Industrial Waste Water Treatment Using Natural Filtration and Solar Distillation Methods

Abstract

The need of fresh water is vital for human survival and fulfillment of demand has become serious concern in countries having limited water resources. Large amount of water from industries is wasted daily all over the world, which can be reused by proper water treatment. This present work discusses the methods of waste water treatment using filtration and solar distillation methodology. The samples of industrial waste water were collected from chemical and fertilizer industry in Kota, Rajasthan. The pH, TDS and dissolved oxygen values of waste water samples and water after treatment was tested and results of different waste water samples are reported. Ammonia, cement and carbide waste water samples having TDS 310,510 and 268 PPM were treated using filtration and solar distillation methods. The treated water after filtration had TDS 274,460 and 208 PPM respectively. The treated water after solar distillation had TDS 107, 288 and 98 PPM. The obtained values of TDS, pH, and dissolved oxygen after combined treatment of filtration and distillation are close to standard values required for potable water.
