Evaluation of vermifiltration process using activated charcoal for effective sewage water treatment

India is rich in water resources, having a network of as many as 113 rivers and vast alluvial basins to hold plenty of ground water. But due to tremendous increase in the demand of water due to increase in population as well as the deterioration of available water, it has now become the necessity to find ways to reuse the available water. Hence it becomes important to find ways to treat the available polluted water in the simplest way for the benefit of mankind. In this work, evaluation of vermifiltration using different natural ingredients and activated charcoal is done. Activated charcoal is used as natural Ingredient employing Eisenia Fetida (Earthworm species) to filter sewage waste water. The whole investigation was carried out for 90 days and the filtrated water was tested for various critical parameters namely, pH, removal efficiency of BOD, COD, Total dissolved solids, Total suspended solids, Turbidity, Odour, Colour, Nitrate, Chlorine. The aim of this review is to evaluate the performance of vermifilter using activated charcoal.
