| titleOfInvention | MEMBRANE SEPARATION METHOD |
| abstract | membrane separation method membrane clogging by slime adherence is efficiently avoided and stable treatment can be carried out for a long period of time at low cost for a small amount of chemical substances without membrane deterioration and trihalomethane formation even if applied to water with counting of a large number of viable cells and extreme water quality conditions. the method comprises supplying water to be treated to a membrane separation apparatus 4, intermittent addition to the water to be treated of a combined chlorine-based agent comprising a sulfamic compound and repetition of a feeding period without addition in which water to be treated to be treated is supplied for 6-120 hours without the addition of the combined chlorine-based agent and an intermittent addition feeding period in which water to be treated is supplied for 0.5-40 hours under the addition of a combined chlorine-based agent in concentration of biofilm exfoliation at an early stage of biofilm formation during the feeding period without addition, where the viable cell count (log cfu / ml) of the water to be treated is 3 or more and the concentration of the agent based of combined chlorine in water in the intermittent feeding period is 0.5-20 mg / l as total chlorine and the amount of combined chlorine-based agent added in the intermittent feeding period ent is the quantity in which r represented by the formula [4] below is 3 or more. r = (feeding period with intermittent addition (h) x [1000 x concentration of intermittent addition (mg-cl / l)] ^ 2.5 / (feeding period without addition (h) ^ 3.0 x 10 ^ logcfu / ml [4 ] |
