ABSTRACT

The present study aims to evaluate the waste water management system in Jeedimetla effluent treatment plant limited, Hyderabad. Industrial Estates have become common feature of global landscape. Industrialization and pollution are like two side of the same coin. The goods and services are the result of Industrialization, which leads to the pollution of water, air and other natural resources. So, the need for treatment of waste water is utmost important in the environment perspective. Industrial waste contains toxic compounds have their own adverse effects which in turn effects ground water, which stimulates the growth of aquatic flora and fauna. So, the Effluent released from the industries cannot be directly disposed onto the land, they need some treatment before disposal to avoid contamination of soil, ground water etc.., that contain unacceptable amounts of suspended solids, dissolved solids, minerals etc.., which are dangerous when disposed without treatment.

INTRODUCTION

Developing countries have poor waste water management water is returned to the Surface water body directly without an adequate treatment, leading to reduction of the water quality and deterioration of the environment . Rapid industrialization is adversely impacting the environment globally. Pollution by in appropriate management of industrial wastewater is one of the major problems in India . Water crisis has global concern due to rapid industrialization and urbanization in the past few decades. Water is a vital necessity that all people need in order to survive .There are both supply –side threats and demands-side threats to water necessary to meet human needs. The number of estates has increased dramatically in the more developed countries and especially in the rapidly industrializing countries of Asia. Industrialization and pollution are like two side of the same coin. The goods and services are the result of Industrialization, which leads to the pollution of water, air and other natural resources. So, the need for treatment of waste water is utmost important in the environment perspective. Industries consume large amount of water for their process but only a fraction of water is used in the process. The rest finds its way into the drain as waste water. If this untreated water is allowed to accumulate it causes the decomposition of organic material thus leading to the production of large quantities of harmful gases. Industrial waste contains toxic compounds have their own adverse effects which in turn effects ground water, which stimulates the growth of aquatic flora and fauna. So, the Effluent released from the industries cannot be directly disposed onto the land, they need some treatment before disposal to avoid contamination of soil, ground water etc.., that contain unacceptable amounts of suspended solids, dissolved solids, minerals etc.., which are dangerous when disposed without treatment.

To address the issue of pollution coming out from industries, adoption of cleaner production technologies and waste minimization initiatives are being encouraged . Most of the small and some medium scale industrial units cannot afford to set-up their own effluent treatment plants to meet the prescribed pollution control norms. This has been become responsible to originate the concept of common effluent treatment plant (CETP). The concept of effluent treatment, by means of a collective effort, has assumed reasonable gravity by being especially purposeful for cluster of small scale industrial units. Common effluent treatment plant not only help in the industries in easier control pollution ,but also act as step towards cleaner environment and service to the society at large. Waste water of individual industries often contain significant concentration of pollutants; and to reduce them by individual treatment provides a better and economical option because of the equalization and neutralization taking place in CETP. In this over all country wise different effluent treatment plants were established

CETP (Common Effluent Treatment Plant) and its Concept

CETP was originally promoted by the Ministry of Environment and Forests (MoEF) in 1984 for the purpose of waste water treatment from a large number of small and medium scale industries . Common effluent treatment plant is considered as one of the viable means for small to medium enterprises for having effective waste water treatment solution.

CETP (Common Effluent Treatment Plant) is the concept of treating effluents by means of a collective effort mainly for a cluster of small scale industry units. The main objective of CETP is to reduce the treatment cost for individual units while protecting the environment .

CETP is adoptable to achieve economies of scale in waste treatment, thereby reducing the cost pollution abatement for individual factory. To minimize the problem of lack of technical assistance and trained personal as fewer plants require fewer people. It reduces the problems of monitoring for the pollution control boards and to organize the disposal of treated wastes and sludge and to improve the recycling and reuse possibilities .

CETP provides different advantages like savings in capital and operating cost of treatment plant. It offers economies of scale in waste treatment thereby reducing the cost of pollution abatement for each individual factory of industrial cluster; minimizes the problem of lack of trained personnel related to treatment plant expertise; solves the problem of lack of space to be allocated for treatment facilities and monitoring problems are also reduced . Combined treatment is always cheaper than small scattered treatment units. The neutralization and equalization of heterogeneous waste makes its treatment techno-economically viable. Disposal of treated waste water & sludge becomes more organized. It also reduces the burden of various regulatory authorities in ensuring pollution control requirement .

AIM AND SCOPE OF THE RESEARCH STUDY

Aim of this research study has been set to focus on the cost analysis, design and performance aspects of waste water or common effluent treatment plant. Common Effluent Treatment Plant related effluents are relevant point sources for residues of these compounds in the aquatic environment . However the scope of the research study has been limited to present the evaluation of performance of CETP from the perspective of treatment processes and its efficiency in terms of process indicator values of physical, chemical and biological properties.

PERFORMANCE EVALUATION OF TREATMENT PROCESS

Performance evaluation of the actual treatment system process for a CETP involves physical, chemical and biological treatments. Physical treatment mainly separates solids from the waste water using mechanical screens, sedimentation and flotation, most chemical treatment of waste water involves the use of chemical to remove specific wastewater constituents. Preliminary treatment, primary treatment processes are mainly physical. Chemical treatment methods include neutralization to maintain optimum pH for biological treatment processes, precipitation reactions for removal of dissolved solids and phosphorus and Oxidation (chlorination, ozonation, ultraviolet radiation) for disinfection and odor control. Biological treatment processes are used primarily for secondary treatment and use microbial action to decompose suspended and dissolved organic matter in wastewater. Biological treatment processes include natural methods and engineered methods. Generally, industrial waste waters from manufacturing have lower BOD: COD ratios and higher levels of toxic substances

RESULTS & DISCUSSIONS

In the present study water samples were analyzed and the wastewater results are confirmed that all the results of parameters are within the standards after the treatment. So with the help of different treatment methods pollution levels can be decreased so with the more effective effluent treatment methods have to use in water treatment. Quantity and quality are two major issues involved in the use of water. The main purpose of analyzing physical and chemical characteristics of water is determining its ecological status. The physic-chemical parameters such as temperature, pH, Dissolved Oxygen, organic, inorganic constituents’ play an important role in determining water quality, nature of water sample and it is also the prime considerations to accesses water quality. In present study total samples were collected at 14 places in effluent treatment plant, results are compared with standard results

CONCLUSION

The major environmental concern is an urbanizing India relate to high levels of water pollution due to poor waste disposal, inadequate sewerage and drainage, and improper disposal of industrial effluents. The CETP (Common Effluent Treatment Plant) has been modified to operate as the first combined waste water treatment plant (CETP) in India treating industrial waste along with domestic sewage. It is successful in its treatment. The process achieves greater than 95% BOD removal and maintains low BOD to COD ratio. Operation and maintenance in the plant is maintained strictly and also follows all the safety rules. Each and every treatment unit as per the design requirements and also can accommodate future inflow.
