Filtration Apparatus And Operation Method Therefor
Abstract: Provided is a filtration apparatus comprising a flow control means and a separation membrane module, wherein the filtration apparatus has a liquid flow detection means for detecting liquid flow at a chosen site and an external control means for controlling the state of the flow control means. The external control means has: a target range-setting step for setting a target flow range A that includes a target liquid flow at the chosen site; a control state-recording step for recording the state S of the flow control means when, after starting supply of a liquid being filtered or a back-wash solution to the separation membrane module, the liquid flow at the chosen site first enters the target flow range A; a state-setting step for putting the flow control means in the state S recorded by the control state-recording means; and a flow control step for keeping the liquid flow in the target flow range A.
