Assessment of river water quality improvement due to riverbank filtration (RBF) mechanism

Abstract Riverbank filtration (RBF) is a natural process where river water induced to flow through riverbed soils pumping wells located on the banks. It well-established and proven treatment technology by having series of physical chemical processes during subsurface passage. This paper aims at measurement characteristics groundwater from riverbank Kg. Jenderam Hilir, Selangor assess effectiveness Water Quality Index (WQI) for both groundwater. The able improve quality such as reducing turbidity 0 NTU, Chemical Oxygen Demand (COD) 3.67 mg/l, Suspended Solids (SS) 6.33 mg/l several other contents that existed in river. In addition, RBF also based improvement Langat Class IV III.
