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.
The Reverse Osmosis process uses a semi-permeable membrane to reduce salts from
potable/brackish water. In Reverse Osmosis, water pressure is applied to the impure water inlet
resulting in the squeezing of purer water from concentrated end of the membrane towards the
diluted end. Dissolved salts present in the water in the form of 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 the RO membrane. These rejected impurities, suspended on the
concentrated end of the membrane, are then washed away as a stream of waste water, thus
preventing the membrane from clogging.
Ultra Filtration is a separation process that uses membranes with pore size in the range of 0.1 to
0.01 micron. UF membrane removes high molecular-weight substances, colloidal materials and
organic/inorganic polymeric molecules including bacteria and viruses. Low applied pressure is
therefore sufficient to achieve high flux rates from an Ultra Filtration membrane.
