ELECTROCHEMICAL METHOD OF PHOSPHATE REMOVAL
The article is devoted to the study of specific electrochemical removal of phosphate ions from biologically treated sewage. It is shown that, using iron as an anode, it is necessary to provide methods for controlling the dissolution of iron in the treated water. In addition, after-treatment of sewage after electrochemical coagulation is necessary. As an after-treatment filtering through marble chips or limestone-shell rock was used. It is proposed to apply "dry filtering" method to increase the dirt capacity of filters.
