Reverse Osmosis Plants
RO unit uses the reverse osmosis process to remove dissolved solids from brackish or saline water. Exploding population, industrial effluents, and reckless deforestation have depleted natural sources of pure water. Dependence on erratic monsoons to replenish these sources has proved extremely inadequate & expensive. Good management of existing water resources and untapped sources, along with recovery and recycling of Industrial effluents & municipal waste water, seem absolutely essential for the future of mankind.
Principle of Reverse Osmosis
Reverse Osmosis system works on the principle of Osmosis, reverse osmosis is the process of forcing a solvent from a region of high solute concentration through a semipermeable membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure. When two solutions with different concentrations of a solute are mixed, the total amount of solutes in the two solutions will be equally distributed in the total amount of solvent from the two solutions. Instead of mixing the two solutions together, they can be put in two compartments where they are separated from each other by a semipermeable membrane. The semi permeable membrane does not allow the solutes to move from one compartment to the other, but allows the solvent to move.
