<p>A water filtering hollow yarn membrane module, which consists of hollow yarn membranes, a fixing member to which the end portions of the hollow yarn membranes are fixed as the end portions thereof are kept open, and a structure for supporting and housing the fixing member, and which is adapted to suck water from the outer surfaces of the hollow yarn membranes into the interior thereof to filter the same with the surfaces of the hollow yarn membranes washed intermittently or continuously, each hollow yarn membrane consisting of a braided material using the hollow yarn membrane itself as weft yarn, a cross section, which extends perpendicularly to the hollow yarn membranes, of the fixing member being elongated and substantially rectangular. In this module, the hollow yarn membranes rarely stick to one another to form a unitary body, and the washing of the surfaces of the hollow yarn membranes can be done efficiently in parallel with the filtration of water, so that the deterioration of the filtering function of the module rarely occurs.</p> |
