The acronym for Stainless Steel Institutional Reverse Osmosis Plant is SS RO PLANT. The SS RO System is based on reverse osmosis, often known as hyper-filtration. Water produced by reverse osmosis purifiers are the most reliable sources of water purification. To accommodate your unique demands at home or at work, these water purifiers are available in a range of tank capacities. Reverse osmosis, filtration, ion exchange, carbon adsorption, and adding a chemical to equilibrium the optimal water conditions are some of the methods used to purify water in this type of RO system.
