Nanofiltration is a process of filtration in the range between  reverse osmosis and ultrafiltration that uses semi-permeable membranes with a pore size of about 0.001micras, rejecting organic molecules with molecular weight greater than 200 Daltons. Differentiating characteristic of the reverse osmosis process, the monovalent ions are rejected by 30% and 60%, and divalent between 90% and 98%. This difference in rejection can operate at very low ...


Tangential Microfiltration is a process of physical-mechanical separation.As the medium flows tangentially through the membranes, the filtrate or permeate moves at right angles. This filtration method is called “dynamic filtering”. To separate the compounds do not undergo any chemical modification, which means they can be recovered. Choosing the appropriate pore size, the low molecular weight substances can cross the membrane while the ...
