Eutrophication: Causes, consequences, physical, chemical and biological techniques for mitigation strategies

Eutrophication is reckoned as an ecological challenge that exhibits adverse effects on the aquatic ecosystem as well as the sustenance of portable water required by humans for their unremitting survival on the earth. There has been a range of techniques for the prevention of eutrophication, consequent on the need for the provision of portable water and the protection of water bodies and the aquatic ecosystem. The employment of chemical coagulants such as lime, magnesium sulphate and ferric sulphate has been reported to yield more than 95% removal of nitrate and phosphate. Moreover, adsorption studies revealed that at optimum pH and a contact time of 60 min, glutaraldehyde cross-linked chitosan exhibited the…
