Abstract

Riverbank filtration system is a technique used for surface water treatment that is based on biological activities to attenuate the contamination in water through its movement from the river to the adjacent pumping well. Hydraulic conductivity is a critical parameter that affects the efficiency of riverbank filtration systems. In this study, an analytical model, using Green’s function approach, is developed to investigate the effect of hydraulic conductivity on contaminant transport and RBF system efficiency. The model is applied at the RBF site in Malaysia. The outcomes show that increasing the hydraulic conductivity values results in lowering the quality of the pumped water produced from the well, in which the contamination area around the well increase. Additionally, the distance from well to the river that should be considered when establishing a new RBF site is significantly affected by the hydraulic conductivity value.

导电性对河岸过滤系统中三维污染物运移的影响

河岸过滤系统是一种用于地表水处理的技术，它是基于生物活性来减少水中的污染，通过它从河流流向邻近的抽水井。导流率是影响河岸过滤系统效率的关键参数。在本研究中，采用格林函数方法建立了一个分析模型，以研究水力传导性对污染物输送和RBF系统效率的影响。该模型在马来西亚RBF现场得到了应用。结果表明:导水系数值的增大导致抽油井产出水水质的降低，井周污染面积增大;此外，在建立新的RBF站点时应考虑的井到河流的距离受水力导率值的显著影响。

期刊介绍： Asia, as a whole region, faces severe stress on water availability, primarily due to high population density. Many regions of the continent face severe problems of water pollution on local as well as regional scale and these have to be tackled with a pan-Asian approach. However, the available literature on the subject is generally based on research done in Europe and North America. Therefore, there is an urgent and strong need for an Asian journal with its focus on the region and wherein the region specific problems are addressed in an intelligent manner. In Asia, besides water, there are several other issues related to environment, such as; global warming and its impact; intense land/use and shifting pattern of agriculture; issues related to fertilizer applications and pesticide residues in soil and water; and solid and liquid waste management particularly in industrial and urban areas. Asia is also a region with intense mining activities whereby serious environmental problems related to land/use, loss of top soil, water pollution and acid mine drainage are faced by various communities. Essentially, Asians are confronted with environmental problems on many fronts. Many pressing issues in the region interlink various aspects of environmental problems faced by population in this densely habited region in the world. Pollution is one such serious issue for many countries since there are many transnational water bodies that spread the pollutants across the entire region. Water, environment and pollution together constitute a three axial problem that all concerned people in the region would like to focus on.
