ROreverse osmosis equipment working principle:
Reverse osmosis device:

Reverse osmosis is a process that is opposite to natural osmosis flow. By applying far enough pressure to the solution end, the natural osmosis pressure of the solution(pure water) can be reviewed to make it flow in the opposite direction.

The two most commonly used terms for reverse osmosis are "salt removal rate" and "recovery rate." The TDS quantity removed by the membrane is called the rate of removal of salt, expressed as a percentage, and 99 % of the rate of removal means that 99 % of the soluble solid in the water is removed by the membrane. Calculate the salt removal rate using the following formula:
Salt removal rate(%) =(original water TDS-product water TDS) / original water TDS × 100

The amount of water that can be recovered for use accounts for a comparative recovery rate of the amount of water that is processed into the reverse osmosis device. Calculate the recovery rate using the following formula: Recovery rate(%) = product water/primary water flow x 100

The amount of salt removal of the semi-permeable membrane is proportional to the TDS concentration of the original water and has nothing to do with the pressure of use. However, the yield of pure water is proportional to the pressure of use of the membrane. Increasing the operating pressure will increase the water production without affecting the amount of salt removal. Therefore, the higher the pressure of use, the better the water quality and the more water production(of course, within the allowable pressure range). A high recovery rate can be considered to reduce the operating cost of the system.

Soluble solids, organic matter, colloidal substances and bacteria in water were removed by semi-permeable spiral film. The raw water is sent to and through the reverse osmosis membrane at a certain pressure. The water passes through the tiny aperture on the membrane and is collected to obtain pure water. The impurities in the water are concentrated in the cut-off fluid and discharged. RO can remove more than 96 % of soluble solids in raw water, more than 99 % of organic matter and colloids, and almost 100 % of bacteria.

RO equipment is currently one of the most advanced equipment for the production of pure water in water treatment equipment in the world. Its operation cost is low, economical, convenient, and reliable. It is the preferred pure water preparation equipment for businesses.
