Reverse osmosis is used to reduce dissolved solids from feed waters with salinities. Osmosis is a special case of diffusion in which the molecules are water and the concentration gradient occurs across a semi permeable membrane.

Osmosis can be slowed, stopped, or even reversed if sufficient pressure is applied to the membrane from the “concentrated” side of the membrane. Reverse osmosis separation technology is used to remove dissolved impurities from water through the use of a semi-permeable membrane. Pressure is used as the driving force for the separation. The technology is also very effective at removing bacteria, pyroxenes, and organic contaminants.
Filtering osmosis reverse system
Water purification means removing of contaminants from water to produce drinking water. Boiling of water destroys
reverse osmosis filter
most of the microorganisms but does not remove technological wastes or heavy metals. Reverse osmosis water filtration is considered by many to be the most effective way of purifying drinking water. It is also one of the methods used to desalinate seawater. Sometimes reverse osmosis is used to purify liquids in which water is an undesirable impurity like ethanol. The reputed Italian company, Velo Group utilizes reverse osmosis plant based on ultra and nano filtration under pressure or under vacuum which is often used in commercial and residential water filtration.
