In this article, an enhanced recycled filter media for the removal both nitrogen and fluoride compounds from groundwater via filtration process was investigated. Experiments were made to investigate the influence of recycled filter media on removal efficiency of nitrogen and fluride compoundes.. The recycled backwash cake based filter media used at Lithuanian water works were investigated in a pilot test-bench constructed for this research in the Water Management Laboratory of Vilnius Gediminas Technical University.
