BW 4040 ULP Reverse Osmosis RO Membrane for Industrial RO Water Purifier
The osmotic pressure of reverse osmosis equipment is a function of the concentration of salt or organic matter in the water. The higher the salt content, the higher the osmotic pressure. When the influent pressure remains unchanged, the net pressure will decrease and the water production will decrease. The salt permeability is proportional to the salt concentration difference between the front and back sides of the reverse osmosis membrane. For the same system, the operating pressure and the conductivity of the product water are also different depending on the salt content of the feed water. For every l00ppm increase in the salt content of the feed water, the feed water pressure needs to increase by about 0.007MPa. rate also increased accordingly. Suspended solids in water refer to the substances that remain on the surface of the filter material while the water is being filtered, and are mainly composed of particles. The high content of suspended solids will lead to serious blockage of reverse osmosis and nanofiltration systems quickly, affecting the water production and water quality of the system.
