“…The term of river bank filtration (RBF) was first developed in Germany and has been used in many parts of the world for public and industrial water supply over 100 years [9,10]. RBF can occur under natural conditions or may be induced by lowering the groundwater table below the surface water level via abstraction from adjacent boreholes [11].…”

Municipal wastewater reclamation and reuse has been an effective way to solve problems of shrinkage and drying up of rivers and lakes. The residual pollutants in recycled water may pose a risk to groundwater. A field study on the spatial and temporal variations concentrations of nitrate, ammonia and chemical oxygen demand (COD) was conducted in Beijing, where recycled water is used to recharge dry rivers. And the effect of a riverbank filtration (RBF) on the nitrogen and organics removal from the Qingyang River was investigated. Water samples from recycled water, river water and groundwater were collected for nitrate, ammonia and COD measurement. The results indicated that river water quality was improved when recycled water was refilled to the river course. The concentration of nitrogen and total phosphorus decreased along the flow directions in the Qingyang River. Higher temperature in summer can promote nitrogen and COD removal in the river. The results indicate that about 63%, 89% and 41% of nitrate, ammonia and COD was removed from the river bank filtration. These results indicate that improving the removal of nitrogen and organics in recycled water and optimizing the management of recharging operation could reduce the risks of nitrogen and organics.

“…Also, banks have much higher variability in their composition (usually have a significant amount of coarse grains) than in the plains. In mountainous regions of India, particularly Himalayas, river/lake waters are cleaner in terms of organics and coliforms [20]. However, turbidity varies widely from non-monsoon to monsoon seasons.…”

Riverbank filtration leads to purification of water. For India it can be a simple, economical and effective alternative. A few unanswered questions were: Can it work in Indian mountainous regions? Will it be of any advantage in the case of some of the polluted Indian surface waters? With the goal to evaluate use of riverbank filtration as a sustainable technology under widely varying conditions prevalent in India, the effectiveness of riverbank filtration has been examined over the last 10 years. In the case of cleaner surface waters, the wells deliver water free of turbidity and coliform even during monsoon irrespective of well configuration. In the case of polluted source waters, it results in an overall advantage in terms of improved raw water quality, reduced degree and cost of subsequent treatment and decreased levels of disinfection by-products. The study shows riverbank filtration to be an effective and sustainable option for plains as well as the mountainous region.
