Reverse Osmosis also known as Hyper Filtration,
is the finest filtration process known till date. The
process ensures removal of particles as small as
ions from a solution. Reverse Osmosis process
uses a semi-permeable membrane to reduce the
dissolved salts from potable / brackish water. In
Reverse Osmosis, water pressure is applied on the
inlet impure water resulting into the squeezing of
purer wa ter from the concentra ted end of
membrane towards the diluted end. Dissolved
salts present in water as charged ions get repelled
by the RO membrane and are not allowed to pass
through. Similarly, bacteria and germs are also
blocked by the ultra-fine pores of RO membrane. These rejected impurities suspended on the
concentrated end of the membrane are washed away in a stream of waste water preventing the
membrane from clogging.

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 offers following benefits:
n
Lowers outflow of rejected water.
n
Improves TDS rejection rate i.e increases RO membranes efficiency.
n
Extends life of RO membrane.
UV Process
The ultra-violet (UV) light has shorter wavelength (higher energy) than visible light. It is called ultra-
violet because it is just beyond violet light in the light spectrum. Technically, ultra-violet light is
defined to be any wavelength of light, which is shorter than 400 nanometer.
UV rays, which penetrate into micro-organisms, are absorbed by the DNA of 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.
