Abstract
Filtration equipment within a press resistant housing with medium inlets and outlets, comprises a rotatable shaft with a device for rotating the medium to be treated, and >=filtration disc. The latter has a support permeable to the filtrate, connected to >=1 channel leading out of the housing, and is closed with a semi-permeable membrane through which the medium must pass to react the channel. Turbulent flow on the membrane producing better filtration characteristics. Method is applicable to solns, suspension, emulsions for ultrafiltration, reverse osmosis, sepn, conc.
