Reverse Osmosis Membrane Technology Services

Reverse osmosis membrane is an artificial semi-permeable membrane with certain characteristics made to simulate a biological semi-permeable membrane. Reverse osmosis technology: Under the effect of osmotic pressure higher than that of the solution, other substances are separated from the solvent on the basis that they cannot pass through the semi-permeable membrane. The membrane pore size of reverse osmosis membranes is very small, so they can remove soluble metal salts, organic matter, bacteria, colloidal particles, and heat-generating substances, i.e., they can trap all ions, and can be used for the concentration of active ingredients in natural products.

Process Parameters Affecting Reverse Osmosis

Recovery rate

A high recovery rate will produce a high brine concentration, which can cause a decrease in permeate flow and an increase in salt passage, leading to membrane contamination or excessive dissolved salt precipitation in concentrated brine, resulting in membrane fouling.


Temperature has an effect on both osmotic pressure and water flux. Water flux is also proportional to temperature and is usually proportional to the temperature-dependent viscosity.


For a given set of feed water conditions, increasing the pressure will result in a higher water flux per unit membrane area.

Pressure Density

Pressure density is caused by the spiral deformation of the polymer membrane throughout the operating time. The pressure density is related to the membrane material, the pressure applied and the temperature.

Concentration Polarization

Concentration polarization increases the osmotic pressure of the solution on the membrane surface, which causes a decrease in water flux and an increase in salt migration through the membrane.
