Title: Method for washing separation membrane of waste water treatment apparatus
Inventor: MATSUBARA MASAAKI
IPC: C02F1/44
Filed: 2003-01-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for washing a separation membrane of a waste water treatment apparatus, by which the separation membrane used in a membrane separation activated sludge process is efficiently washed effectively by predicting the timing to use an acid together with an oxidizer while saving labor, time and cost.  <P>SOLUTION: The operation time T<SB>B</SB>when the methods for washing the separation membrane are changed is predetermined on the basis of an average operation time T<SB>A</SB>when the inter-membrane differential pressure reaches a prescribed pressure P<SB>D</SB>in the normal operation of the waste water treatment apparatus. The separation membrane is washed by using sodium hypochlorite as the oxidizer or by using sodium hypochlorite and then oxalic acid, or the like, according to the prediction whether an operation time T<SB>E</SB>when the inter-membrane differential pressure reaches the prescribed pressure P<SB>D</SB>at this time is longer or shorter than the predetermined operation time T<SB>B</SB>. In other words, the time to change the washing methods can easily be controlled suitably. As a result, the separation membrane can be efficiently washed effectively since only the oxalic acid-used pickling is added when the filtration resistance of the separation membrane ascends rapidly.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
