Ceramic microfiltration for treating secondary wastewater effluent: influence of pre-treatment on the operational performance

The use of ceramic MF was evaluated for a secondary wastewater effluent was done with no oxidant, chlorine and ozone as pretreatment and with in-line coagulation. Coagulation was required for effective control of organic fouling of the membrane. Ozone with coagulant was effective for operations but ozone cost could be prohibitive.
