Reverse Osmosis Process

The Reverse Osmosis process, also known as hyper filtration, is the finest filtration process known till date. The process ensures 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 is “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 it is just beyond 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 itself. Thus, it is essentially killed and cannot cause infection. This process of DNA modification is called inactivation.

Computer Controlled Operation*

To ensure delivery of purer and healthier water, a micro-processor is installed in the purifier that periorms the following functions: –

UV Stabilisation 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 seconds delay to UV lamp when the purifier is switched on, During this period, only the UV lamp is switched on and other electrical devices of tha purifier are switched off.

Purification Delay: To ensure that the idle water lying in the internal pipes and in the UV chamber is disinfected before being passed into the storage tank, the system provides 5 second delay when the purifier is 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 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.

Automatic Operation

• The purifier automatically shuts off when the storage tank is full
• The purifier does not start when inlet water supply pressure falls below 0.3 kg/em?
• 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

‘This system has been tested for the teatment of water containing pentavalent arsenic (also known as As (V), As (+5), or arsenate) at concentrations of 0.30 mg/L or less. This system reduces pentavalent arsenic but may not remove other forms of arsenic. This system is to be used on water supplies containing detectable free chlorine residual or on water supplies that have been demonstrated to contain only pentavalent arsenic. Treatment with chloramines (combined chlorine) is not sufficient to ensure complete conversion of trivalent arsenic to pentavalent arsenic, Please see the Arsenic Facts section of the performance data sheet for further information’.

Arsenic Facts

Arsenic (As) is a naturally oocurring contaminant found in many ground waters. It generally occurs in two forms (valences or oxidation states): pentavalent arsenic {also known as As(V), As(+5), or arsenate) and trivalent arsenic (also known as As(iill, As(+3), or arsenite). in natural ground water, arsenic may exist as trivalent arsenic, pentavalent arsenic, or a combination of both, Although both forms of arsenic are potentially harmful to human health, trivalent arsenic is considered more harmful than pentavalent arsenic, More information about arsenic and its toxicity can be found on the U.S. Environmental Protection Agency website at http://wwwv.epa.gov/safewater/arsenic.html
This system is designed to remove only pentavalent arsenic. This teatment system does not provide a feature for conversion of trivalent arsenic to pentavalent arsenic, The system may remove some trivalent arsenic, however, it has not been evaluated for its ability to remove trivalent arsenic, Trivalent arsenic is generally more difficult to remove from drinking water than pentavalent arsenic. Trivalent arsenic can be converted to pentavalent arsanic in the presence of an effective oxidant such as free chlorine.
The arsenic in water containing detectable free chlorine or that has been treated with another effective oxidant will be in the pentavalent arsenic form.4 Treatment with chloramine (combined chlorine) is not sufficient to ensure complete conversion of trivalent arsenic to pentavalent arsenic,
