Introduction The main sources of water pollution in India at present are city sewage, discharge of industrial wastage, intensive use of fertilizers, insecticides and pesticides in agriculture. Excessive use of fertilizers has increased the level of nitrates in shallow ground water sources. The nitrate content in well water in Mahendragarh district in Haryana was found to be as high as 1310 mg/L. In Howrah district, intensive agriculture has contributed to high levels of such pesticides as D...

The presence of very small amounts of dyes in water is highly visible and undesirable.1-2 Dyes may significantly affect photosynthetic activity of aquatic life due to reduced light penetration and may also be toxic to some aquatic life due to the presence of aromatics, metals, chlorides, etc. in them.3-6 Total dyes consumption of the textile industry ...
Introduction Heavy metal pollution is a threat to human health, animals and plants and is mainly caused by industrialization and its consequences (Park, et al., 2007). Among the various heavy metals, pollution by chromium and its compounds is of considerable concern. This metal is highly reactive and has found widespread use in leather tanning, electroplating, metal finishing and chromate preparation processes (Parvathi and Nagendran, 2007). So the removal of chromium metal from wastewater is...
Introduction Molasses (one of the important byproducts of sugar industry) is the chief source for the production of alcohol in distilleries by fermentation method. About 40 billion liters of waste water annually discharged in distilleries, known as raw spent wash (RSW), which is characterized by high biological oxygen demand (BOD: 5000-8000mg/l) and chemical oxygen demand (COD: 25000-30000mg/l) (Joshi,1994) , ugly color and bad smell. Discharge of raw spent wash into open land or near by wa...
Introduction The world is presently confronted with the twin crises of fossil fuel depletion and environmental degradation. Indiscriminate extraction and lavish consumption of fossil fuels have led to reduction in underground-based carbon resources. The search for alternative fuels, which promise a harmonious correlation with sustainable development, energy conservation, efficiency and environmental preservation, has become highly pronounced in present context. The fuels of bio-origin can p...
Introduction Vat dye is one of the important dyes used on the dyeing of cotton textiles due to its overall good fastness properties suitable for the end use products.¹ Vat dye has the problem of insolubility in water, but when reduced with a strong reducing agent like hydrose and solubilising agent sodium hydroxide, it is solubilized. The reduced dyestuff penetrates into the fiber and it is reoxidised on the fiber back to the insoluble form, which remains fixed in the fabr...
Introduction The sources of drinking water (both tap and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over surface of the band or through the ground, it dissolves naturally-occurring minerals and in some cases radioactive materials and pick up substances resulting from the presence of animals or from human activity.1 Contaminants that may present in source water include viruses and bacteria, which may come from sewage treatm...
