Remediation methods for the removal of pesticides in wastewater

Abstract

This work is part of one of the priorities of sustainable development that is the conservation of soil and the care of aquifers. Water is a vital liquid for human and all kind of living beings, the presence of pesticides in drinking water is a health problem that requires solution. In this paper, a review of the different methods used for the removal of pesticides in wastewater is made, such as biological remediation methods, using plants and microorganisms, remediation by physical methods by adsorption of contaminants with activated carbon, zeolites, polymers and clays and finally chemical remediation, through advanced oxidation with the production of hydroxyl radicals. A review of the most commonly used pesticides in the different agricultural areas is carried out, as well as their impact on the health of the inhabitants in these regions. Finally, a comparison of the advantages and disadvantages of these methods is made both for its effectiveness as well as for their cost.
