METHOD FOR PRODUCING FABRIC REINFORCED CAPILLARY SHAPED MEMBRANES, ESPECIALLY FOR ULTRAFILTRATION

摘要

The invention relates to a membrane filter used in the treatment of water, comprising a head piece (1) consisting of a permeate collecting chamber (2) with a permeate outlet (3), and at least one bundle of fibres (4) made from capillary membranes (5) which are sealed on one end and are poured onto the head piece on the other side with an open end in relation to said permeate collecting chamber. The capillary membranes (5) are surrounded by untreated water for processing. Clarified liquid flows in the capillary membranes (5) to the permeate collecting chamber. The capillary membranes (5) in the bundle of fibres (4) are secured in a tightly packed manner to a connecting area of the head piece (1) whereby said area is not interspersed with flow channels for the untreated water. A fumigation device (8) through which air exits is arranged inside the bundle of fibres (4).
