Advanced Treatment of the Municipal Wastewater by Lab-Scale Hybrid Ultrafiltration

In this study, hybrid ultrafiltration which involves adsorption onto activated carbon and/or coagulation was tested for the removal of ibuprofen, caffeine and diclofenac from municipal wastewater treatment plant effluent (c0 = 2–3 µg/L). Ultrafiltration in combination with powdered dose 5 mg/L separately or coagulants (FeCl3, 4 mg Fe (III)/L and, natural coagulant isolated bean seeds, 33 µL/L). addition to organic micropollutants, As, Cr, Cu Zn also (c0~100 The research conducted on a laboratory pilot (capacity 30 L/h, in-out dead-end filtration, flux 80 L/m2h). best results were obtained when PAC is combined FeCl3 (removal efficiency 42–87%). did not show benefits micropollutants compared other processes, but both had similar effects content metals As Hybrid membrane processes proved be most efficient (44–87%) Cr (33–87%) removal. lowest determined (˂19%). removed 5–33% matter, depending type coagulant; 57–87% total nitrogen PAC/FeCl3/UF partially effective removing phosphorus (11–39%).
