Previous studies focused on the removal of such compounds using oxidation, adsorption, and membrane-based treatments. However, these methods were not always efficient and formed toxic by-products. The impact of ion-exchange resin (IEX) (Purolite^®A502PS) was studied in a micro-filtration-IEX hybrid system to remove organics from ROC for varying doses of Purolite^® A502PS (5-20 g/L) at a flux of 36 L/m²h. The purolite particles in the membrane reactor reduced membrane fouling, evidenced by the reduction of transmembrane pressure (TMP), by pre-adsorbMembranesRemoval of Organics with Ion-Exchange Resins (IEX) from Reverse Osmosis Concentrate.PMC9967736776692Devaisy SAryal RJohir MAHRatnaweera HVigneswaran SKandasamy JfalseRemoval of Organics with Ion-Exchange Resins (IEX) from Reverse Osmosis Concentrate.Reverse osmosis concentrate (ROC) produced as the by-product of the reverse osmosis process consists of a high load of organics (macro and micro) that potentially cause eco-toxicological effects in the environment.
