Abstract: ABSTRACT A MULTIPLE CHANNEL CAPILLARY FILTRATION MEMBRANE AND PROCESS THEREOF The present invention relates to a multiple channel (1) capillary filtration membrane and process thereof. The multiple channel (1) capillary filtration membrane featuring a hexagonal close-packed arrangement of cylindrical channels (1) and a multi-layer structure. The membrane consists of an internal core polymeric layer encompassing all channels formed with one polymer concentration and an outer coating polymeric layer formed with a different concentration, optimizing flow resistance and filtration efficiency. The manufacturing process involves extruding polymer solutions and coagulant (10) through a nozzle (25), which ensures the precise formation and alignment of the channels (1) within the membrane.
