摘要：The vast and rapid development of industries has lead to destruction of nature. Sources of nature like the water, air, soil, etc are being invariably polluted due to these industries. The release of toxic compounds from the various industries like the leather, chemical, pharmaceutical, steel, textile, food, play a major role in the nature imbalance. Pretreatment process step makes the initial purification easier and faster. This paper showcases the processing and effects of effluent released along with the initial treatment of the effluent, the pretreatment using alum, polyvinyl alcohol, and dolomite.
