sources such as domestic wastes, agricultural activities, leachates from solid waste dumps, and industrial effluents among others. According to UN estimates, the total annual amount of produced wastewater is approximately 15x106m3, which is six times .
The toxic heavy metal ions which pose potential danger from the industrial waste waters include lead, mercury, copper, cadmium, zinc and nickel. Precipitation, ionexchange, evaporation, reverse osmosis, electrodialysis, adsorption by activated carbon and clays, solvent extraction and cementation are some of the techniques that have been used for removing heavy metal ions .
· Wastewater is produced from various industrial processes such as mining, power generation, petroleum refineries, breweries, dairy processing, chemical production, food production and many more. Most industries are now required to treat their wastewater on site before it is discharged to river or sewer (to meet a discharge consent limit), but this treatment .

· 2 Reuse of Treated Effluent Reuse of treated wastewater in various industries is becoming very popular being a cheaper source of water supply where the industrial plant can reuse its own wastewater through recycling or after treatment or it can be used for irrigation. There are many possibilities that some of hazardous and toxic chemicals may pass to the treated effluents.
Not the clouds touching Ganga, but industrial effluents floating on Her surface. 764 industries in the main stream of the Ganga, including Kali and Ramganga, consume 1123 MLD water and discharge 500MLD waste water. 2.

3 Wastewater: is simply that part of the water supply to the community or to the industry which has been used for different purposes and has been mixed with solids either suspended or dissolved. Wastewater is % water and % solids.
refining industries dominate the use of fossil fuels for boiler operation, while the primary metals, chemicals, and petroleum refining industries dominate the use of fossil fuels for process heating equipment (EIA 2002). Process heating equipment and boilers release mediumtohigh temperature exhaust gases, waste steam, and effluents.
Discharge from industry contains various organic and inorganic pollutants. Among these pollutants are heavy metals which can be toxic and/or carcinogenic and which are harmful to humans and other living species (MacCarthy et al. 1993; Clement et al. 1995; Renge et al. 2012).The heavy metals of most concern from various industries include lead (Pb), zinc (Zn), copper (Cu), arsenic (As), cadmium ...

effluents from industries are varied and industry specific. Phiri et al., (2005) noted that the careless disposal of industrial effluents and other wastes may contribute greatly to water pollution. Most of the water bodies in the areas of the developing world are the end points of effluents discharged from industries.
