Different Methods of Industrial Wastewater Treatment

Industrial Wastewater Treatment

Abstract

Industrial wastewater coming from numerous industries is the major source of water pollution. Wastewater contains heavy metals, organic and inorganic contaminants, and insoluble materials. This contaminant poses a serious hazard to the environment. Removal of these pollutants requires innovative and novel methods and technologies. The treatment of wastewater can be done in a variety of ways. There are several techniques available, including adsorption, coagulation, and activated sludge. Water treatment also uses inexpensive adsorbents. A number of Nano-materials have been considered for use as potential pollutant removal candidates in recent years. For elimination of heavy metal, conventional methods include chemical precipitation, ion exchange, adsorption, the ion floatation, electrochemistry as well as coagulation/flocculation. Despite these advantages, however, these methods have some serious disadvantages. In addition to photo catalysis, electro dialysis, and membrane separation techniques, new adsorbents have been introduced to improve adsorption. Fenton processes for treating real industrial wastewater are critically reviewed in this article. To reduce contaminants in wastewater, this paper discusses possible wastewater treatment techniques.
