The purpose of this project is to prepare a cheap, cost efficient, simple, affordable and sustainable treatment of grey water for household purposes. Activated charcoal and sand filters were evaluated for the purpose of grey water filtration. The treated grey water can be used for non-potable purposes such as irrigation, car washing, urinals and toilet flushing, fire protection, etc. To achieve this objective samples were collected from households and series were collected from households and series of treatments such as pH, TDS, Alkalinity, BOD, COD were carried out. We have compared the results of effluent (chemical and physical properties) from slow sand filtration and slow sand filtration aided with Activated Charcoal filter. Thus, from the results an attempt has been made to prepare a household model for the treatment of Grey water by using activated charcoal and then reusing it for various purposes. This project will help to understand a new approach of an environmental friendly household filtration techniques.
