RIVER BANK FILTRATION - A NATURAL AND ECONOMICAL WATER TREATMENT TECHNOLOGY

River Bank Filtration is a water treatment technique that consists of bring out water from river by pumping wells located in the nearby aquifer. It is the technique of Aquifer Recharge in which the surface water treated through the aquifer medium. In present study an attempt is made to understand the impact of River Bank Filtration on surface water, in Jabalpur city in Madhya Pradesh. The geological conditions, well types, cost saving on coagulant and the physical, chemical and biological effect of RBF were discussed in this study. Chemical coagulants are costly because of this it is becoming difficult day by day to run the treatment plant by using chemical coagulant, so RBF can be a good alternative pretreatment idea in the long run. It has been found that bank filtration works effectively as a natural treatment as well as alternative solution of pre-treatment. Turbidity removal efficiency of RBF was 94.22% in this study. Due to its efficiency, easiness and low-cost process River Bank Filtration will be a better and sustainable solution to partly fulfill the present water demand in India.
