Reverse Osmosis is a very fine filtration process, which occurs at a molecular level. This process involves forcing water through a semipermeable membrane, which allows only a given size of the molecule to pass and rejects the rest. In effect, the pores or holes in the membrane are so small that most of the harmful minerals and chemicals cannot pass, while water molecules pass through.
Ultra Filtration System
Ultrafiltration and Reverse Os (NF) are all pressure-driven membrane separation process. UF filter media is UF membrane, configured as flat type, tubular type and hollow fiber type. UF process is the separation process in relation with pore size, and the pore size is between RO (NF) and MF (0.001-0.1μm),that is to say UF process the separation from big molecules to small molecules. In short, ions and small molecules, dissolved in the raw water, permeate to be the UF permeate, while particles larger than the membrane pore size are concentrated as concentrate, such as big protein molecules, microorganism, colloid, suspending substance etc.
