Recently, wastewater reuse technology has gained attention as a potential solution to water scarcity problems. Membrane-based techniques for foulants separation are widely used in wastewater treatment and reuse (Petrinic et al., 2015; Sadr Ghateni et al., 1998). However, one of main challenges faced during filtration is membrane fouling caused by the deposition of foulants, such as effluent organic matter (EfOM), colloids, and particles, on the membrane surface. Several methods are used to reduce this membrane fouling for wastewater reuse such as ozonation, coagulation, UV oxidation, and activated carbon use (Jin et al., 2016; Acero et al., 2016). The objective of this study was to test the efficiency of pre-ozonation and coagulation method in removing pollutants, such as colloids and EfOM, from wastewater, and in reducing the irreversible resistance of ultrafiltration (UF) membrane...
