Abstract

According to one mode in the present embodiment, provided is a membrane filtration method which comprises adding a coagulant to treated water, said treated water having been prepared by subjecting water to be treated to a flocculation and settling 5 treatment by adding a flocculant thereto or a flocculation and dissolved-air floatation treatment, and then performing membrane filtration treatment(s) such as an ultrafiltration membrane treatment and/or a precision filtration membrane treatment.
