| Abstract | ||||
| Surface water and ground water are the basic resources of drinking water insuburban area. Three kinds of waters and were monitored to differentiate its suitability for drinking waters through different technologies used to treat. For three waters characterized results, biological indicators were moderate loads. While, chemical analyses were recorded different water quality indices (WQI). All of the collected samples showed significant improvements in total solids. The only sample that showed slight increases in total solids was the raw water from the surface compared to the other two groundwater resources. In case of system operating with only chlorination for groundwater, increased dosing loads resulted in a bad taste that required GAC filtration units after. In a GAC/RO system operating in water conditions (<500 TDS), reducing the treatment efficiency loading rate to 45% from 60-80% was important for achieving effluent quality more than 150mg/L during events of low TDS content. The performance of both sedimentation/filtration systems was highly dependent on the biological maturity of the system and surface water quality. | ||||
