Patent ID: 8444863

Claim:
A method of treating a microfiltration filter having an influent side and an effluent side to improve performance of the microfiltration filter comprising, sealing imperfections in surfaces of the microfiltration filter by flushing the filter with an aqueous suspension of particulates to achieve a coating of particulates of an areal density of about 0.01 mg/cm 2 to about 20 mg/cm 2 on surfaces of the filter, the suspension having particulates in an amount of about 0.01 gm/l to about 20 gm/l, the particulates having median particle diameter of about 5 μm to about 50 μm and a particle diameter size range of about 0.1 μm to about 200 μm, where flushing of the filter is performed at a flow rate of about 0.02 ml/min/cm 2 to about 2 ml/min/cm 2 .
