This paper describes a process comprised of ion exchange, in-line coagulation and ceramic microfiltration (MF) tested for treating surface waters in southwest England. The membrane could operate at the nominal flux of 109 lmh. The process handled abrupt water quality changes by adjusting the coagulant dosage and with the normal course of backwashes (BW) and chemical enhanced backwashes (EBW). The process produced excellent water quality, with, on average 83% removal of dissolved organic carbon (DOC) and nearly complete removal of suspended solids.
