Abstract
In this paper the Modified Down Flow Hanging Sponge (DHS) reactor will be a good water treatment technology in the near future. It was used for excellent removal of notorious heavy metals, organic pollutants and harmful microbes. The reactor has advantages like low cost, ease of use and satisfaction level. In order to achieve these objectives, treatment scheme has been investigated. It consists of mixing a chelator with wastewater in different concentrations followed by a Down flow hanging sponge (DHS) reactor. The residual values of heavy metals are (Mn)amount decreases from 1 ppm to zero ppm (100%) after 60 min.,(Fe)decreases from 0.997 ppm to zero ppm (100%) after 60 min. (Cd) decreases from 0.901 ppm to zero ppm (100%) after 60 min. (Cu)decreases from 1.1 ppm to zero ppm (100%) after 60 min. (Pb)decreases from 1.004 ppm to zero ppm (100%) after 60 min. (Ni)decreases from 0.922 ppm to 0 ppm (100%) after 60 min. The results show that removals of fecal coliforms were achieved. From the results of DHS effluent, fecal coliforms decreased from 5.2x106 to 200 and the overall removal efficiency of fecal coliforms is (99.99%) at 37Co.
