A Comparative Study of the Prameters in the Industrial Effluent in Trichy Region

Abstract

For many years, many industries like chemical industries,
refineries etc. employed various chemical treatments along with
water. After processing, the effluents are discharged. The influence
of these effluents on human health has been undertaken on a large
scale in our country and are controlled by environment bodies. Six
different water samples of Trichy region were analysed. This work
includes all aspects of the treatment of effluents arising from various
branches of various industries. In sympathy with modern legislative
trends, the emphasis is one means of avoiding or at least minimising
the pollutants present in the effluent. The results obtained and discussed
herein suggest that water from various industries which
contains relatively low hardness (total, temporary and premanent
hardness) and low pH values with acceptable limits. The present
study has been done to compare the parameters for combined,
treated effluents in winter and rainy season and biodegradability in
winter season.
