| Summary: | In recent years, photocatalytic treatment of palm oil mill secondary mill effluent (POMSE) incorporating ZnO nanoparticles with various types of capping agents via membrane photocatalytic reactor (MPR) has gained great
interest among researchers. Nevertheless, most of previous studies have employed a rather time-consuming oven
drying and calcination method to synthesise ZnO in powder form. Therefore, a simpler synthesis method is considered necessary. In this study, ZnO-clay was synthesised in liquid form using the precipitation method, without undergoing oven drying and calcination. The effect of different ZnO-clay ratios on the degradation performance of POMSE via MPR was also examined. Results indicated that ZnO-clay 1:3 was efficient in BOD removal percentage, while the removal percentages of COD, colour and turbidity were higher for ZnO-clay 1:5 compared to other ratios. |
