Applications of Fenton Coagulation for wastewater treatment: a review

Abstract

The most diverse forms of pollution and contamination, especially from the industrial sector, reinforce the need to optimize industrial processes in the search for reducing waste generated or even creating and improving appropriate techniques for removing organic compounds in solid waste and effluents. Wastewater resulting from chemical processes, in general, has a complex composition and causes environmental problems when not treated appropriately. An efficient proposal for the treatment of effluents of high chemical complexity and high concentration of suspended solids is Fenton Coagulation. This process reconciles the coagulation process with iron ions and reuses the residual iron concentration to apply a subsequent treatment, the Fenton process. Therefore, the objective of this work is to address the hybrid Fenton coagulation process and discuss important aspects of its use for the treatment of effluents.
