Abstract

Ultrafiltration technology has long been utilized and largely applied in the pharmaceutical industry, in food and beverage processing, and in treating water because of its excellent performance. Although, a common limitation to a membrane’s performance is fouling, which is the permeate flux decline due to concentration polarization of foulants from the feed on the membrane’s surface. A new fouling problem emerges when the feed contains microorganisms (bacteria). The bacteria can cause biofouling, where adhered bacteria on the membrane’s surface are more difficult to remove due to their adhesive secretions. A way to reduce biofouling is the incorporation of antibacterial additives to the membrane, through surface modification or embedding the additives into the membrane matrix. The modified membranes are proven to have increased hydrophilicity and gained an antibacterial property, thus having an increased permeability and an amount reduction in adhered bacteria. The chances of biofouling were significantly lowered, and the overall membrane performance was enhanced. Despite the positive results, commercial antibacterial ultrafiltration membranes are not yet available as research on this topic is still new and ongoing. This review will discuss and summarize the effects of antibacterial additives on ultrafiltration membranes, using data from collected articles.
