Persistent Organic Pollutants in Water and their Microalgae Based Bioremediation

ABSTRACT: This appraisal overviews Persistent Organic Pollutants and suggests a novel approach to their bioremediation using algae as an agent. Compared to older techniques using different bacteria, a greenway for wastewater treatment is more environmentally sustainable and friendlier. It has a lot of potential to use new bioremediation technology that uses cyanobacteria and algae to remove variety of organic pollutants. Several organisms' health and well-being may be at risk due to the abundance of organic pollutants in the environment. Household garbage, agriculture, and industry are some of the numerous man-caused contributors to organic pollutants that pollute water across the planet. Wastewater needs to be cleaned before it may be discharged into rivers. As algae-based wastewater treatment systems don't produce any secondary pollutants and are environmentally sustainable, they are growing in popularity. A variety of organic pollutants can be absorbed and accumulated by algae and cyanobacteria at different rates, contingent upon the type of contaminant, the physio-chemical assets of waste water, as well as the specific species of algae involved. Moreover, phytoremediation is a more affordable option for breaking down organic pollutants than traditional methods. Algal biomass produced through phycoremediation might also play a significant role in the bioenergy value chain. Hence the emphasis of this paper is on an over view of Persistent Organic Pollutants, cyanobacteria and microalgae species, which have the potential to rid water systems of several organic pollutants.
