Evaluation of polymeric adsorbents via fixed-bed columns for emulsified oil removal from industrial wastewater

Polymeric adsorbents (PAs) have been gaining increased attention for application in industrial wastewater (WW) treatment. However, most studies on evaluating PAs specifically emulsified oil removal are currently limited to performance screening through batch mode testing. Hence, this paper presents a thorough fixed-bed assessment of advanced the from WWs. A unique custom-built column setup was developed with continuous test protocol that involves both adsorption and regeneration media. robust procedure also established automatically prepare representative synthetic produced water (PW) containing oil-water emulsions. Four cutting-edge were evaluated, out which two being tested first time targeting removal. Experimental tests conducted address resin capacity, efficiency, reproducibility repeat cycles. PA2 treated 168 ± 58 bed volumes (BVs) achieving lowest capacity 44 14 mg/g. Higher comparable capacities observed PA1 PA3 at ~100 mg/g, yet found capable treating 807 3 BVs against 548 115 measured PA3. PA4 1219 86 301 27 mg/g indicate its strong potential WW treatment application. This data can provide reference comparison when testing other novel resins Future will focus using real PW their long-term via pilot
