Microfiltration
The GrahamTek Fine and Ultra Fine Filtration Products are available in both the Series 203 (8-inch) and Series 403 (16-inch) ranges. These ranges incorporate the MemspinPlus modular skid-mounted pressure vessel option. 
Application specific staged filtration options may be selected with membrane cut off ranging from 20 micron to 0.2 micron depending on the raw feed constituents and final product water quality requirements. In a cascade filtration configuration, the range provides particulate removal (MF+) molecular weight cut off (UF+) and color filtration options. MemspinPlus GrahamTek Memspin Range provides Fine & Ultra Fine Filtration for the removal of finely dispersed suspended and sub-micron particles without the use of any foreign chemicals. Memspin systems may be configured as pre-filtration or Fine Filtration processes for Reverse Osmosis Desalination for the treatment of high- and low- turbidity Sea, Brackish and Hard Waters including Industrial Waste, Commercially Recycled Waters and Municipal Waste Waters. The unique flow reversal feature together with a pneumatically enhanced hydraulic backwash (reverse fed) enables application specific alternating cross-flow and dead end operation.
