the bilge water discharge could say.
ppm stands for part per million and the meters are designed to detect oil content levels at these extremely low concentrations. It’s a popular misperception that water with a 100-ppm oil concentration will have a sheen on the surface.
Emulsified oil leaves no sheen on the water’s surface, and it’s hard to tell how much oil is in a sample by looking at it. Sure, the OCM will alarm for rust and dust at some point, however, the source of the high oil content reading is found upstream.
Operators should address the underlying issue rather than the symptoms. Instead of condemning the meter, operators should accept this situation and consult the OWS manufacturer if the water cannot be treated to meet acceptable levels.

Emulsions

An emulsion is a combination of two liquids that are typically immiscible due to liquid-liquid phase separation.
Already in MEPC.60(33), it was stated that gravimetrical separators could not be expected to clean emulsified bilge water to a satisfactory level.
Still today, a majority of OWS on the market are based on gravimetrical separation and filtration. This has created a discrepancy between products just fulfilling MEPC test standards and real shipboard conditions.
Emulsions cannot be separated gravimetrically, and filters often fail to preserve performance in shipboard conditions beyond the 120 minutes required for MEPC.107(49) certifications.
The IMO standard has failed to replicate shipboard conditions, which has led to an industry of basic and cheap separators that however require frequent filter maintenance and babysitting.

Magic Pipe

A magic pipe is a surreptitious modification to a ship’s oily water separator or other waste-handling equipment that allows waste liquids to be discharged in violation of maritime pollution regulations.
Such modifications to equipment may allow hundreds of thousands of liters of contaminated water to be discharged untreated, resulting in widespread pollution of marine waters.
To discharge untreated wastewater directly into the sea, a pipe can be improvised aboard a ship using available hoses and pumps.
Magic pipe cases frequently involve the falsification of records, as ships are required to keep documentation of waste and its treatment.
These cases usually result in hefty fines for shipping companies and even prison sentences for crew members. The pipe is dubbed magic” because it bypasses the ship’s bilge water separator directly overboard. As a result, the bilge water “magically disappears”.
The use of magic pipes continues to this day, as do efforts to improve bilge water treatment to eliminate the need for these shortcuts.

Whitebox

The Marinfloc Whitebox® is a failsafe overboard discharge monitoring and control unit. It is installed between the oily water separator and the overboard valve.
It prevents non-compliant discharge of bilge water and helps to protect the crew from accusations.
All vital discharge data is recorded and linked to the vessel’s GPS; the Whitebox® houses all necessary monitoring and control equipment for the overboard discharge.
A digital recorder stores all critical data such as oil content, valve settings, flow via the oil content monitor and overboard flow, door open/closed, vessel position, and time.

Ocean Guardian

Environmental operations planning

As the maritime industry continues toward the goal of sustainable operations, the need to develop an innovative solution to address the increasingly complex global environmental compliance requirements led to the creation of Ocean Guardian.
Launched in 2017, Ocean Guardian was developed by our US retailer, Total Marine Solutions, a worldwide leader in MARPOL-compliant environmental solutions.
Ocean Guardian matches a vessel’s GPS location to a proprietary global regulatory database. Ocean Guardian removes the guesswork from compliance by providing data on demand for baselines, applicable regulatory guidelines, and discharge notifications.
Verified and vetted by a third-party maritime law firm, we call this ‘assurance beyond compliance’ – knowing, not guessing.
Today’s complex regulatory environment makes it increasingly difficult for crew members to rely on often outdated hard-copy manuals.
Failure to have the latest regulations on hand can lead to accidental discharge, which in turn can lead to fines and reputational harm.
Ocean Guardian simplifies environmental operations, providing key decision-making data at your fingertips.

Key beneﬁts

- Client-accessible rules portal can be customized to include company or vessel-specific guidance.
Configurable and customizable
- The user interface is easily configurable to meet company and operator needs.

Marinﬂoc Advanced

Sewage Treatment System

Vessels differ in design, number of persons onboard, tank arrangement, trading area, age, etc. As the conditions differ from ship to ship, the ideal treatment system solution also differs from ship to ship.
Marinfloc has specialized in making the most out of what is at hand onboard to tailor a system that optimizes the use of tanks, space, and existing system components.
If something can be reused or converted, it is the most cost-effective, time-efficient, and environmentally friendly way to go.
Sometimes, tanks can be reused, repaired, or converted; sometimes, we need to construct new ones.
The crew are the vessel experts, and we are the experts in sewage treatment.
We love to come on board and work with the crew to find the ideal design together.
We provide tailor-made solutions to make the most out of your vessel.

Key beneﬁts

Baltic Sea approved as per MEPC.227(64) §4.2
Tailored solutions to get the most out of your vessel
Reduction of physical footprint using hull tanks to save space in the engine room
Reduction in environmental footprint by treating both black and grey water
Designed for retrofits

Sewage Treatment Systems for Special Areas

As of June 1, 2021, all passenger ships must comply with the latest MEPC addendum for sewage discharge in the Baltic Sea.
In addition to the present discharge parameters, the new set of standards requires additional treatment of phosphorus and nitrogen.
For the majority of new ships, this meant little or no modification because their equipment had already been prepared for this new set of rules.
However, for the older vessels, this meant either making a big investment or risking losing business by not sailing to the Baltics.
Due to the importance of this destination, not traveling the Baltic is not an option for most operators, resulting in a significant demand for sewage treatment conversions.
Like most other environmental retrofits, a sewage treatment upgrade is complicated since there are no quick fixes or shortcuts.
Sewage treatment, and particularly nitrogen removal, is accomplished in a multi-step process, therefore there is no simple upgrade so the vessel must typically construct a whole new system.
Recognizing the necessity for substantial rebuildings, the limitation of available space onboard, and the related costs for existing ships, the Marinfloc Neptumatic Sewage treatment system is designed for retrofits.
The ASTS unit can be easily dissembled and assembled again in place. The bioreactor can be a part of the vessel hull tanks to maximize the use of available space and bioreactor volume.
The entire treatment system is tailored to make the most of the conditions at hand.
The system flexibility even enables retrofitting of an almost 100-year-old tall ship that needs to prepare for worldwide operations including Baltic Sea Compliance.
The small footprint of the ASTS unit, utilization of existing tanks, and the possibility for on-site assembly are key features for vessels where hull penetrations are not possible.

Total organic load contribution

Blackwater (sewage) contributes only 25-30% of the total organic load. Grey water contributes by 70-75% but is not regulated by IMO.
We strongly encourage to also include grey water in the regulations.

Marinﬂoc Neptumatic Sewage Treatment System

Marinﬂoc ASTS unit

The Neptumatic Advanced Sewage Treatment System (ASTS) can be divided into Mechanical separation, Biological decomposition, Chemical flocculation, Forced flotation, Filtration, and Sterilization.
Black and grey water is mixed in a hull tank. The bioreactor can be hull-integrated or standalone depending on the individual conditions onboard. This is where BOD and nitrogen are reduced. The mechanical screen will separate coarse material and the ASTS treatment unit will remove suspended solids and phosphorus in the flocculation process. The forced flotation process will separate sludge from the water, and after the water has been filtered in the last stage, UV light neutralizes bacteria and viruses.

Marinfloc 25 years

25 years in the name of clean water

Bilge water: different points of view

On February 1st, 2021, we celebrated our 25th anniversary. During this period, we made a lot of good friends, but we also met other people who, strangely enough, didn’t like us that much.
One incident that comes to mind is when a gentleman claimed that we were the ones who invented the bilge water problem. He emphasized the point that, before Marinfloc, bilge water was hardly discussed.
Why waste effort when all separators functioned identically, and no one came close to cutting it? We later learned that he had discovered a new perspective.
The days of playing the “there is no solution on the market” card, in his opinion, were over.
The days of blissful ignorance where long gone.
We love to invent; it’s in our DNA and it shows in everything we do, but we can’t claim to have invented the bilge water problem; we did, however, come up with a solution.

All good stories start with a beginning

Marinfloc has been a catalyst for green technology and inspired innovation in the marine industry since the invention of the first oily water separator.

However, the story begins years before Peter

Lanzén and Benny Carlson put pen to paper and established the corporation. The year is 1988, Rick Astley wasn’t going to give you up and neither was the Swedish Green Party, which became the first new party to join parliament in 70 years. In 1988, Sweden also had one of the country’s worst marine animal extinction catastrophes in history where a significant portion of the seal population died and made headlines, sparking an already emerging green movement. Because seals are marine animals, the focus of attention was immediately turned to shipping as the source of the problem. It was eventually discovered that this tragic event was caused by a virus. However, there was a silver lining in that this occurrence raised new environmental awareness in the marine industry.

Wind of change

In the early 1990s, some shipowners began to implement new, ecologically friendly company policies, including the landing of all waste generated onboard their vessels. That might not seem like a big deal in 2022, but remember that 30 years ago, most waste was thrown or pumped overboard. Discharging untreated water overboard was never permitted, yet it was common practice due to a lack of technology and an outdated mindset. Bilge water is made up of 99 % water and 1 % oil, yet the amounts of bilge water can be substantial. Despite the low oil concentration in untreated water, there was no viable separation technique for the maritime market that could remedy the problem. Pumping all bilge water to shore, on the other hand, was – and still is – expensive, therefore, it became necessary to look into how this could be done more efficiently.

The Marinfloc story begins

While the shipping industry struggled to locate functional equipment from several suppliers, Stena Line, a Swedish shipowner, decided they needed to go elsewhere. Rather than scouring the globe for a solution, they assigned two of their engineers to the task. Peter and Benny had spent many years as expert mariners dealing with malfunctioning equipment on various ships. Knowing this, they were persuaded that the answer lay inland rather than at sea knowing that municipal water treatment facilities needed to take into consideration both efficiency and cost but also the quality of the effluent water. They soon discovered that most plants around the world used a technique known as flocculation, where a salt solution is used to collect and gather oil, chemicals, and other impurities so they can be easily separated and collected. Based on these findings, they began experimenting in a small test facility, where flocculation became a key component of the solution. The test equipment was expanded to the prototype and installed onboard the RoPax vessel Stena Danica. During the first year, the solution ended up saving USD 100,000.

Type approval and certification of the first Marinfloc unit

A second prototype was put on a sister ship shortly after, and the equipment was type-approved by the Swedish Maritime Administration and the classification society Det Norske Veritas in 1994 under the name MARINFLOC.
More units were installed as word got out that there was an Oily Water Separator that functioned. The demand for this functional technology grew in 1996, and Peter and Benny established their firm and began working full-time on developing and selling the equipment. This was the beginning of Marinfloc’s success story.
Marinfloc has been developing environmentally friendly water treatment systems for ships and offshore installations since that day.
The Marinfloc mission has always been clean water overboard, and our vision is a clean sea.
