ABSTRACT: Rain water is an important source to feed the groundwater aquifer,
whether directly or by harvesting and recharging. The importance of
purification is for reducing the risk of pollutants from recharging runoff
rainwater. The use of sand filter as a technique considered not expensive and
commonly used for removing contaminants from water and wastewater treatment
industries. The methodology used laboratory testing, by designing and
constructing pilot plant to experiment the sand filter for purification, and
made simulation for the infiltration of storm water through sand filter of 2
meters depth, in order to find the relationship between the depth on one
hand, and the removal of suspended solids and fecal coliforms bacteria on the
other hand, to know the effective depth that gets the purification. The
research results during three days of infiltration show that the sand filter
can remove fecal coliforms bacteria at a depth of 150 cm, and provide
purified water with a concentration of suspended solids less than 20 mg/liter
at a depth of 75 cm.
