Abstract

Industrial sector is a backbone of the economy throughout the world. Despite that there are a lot of benefits; such as development of urbanization, major contributor in economy’s growth is sign of industrial development. There are a lot of adverse effects on environment including depletion and damage of our natural and precious resources. Textile, cement, paper and pulp, sugarcane, food, pharmaceuticals, chemical, paint and other industries are largest consumers of the freshwater; for meeting the requirements of industrial production requirement for the industrial sector for their production. As a result the discharged huge amount of water in form of highly polluted water, this is a great threat to our ecosystem. The unplanned industrialization is a prime responsible for degradation of environment. If industrial wastewater is not properly treated instantly, it may create foulest and septic conditions in adjacent parts of the industrial areas. The discharges acute poisonous wastewater by different industries is responsible for reduction of penetration in crops, and severely affects aquatic life. There are many treatment techniques such as coagulation, adsorption, membrane, biological etc. by different research studies disclosed that coagulation with different chemicals alum, ferric chloride, lime, PACl, PVA and ferrous sulphate are very effective for remove of pollution. The industrial wastewater creates several problems such as health problems, aquatic life including water pollution. In this paper reviews the chemical coagulation treatment technologies for industrial wastewater.
