Application of the ultrafiltration process in the treatment of brewery wastewater

The objective of this study is to evaluate the efficacy of UF treatment of brewery wastewater from a university brewery, employing flat polymer membranes with varying cut-offs. The findings provide substantiation for the viability of the examined UF process for the treatment of brewery wastewater. The study demonstrated that the separation properties of the membranes are contingent on their limiting resolution, with the XT membrane (1000 Da) yielding optimal results. Increasing the transmembrane pressure (TMP) did not yield a substantial enhancement in separation efficiency, particularly for mem- branes with larger pores. The UF efficiency demonstrated stability over the course of the study, thus suggesting that the membranes exhibited excellent resistance to blockage and did not necessitate frequent regeneration. The transport properties of UF membranes are contingent on TMP, cut-off value, and operating time. An increase in pressure and cut-off value increased permeate flux; however, the hydraulic capacity of the membranes gradually decreased over time.
