Reverse Osmosis Filtration
RO Plant is unit Operation used in treatment of water, waste water and sewage treatment plant. Reverse osmosis is a common process to purify or desalinate contaminated water by forcing water through a membrane. Water produced by reverse osmosis may be used for a variety of purposes including Portable Purpose, Drinking Water, Process Water, and Cooling Tower Make up Water etc.
Process Description :-
Reverse osmosis plants require a variety of pre-treatment techniques including softening, dechlorination, and anti-scalent treatment. Following pre-treatment, high levels of pressure send water through a semi-permeable membrane, which retains all contaminants but lets pure water pass through. Energy requirements depend on the concentration of salts and contaminants in the influent water; higher concentrations requires more energy to treat.
Target Impurities :-
- TSS
- Bacteria
- Virus
- Multivalent salts(TDS)
- Monovalent Salts (TDS)
Advantages :-
- For any dissolved salts RO is best.
- Compact in space.
- Low Opex cost
- Quality of treated water is very good.
