| Abstract: | This paper presents the possible alternative removal options for the development of safe drinking water supply in the trace
elements affected areas. Arsenic and chromium are two of the most toxic pollutants, introduced into natural waters from a
variety of sources and causes various adverse effects on living bodies. Performance of three filter bed method was evaluated
in the laboratory. Experiments have been conducted to investigate the sorption of arsenic and chromium on carbon steel and
removal of trace elements from drinking water with a household filtration process. The affinity of the arsenic and chromium
species for Fe/Fe3C (iron/iron carbide) sites is the key factor controlling the removal of the elements. The method is based on the use of powdered
block carbon (PBC), powder carbon steel and ball ceramic in the ion-sorption columns as a cleaning process. The PBC modified
is a satisfactory and practical sorbent for trace elements (arsenite and chromate) dissolved in water. |
