Reverse Osmosis Process

The Reverse Osmosis process, also known as hyper filtration, is the finest filtration process known till date. The process ensures the reduction of particles as small as ions from a solution. Reverse Osmosis uses a semi permeable membrane to reduce salts from potable / brackish water. In Reverse Osmosis, water pressure applied to the concentrated side forces the process of osmosis into reverse. Under enough pressure, treated water “squeezed” through the membrane from the concentrated side to the diluted side. Salts dissolved in water as charged ions are repelled by the RO membrane. The rejected impurities on the concentrated side of the membrane are washed away in a stream of waste water, and thus do not get accumulated as in a traditional filter.

UV Process

The UV light has shorter wavelength (higher energy) than the visible light. It is called ultra-violet because itis just beyond the violet light in the light spectrum. Technically, the ultra-violet light is defined to be any wavelength of light, which is shorter than 400 nanometer.

UV rays, which penetrate into the micro-organisms, are absorbed by the DNA of the pathogen in the water. The DNA is altered in such a way that the pathogen cannot reproduce itseff. Thus, itis essentially kiled and cannot cause infection. This process of DNA modification is called inactivation.

Note: The purified water stored in the tank is disinfected using UV LED, which automatically switches on for 30 minutes in a two hour cycle.

Auto-flushing System

The purpose of the Auto-fiushing system is to help prevent scaling or fouling of the RO membrane by providing a rapid finse which washes away impuriies from the membrane’s surface and keeps the membrane clean. It offers following benefits.

• Lowers rejected water outfiow
• Improves “TDS” rejection rate e increases RO membrane’s efficiency
• Extends the life of the RO membrane

UV Fail Alarm*

KENT Crown Plus-B Mineral RO™ Water Purifier has an in-built feature that sounds an audible alarm if the UV lamp malfunctions. This feature is provided to ensure purity. This UV Fail Alam will sound as follows:
Single short beeps after every two seconds. The purfier wil stop its purfication process in such a circumstance.

In case of UV LED failure it sounds an alarm with two beeps.

In case such an alarm is audible, call the service technician for help.

Filter Change Alarm*

KENT Crown Plus-B Mineral RO™ Water Purifier has an in-built feature that sounds an audible alarm to indicate replacement time for fiiters. This alarm will be audible after 700 hrs of use since the last filter change (or since the time of installation). The Filter Change Alarm will sound as follows: 4 short beeps after every two seconds; for 30 seconds. The alarm will repeat after every 2 hours of use.

In case such an alam is audible, please cal the service technician and request him to change the fiters of the purifier. However, if the fiters are not changed within the next 60 hours of operation, the purifier will stop functioning to enstre purity and hygiene. The following alarm will be audible after 60 Hrs. A continuous beep for an infinite time.

In case, such an alarm is audible, kindly switch off the purifier and call the service technician to replace the fiters. In such a circumstance, the purifier will not function unless the fiiters are changed.

Computer Controlled Operation

To ensure delivery of purer and healthier water, a micro-processor is installed in the purifier that performs the following functions:
UV Stabilization Delay: To ensure that the UV lamp is pre-heated and is working at its optimum level before it starts disinfecting water, the controller provides a two second delay to the UV lamp when the purifier is switched on. During this period, only the UV lamp is switched on and other electrical devices of the purifier are switched off.
Purification Delay: To enstre that the idle water lying in the intermal pipes and in the UV chamber is disinfected before being passed into the storage tank, the system provides 5 second delay when the purifier s switched on. During this time, the UV lamp Kills all micro-organisms that may be in the water inside UV chamber. After this delay, all other electrical devices such as the booster pump and solenoid valve are switched on to start normal purification process.
Audible Alarm: The controller also controls the timing of UV Fail Alarm and the Filter Change Alarm.

• Tested & certified by TUV-SUD South Asia (P) Ltd.

Automatic Operation

• The purifier automatically shuts off when the storage tanks are full
• The purifier automatically flushes & cleans the RO membrane on periodic intervals
• The purifier does not start if the inlet water supply pressure is below 0.3 kg/cm?
• The purifier automatically restarts when water level drops below the maximum
• The purifier does not allow any water rejection in absence of electricity/when tank is full

TDS Adjustment

A unique feature in KENT Crown Plus-B Mineral RO TM Water Purifier is the TDS control valve, which is not available in any other domestic water purifier till date. This feature allows the user to control the content of natural minerals (TDS) in purified water. To increase the TDS level, the user can turn the screw of the valve anti clockwise; it will result in more mineral content in treated water. To reduce the TDS level, user can turn the screw valve clockwise, it will result in less mineral content in treated water. We recommend the TDS of the purifier to be kept at lowest but not below 50 mg/l.

Technical Specifications

• Purification capacity tested for raw water having TDS level of 750 ppm at room temperature.

Testing Information

The System has been tested according to IS 10500:2012 (Standards for drinking water as per Bureau of Indian Standerds) for reduction of the hazardous substances.
