HOLLOW FIBER MEMBRANE OR CAPILLARY MEMBRANE FILTER AND WATER FILTRATION METHOD USING SUCH A FILTER

摘要

A method of filtering water and a membrane filter (100). The filter (100) includes a collecting chamber (120) and a plurality of membranes (110). Each membrane (110) includes a sealed free end (111), a tube cavity, and an open potted end (112). The open potted end (112) is in fluid communication with the collecting chamber (120). The sealed free end (111) can move laterally substantially freely, causing solids on external walls of the plurality of membranes (110) to fall by gravitational force to a bottom portion of a reservoir, and to be drained out of the system. Unfiltered water can be directed toward the open potted ends (112) to scrub the membranes (110) with unfiltered water without entangling the membranes (110).
