ABSTRACT

J. Tong et al. propose that effluents from the paper and pulp industry, coal manufacturing facilities, petrochemicals, textiles, and the pharmaceutical industry influence the most out of the other sectors in terms of health hazards. Highly toxic effluents are being generated by these industries. The complex nature of the effluent makes the treatment process more expensive. A thorough understanding of the treatment technologies used to treat these industrial effluents is particularly of high priority to alleviate environmental concerns. The fatality induced to aquatic life by the paper and pulp mill effluents due to the disruption of carbohydrate metabolism, ion balance as well as enzyme’s biotransformation activity has been studied by many researchers. Petrochemical industry effluents, on the other hand, can cause mutagenicity to even the purest forms of water bodies. Out of the several treatment methods that have been tested for overcoming this issue, ozonation has been the most widely reported treatment technique.
