Reverse Osmosis Process

The Reverse Osmosis process, also known as hyper
filtration, is the finest filtration process known till date.
The process ensures reduction in particles as small as
ions from a solution. Reverse Osmosis uses a semi-
per meable 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, purer 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 does 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.

Auto Flushing System

The purpose of the Auto Flushing System is to help prevent scaling or fouling of the RO membrane
by providing a rapid rinse which washes away impurities from the membrane's surface and keeps
the membrane clean. It also offers the following benefits:-
Lowers reject water outflow
n
Improves "TDS" rejection rate i.e increases RO membrane efficiency
