Hollow yarn membrane module, hollow yarn membrane module unit and the membrane filtration equipment for clarifying and the operational method of using this

摘要

It offers the membrane filtration equipment for clarifying and the operational method of using hollow yarn membrane module unit and the said unit which use hollow yarn membrane module and the said module where pressure tightness of the hollow yarn membrane fixed part does not decrease even with when it increased the membrane area in the module which uses the seat condition hollow yarn membrane being superior in washing characteristic. Hollow yarn membrane membrane module, the plural seat condition hollow yarn membranes (1) and while at least one side of that end is kept in opening state, the fixed component which outline parallel is locked (2) has the said plural seat condition hollow yarn membranes (1), end face form the side which the said fixed component (2) the hollow yarn membrane exposes is outline rectangular, at the same time, end face form the side where the said fixed component (2) the hollow yarn membrane opens has become outline circle.
