Deployment of Solar Energy in Reconditioning the Grey Water

The applicability and efficiency of solar energy in the treatment of Grey water (Sullage water) was investigated. The study reveals about the comparison of standard water quality parameters with grey water treated by harnessing the solar energy. The core objective of this paper aims in treating the grey water at low cost by designing and experimenting a lab scale solar distillation unit. Initially the grey water was collected from a domestic house drain (100 litres approximately) and preserved under laboratory condition. In parallel two solar distillation units (with and without Fresnel lenses (FL) arrangements) was designed and constructed to treat the collected grey water. The tests were performed under three different conditions by filling 25%, 50% and 100% of grew water (by volume) in the solar distillation units. A comparison was made to assess the performance of Solar Distillation Units (SDU). Results revel that the SDU aided with FL perform better than the one without FL arrangement.
