Extraction of heavy metal ions from municipal effluent after biological treatment

Summary

The results of investigating the extraction of heavy metal ions from the municipal effluent after biological treatment with the use zeolites (clinoptilolite and Glint granulated sorbent) are presented. The zeolite sorption capacity under static and dynamic conditions was investigated. It was shown that only the use of clinoptilolite provided for the elimination of heavy metals to meet the standards for fishery water bodies. A procedure of designing filters with clinoptilolite for the removal of metals from municipal effluent after biological treatment was developed.
