ABSTRACT

The semiconductor industry is considered as one of the largest industries in the world, which has a production value of approximately US$400 billion. Wastewater from semiconductor industry usually contains a wide range of harmful contaminants, such as solvents, arsenic, antimony, acids, alkalis, salts, fine oxide particles, and other pure organic and inorganic compounds. Since, environmental protection and sustainable development have become a critical concern due to which the semiconductor industry has gradually adopted sustainability considerations. The Some companies have proactively solved the challenges and mitigated related risks by reducing their reliance on chemicals and improving the treatment of water before discharge. More than 200 high-purity organic and inorganic compounds are used in the manufacturing processes of semiconductor industry. Chemical mechanical polishing wastewater effluents invariably contain significant amounts of organic compounds as well, as reflected by their chemical oxygen demand concentration as high as 500 mg/L.
