초록 ▼

A multilayer membrane separator which permits serial and tangential contact of a retentate with a plurality of membranes within the separator. The separator is formed from a plurality of contiguous separator units each consisting of two membrane layers, two retentate layers, a filtrate spacer layer and two adhesive layers. The adhesive layers, in cooperation with a liquid inlet to the separator and a liquid outlet from the separator effect the desired retentate flow and prevent mixing of retentate and filtrate.

대표청구항 ▼

Apparatus suitable for filtering a liquid composition said apparatus having a primary inlet for said liquid composition, a primary outlet to remove filtrate from said liquid composition and a secondary outlet to recover retentate from said liquid composition which comprises: at least two membrane units, each of said membrane units consisting of a first membrane layer, a second membrane layer, a filtrate spacer layer interposed between said first and second membrane layers, a first adhesive layer interposed between and contiguous to said first membrane layer and said spacer layer, and a second adhesive layer interposed between and contiguous to said second membrane layer and said spacer layer, a first retentate spacer in direct contact with said first membrane on a membrane surface opposite a membrane surface in contact with said spacer layer and a second retentate spacer in direct contact with said second membrane on a membrane surface opposite a membrane surface in contact with said spacer layer, each of said retentate spacers having a plurality of channels each having an inlet end and an outlet end and adapted to provide flow of said liquid composition in said channels tangentially across said membrane layers contacting said retentate spacers, inlet means for introducing said liquid composition into the inlet ends of channels of said first retentate spacer to effect liquid flow in a first direction across said first membrane layer, a row of membrane channels in said first membrane layer in liquid communication with the outlet ends of the channels of said first retentate spacer, the row of membrane channels being in liquid communication with the inlet ends of the row of channels in said second retentate spacer through channels in said adhesive layer and channels in said second membrane layer thereby to effect liquid flow across said second membrane layer in a direction opposite said first direction of liquid flow across said first membrane layer, an outlet means for removing filtrate passed through said first membrane and said second membrane and through said filtrate spacer layer separately from retentate, and outlet means for removing said liquid composition from the outlet ends of said second retentate spacer, said adhesive layers providing seals to prevent admixture of filtrate with retentate.
