Design and Operational Aspects of Common Effluent Treatment Plant in GIDA Project Area of Gorakhpur (U. P.),
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 3
Abstract
In order to minimize environmental pollution due to the small and medium-scale industries, cleaner production technologies and waste minimization are being encouraged in India. 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 Project Area. However, most of the units, being small scale industries, do not have their wastewater treatment units. Besides, there is no satisfactory arrangement of wastewater treatment in large scale industries also, even though they have established their own Effluent Treatment Plants (ETP‟s). This is a major cause of pollution of Ami River in the region. In this paper, the design and operational aspects of a Common Effluent Treatment Plant (CETP) for large scale industries belonging to textile sector namely, M/s Lari Textiles and Dyeing Ltd., M/s Ambey Processors and M/s Bathwal Udyog Pvt. Ltd. worked out. The design parameters have been looked into and the quantitative and qualitative aspects of effluent treatment required by CETP are also studied. The analysis of operational cost of various CETP technologies has been carried out and the comparisons are made on the basis of life cycle cost analysis of 30 years. It is revealed that the combination of UASB reactor and Facultative Waste Stabilization Pond ((FPU)) is the least cost feasible treatment technology for CETP. Accordingly, the sizing parameters of UASB reactor and Facultative Waste Stabilization Pond (FPU) are worked out and the annual saving in cost by energy recovery through biogas generation is found out. It is expected that the establishment of CETP in GIDA Project Area will be a step forward towards environmental protection and would go a long way in saving Ami River from the adverse effects of industrial pollution.
