The FlatQ® is an microfiltration membrane with an assymetrical pore structure of 0,1 micron, manufactured from PVDF, with a high chemical resistance. The membrane has a pore structure that guarantees good permeate quality and high productivity. Its smooth surface ensures low filtration reluctance and an excellent anti-pollution ability. The membranes are easy to clean and backwash is therefore not necessary. The FlatQ® is easy to replace, which makes it ideal for retrofit of FlatQ as well as other flat sheet systems.
