Patent number: 4235722Abstract: A liquid treating unit includes a module comprising a channel member for collecting a product liquid for recovery; a semipermeable membrane member liquid-tightly joined to the channel member and made from a semipermeable membrane strip by alternately folding the strip longitudinally thereof to provide feed liquid passages and product liquid passages on the front and rear sides of the membrane respectively, each pair of product liquid passages defining leaf portions of the membrane being adhered at each end of the passage to liquid-tightly close the product liquid passage only; spacers inserted into the feed liquid passages; and a covering member surrounding the outer periphery of the membrane member. The feed liquid passages therefore have a regulated cross sectional area to permit the feed liquid to flow through the passages in parallel and straight direction at an increased speed relative to the membrane surface, ensuring a reduction in dead space and efficient use of the membrane.Type: GrantFiled: May 15, 1978Date of Patent: November 25, 1980Assignee: Daicel Ltd.Inventor: Yasuhiro Sakaguchi
