Abstract: 
Every year, a massive amount of wastewater is discharged into water bodies from various industries, and numerous processes are used to treat wastewater to reduce the number of pollutants. Industrial wastewater can be very different from sewage in terms of its discharge patterns and compositions. The overall scenario is not different for Bangladesh a developing country. Hence, the industrial wastewater treatment process has undergone modification as time passes newly discovered dangerous substances in the industrial wastewater treatment process worldwide. Multiple methods including conventional and advanced methods are upheld in this present paper with advantages and disadvantages also illustrated there. Besides, the potential for integrating two or more technologies to enhance treatment efficiency is also addressed. Considering low cost as well as maintenance purposes, among all the methods, hybrid or integrated technologies are found effective to reduce the contamination level of wastewater.
