Factor Embedded To Improve the Efficiency of Cooling Tower

Ankit Manral & Vijay Chaudhary

ABSTRACT- Cooling towers was originated out of the development in the 19th century of condensers for use with the steam engine. Condensers use relatively cool water, via various means, to condense the steam coming out of the pistons or turbines By the turn of the 20th century, several evaporative methods of recycling cooling water were in use in areas without a suitable water supply, such as urban locations relying on municipal water mains. In areas with available land, the systems took the form of cooling ponds; in areas with limited land, such as in cities, it took the form of cooling towers. Common applications for cooling towers are providing cooled water for air-conditioning, manufacturing and electric power generation.....>> Read More

Industrial Wastewater Characteristics in GIDA Project Area of Gorakhpur, (U.P.)Amit Prakash Choudhary

ABSTRACT- In order to minimize environmental pollution due to the small and medium-scale industries, cleaner production technologies and formation of waste minimization circles are being encouraged in India. Besides, collective treatment at a centralized facility, known as the CETP, is considered as a viable treatment solution, to overcome the constraints associated with effluent treatment in small to medium enterprises. Ever since the inception of Gorakhpur Industrial Development Authority (GIDA) in 1989, some 159 industries have come up in GIDA. However, most of the units being small scale industries do not have their waste water units. Besides, there is no satisfactory arrangement of wastewater treatment in large scale industries also, even though they have established their own Effluent Treatment Plant (ETP). This is a major cause of pollution.....>> Read More
