This study presents the results of filtration tests with inside-to-out polyethersulfone ultrafiltration membranes combined with coagulant and powdered activated carbon addition to polish wastewater before discharge. Long-term follow-up of the operation demonstrates that such membranes can be used as a polishing step and that the membranes do not suffer from any performance or integrity loss. Results show that organic content is reduced by approximately 33 % for DOC, 54 % for COD and that an overall reduction of 80% of the micropollutants can be reached with such hybrid process. The study finally presents reductions of the operational expenditures which can be achieved by discontinuous coagulant dosing.
