6000 TDS Low Pressure RO Membrane for Industrial Brackish Water RO System
As the most important component of water treatment, the reverse osmosis membrane has very strict requirements on the quality of the influent water during use. Because the pore size of the reverse osmosis membrane is very small, it is necessary to remove suspended solids, microorganisms, colloidal substances and organic matter as much as possible, otherwise the quality of the influent water does not meet the requirements. It is easy to cause blockage and pollution of reverse osmosis membrane.
Factors affecting reverse osmosis membrane:
Inlet water pressure, inlet water temperature, inlet water PH value, inlet water salt concentration.
Increasing the water inlet pressure can increase the water production and the desalination rate, but the salt permeation is basically unchanged, and the water production can be increased. When the inlet water pressure exceeds a certain value, the water production and desalination rate will not increase, because each membrane has an upper limit. As the inlet water temperature increases, the water production will also increase, and the pH The value has little effect on the water yield, but has a relatively large impact on the desalination rate.
