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

(Zero Discharge possible by hauling away waste cake and
sludge, if amount is small)
