Document Type and Number:
Japanese Patent JP2015077530
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a cleaning method of a membrane module and a water production method where equipment cost, the installation space of equipment and electricity charge can be reduced and contaminants adhered to the whole surface of a separation membrane can be significantly peeled and removed.SOLUTION: In a water production method where raw water is supplied to the lower side of the separation membrane primary side of a membrane module 4 which is disposed so that the direction of a separation membrane is vertical and membrane-filtered water is obtained from a separation membrane secondary side by filtering the raw water with the separation membrane, a cleaning step where aspirator supply water is supplied to an aspirator 12 and a gas-liquid mixed fluid discharged from the aspirator 12 is supplied to the lower side of the separation membrane primary side of the membrane module 4 is temporarily performed.
