Electrochemical Coagulation of Wastewater Containing Persistent Organic Pollutants
https://doi.org/10.18412/1816-0395-2026-4-24-29
Abstract
The regularities of electrochemical formation of ferrous and ferric hydroxide hydrates, their properties, and the efficiency of their application in the process of electrocoagulation for the treatment of wastewater containing persistent organic pollutants (POPs) were investigated. The results of studying the formation domains of ferrous and ferric hydroxide hydrates as a function of pH are presented. The influence of the following factors on the electrochemical generation of iron ions was established: specific electrical resistance of water, the presence of POPs in water in the form of anionic and nonionic surfactants. Recommended values of process parameters of electrochemical coagulation are determined-specific yield of iron ions, anodic current density, and degree of POP removal-with reference to wastewater from dyeing and finishing enterprises of the light industry.
