| titleOfInvention | Membrane separation method |
| abstract | PROBLEM TO BE SOLVED: To efficiently prevent clogging of a membrane with a small amount of medicine and low cost, and to stably treat for a long period of time even in a water quality with a large number of viable bacteria and slime severe conditions, without deterioration of a permeable membrane and generation of trihalomethane. . When a membrane separation treatment is performed by intermittently adding a bound chlorinating agent containing a sulfamic acid compound to water to be treated having a viable cell count (log CFU / mL) of 3 or more, the bound chlorinating agent is not added. An intermittent addition water supply period in which an additive-free water supply period in which water is supplied for 120 hours and an intermittent addition water supply period in which a combined chlorinating agent having a concentration for peeling the biofilm is added at the initial stage of biofilm formation and water is supplied for 0.5 to 40 hours is repeated. The combined chlorine agent concentration is set to a concentration at which the total chlorine concentration is 0.5 to 20 mg / L. [Selection] Figure 1 |
