Impact of treated paper mill effluent irrigation on quality of soil and ground water

摘要

The paper and pulp industry is classified as a highly water intensive one and it also forms a major polluter of soil and water resources. In order to utilize the enormous quantity of treated effluent, the bagasse based paper mill has established an Treated Effluent Water Lift Irrigation Society (TEWLIS) and has continously used the treated effluent water in the erstwhile drylands of rainfed regions in Pugalur taluk of Karur district, Tamil Nadu for agriculture since 1994. The treated paper mill effluent contains nutrients that enhance the plant growth but also has other toxic materials too.
