T. University Gorakhpur, INDIA Email:amitc1566@gmail.com 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 of Ami River in the region. In the present study, of wastewater characterizes of 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 wastewater characteristics parameters have been looked into the quantitative and qualitative aspects of effluent treatment required by CETP are also studied. Wastewater characteristics in GIDA Industrial 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. Key words: Biochemical oxygen demand (BOD), Chemical oxygen demand (COD), Effluent generating industries. 1. INTRODUCTION 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. Accordingly the ministry of environment and forests instructed various states each industrial unit to provide and operate individual wastewater treatment plant because of the scale of operations or lack of space or technical manpower. However, the quantum of pollutants emitted by SSIs clusters may be more than an equivalent large scale industry, since the specific rate of generation of pollutants is generally higher because of the inefficient production technologies adopted by SSIs. 2. Sample Collection Out of 159 industrial units in GIDA Industrial Area, 154 units are small-scale industries and 5 units are large-scale units. The large scale units are: 1. M/s Ambey Processors 2. M/s Bathwal Udyog Pvt. Ltd. 3. M/s Lari Textiles and Dyeing Industries Pvt. Ltd. M/s 4. India Glycols Ltd. 5. M/s Gallant Steel Ltd. It is realized that M/s India Glycols Ltd. is required by Central Pollution Control Board, Delhi to follow zero liquid discharge and the onus lies on the part of the industry. M/s Gallant Steel Ltd. is distantly located from the nest of the agglomeration of industrial units in GIDA Industrial Area as such it has to take up its own treatment mechanism. However, M/s
