A method for membrane filtration of effluent water containing suspended matter reduces membrane clogging and improves filtration capacity of the membrane. The method includes adding a dose of a preselected coagulation reactant to the effluent before the effluent passes over the membrane. The added dose is a fraction of the coagulating reactant dose (X) that would render the zeta potential of the effluent equal to zero. The range of the added dose is X/30-X/80. The suspended matter in the effluent is subjected to the added dose of coagulation reactant for destabilizing the suspended matter. |
