Abstract

The goal of this paper is to examine the potential for ecologically and economically sustainable to chemical processing including textile processing. This paper reviews technical and scientific literature on a wide range of factors that will influence the overall impact of discharge done by the various chemical processors (textile, paper, wood-pulp etc.) on its total environment. The emphasis is on efforts to achieve "Zero Discharge or Totally Effluent Free (TEF) mills. The chemical processing industry is one of those identified as a potential threat to the environment due to the discharge of toxic effluents that cause air, water and soil pollution.

Zero discharge system is meant to treat all the incoming effluent, leave nothing behind. However, practically this is not feasible since some waste is always generated in the treatment process. Therefore, the main aim is to recover usable materials such as water and salt from the effluent, and; minimize the generation of waste so that it can be safely stored on-site without the need for discharge into the environment.

Introduction

Till recently the objective of a textile wet processor was to administer the desired colour and finish to the textile material with scant regard to the environment. These days awareness of the need for protecting the environment has posed challenging problems to all the industries causing environmental pollution. The textile wet processing industry is one of those identified as a potential threat to the environment due to the discharge of toxic effluents that cause air, water and soil pollution.

These pollutants when discharged untreated pose a great threat to human health, aquatic life and vegetation. These problems may be minimized only if the effluent generated in a process house is reduced to the minimum possible level. So today the textile wet processors also realized about the characteristics of the effluent that they discharge out of their units and its impact on the ecology. So the Chemical & textile wet processors are implementing effective measures to control the generation of waste not only at the production stage but also in tackling the disposal or treatment of effluent
