Two-Stage RO Water Treatment Reverse Osmosis Equipment – 3D Model SolidWorks

Reverse osmosis, also known as reverse osmosis, is a membrane separation operation that uses pressure difference as a driving force to separate solvents from solutions. When pressure is applied to the liquid on one side of the membrane, when the pressure exceeds its osmotic pressure, the solvent will reversely permeate in the opposite direction of natural osmosis. As a result, the permeated solvent, i.e., the permeate, is obtained on the low-pressure side of the membrane; and the concentrated solution, i.e., the concentrate, is obtained on the high-pressure side. If reverse osmosis is used to treat seawater, fresh water is obtained on the low-pressure side of the membrane, and brine is obtained on the high-pressure side.
Because it is in the opposite direction of natural osmosis, it is called reverse osmosis. According to the different osmotic pressures of various materials, a reverse osmosis pressure greater than the osmotic pressure can be used, i.e., reverse osmosis, to achieve the purpose of separation, extraction, purification and concentration.
