Product Details

Desalination 4-inch Low Pressure Reverse Osmosis RO Membrane for RO Water Purifier

 

RO membranes are generally made of polymer materials. Such as cellulose acetate film, aromatic polyhydrazide film, aromatic polyamide film. The diameter of the micropores on the surface of the RO membrane is generally between 0.5 and 10 nm, and the permeability is related to the chemical structure of the membrane itself. Some polymer materials have good salt repellency, but the water penetration rate is not good. Some polymer materials have more hydrophilic groups in their chemical structure, so the water penetration rate is relatively fast. Therefore, a satisfactory reverse osmosis membrane should have an appropriate penetration or desalination rate.

RO membranes, in general, remove 90% or more of the contaminants present in the water, including TDS. When the TDS levels of your water source changes, it will affect the quality of the purified water output from your reverse osmosis system.
