  • Ultrafiltration in Water and Wastewater Treatment

    2015-10-9 · In the beginning, most application of ultrafiltration is in medical sector, i.e., kidney dialysis operations. Nowadays, ultrafiltration is applied in wide variety of fields, from food and beverage industries to chemical industries. Water and wastewater treatment are also the potential field of ultrafiltration application. Today, UF technology is being used worldwide for treating various water sources. The use of UF technology for municipal drinking water applications is a relatively recent concept, although as mentioned before, it is commonly used in many industrial applications such as food or pharmaceutical industries [Laîné, et. al. 2000]. The recent global increase in the use of membranes in water application is attributed to several factors, i.e., increased regulatory pressure to provide better treatment for water, increased demand for water requiring exploitation of water resources of lower quality than those relied upon previously, and market forces surrounding the development and commercialization of the membrane technologies as well as the water industries themselves [Mallevialle, et. al. 1996]. In this paper, the application of ultrafiltration in water treatment, the system …
