CPA2-4040 food beverage pure water membrane
Introduction:Reverse osmosis membranes are artificial semi-permeable membranes with certain characteristics that mimic biological semi-permeable membranes and are the core building blocks of reverse osmosis technology. The principle of reverse osmosis technology is that other substances cannot pass through a semi-permeable membrane under the effect of an osmotic pressure higher than that of the solution, and these substances and water are left behind.

Product parameter:
Reverse osmosis is the process of applying a pressure greater than the osmotic pressure of the solution on the concentrated solution side, forcing the water molecules to pass through the semi-permeable membrane into the dilute solution in the reverse direction (opposite to the natural direction of osmosis), as in the reverse osmosis process, the water molecules on the concentrated solution side flow through the semi-permeable membrane into the dilute solution, while the vast majority of the solutes (dissolved solids) cannot pass through the membrane and are retained. Therefore, the concentrated solution is further concentrated, or dehydrated, and the dilute solution is diluted and purified, or desalinated.
