Washing method for separation membrane module |
| abstract |
In a method for cleaning a separation membrane module in which filtration is performed through a separation membrane after mixing and stirring raw water containing particles having hardness higher than that of the separation membrane with an inorganic flocculant, (a) water on a membrane primary side in the separation membrane module is discharged outside the system after completion of the filtration; then (b) the membrane primary side in the separation membrane module is filled with water containing a chelating agent for a certain period of time; subsequently (c) the water containing the chelating agent on the membrane primary side in the separation membrane module is discharged outside the system; and then (d) backwashing discharge water in the separation membrane module is discharged while performing backwashing in which backwashing water is transferred from a membrane secondary side to the membrane primary side of the separation membrane module. |
