Comparative Study on the Mn2+ Removing Performance of Several Filters

The Mn2+ removing effect from groundwater by four kinds of filters Zeolites, Activated Carbon, Manganese Sand and a new filter ANJ.SiC, were comparatively studied and analyzed respectively. The results show that, the Mn2+ removing effect of ANJ.SiC is significantly better than the other three. It is an ideal filter in Mn2+ removing, which can be reused for a long time. These filters' surface characteristics before and after saturation were compared through their SEM figures, and the Mn2+ removing mechanism were further studied.
