Malaysia's largest river bank filtration and ultrafiltration systems for municipal drinking water production

This paper presents a case study of Wakaf Bunut water treatment plant (the ‘plant’) in Kelantan, Malaysia. The plant was successfully commissioned in February 2013 and started operating in March 2013. It is capable of supplying up to 14 million liters a day of potable water to Tok Bali. Feasibility studies were carried out on the combination of river bank filtration (RBF) and ultrafiltration (UF) to reduce operating costs while maintaining filtrate quality. The plant is the largest municipal drinking water treatment plant in Malaysia using combined RBF and UF technologies. Actual operating data from the plant were collected and are discussed in this paper.
