Water quality, nowadays, has become a burning issue, as best quality water is needed for daily lives. Numbers of techniques were developed to overcome the environmental issue and currently we didn't have adopted any wastewater treatment to overcome the issue in Quetta city particularly Habib Nala region. Variety of cost effective techniques may be used to treat this water and further may be utilized in agriculture crops, one of them is adsorption. Rice is one of the major crops produced in Pakistan that plays an important role in the rational economy as it is the 11th largest crop production in the country. Kikar trees on the other hand are also abundant in Sindh Pakistan. In this study, Adsorbent used was produced from rice husk and kikar charcoal using H 2 SO 4 as activating agents... The purpose of this study was to identify the effectiveness of activated carbon for the reduction of chemical oxygen demand (COD), total dissolved solid (TDS), total suspended solid (TSS), color, turbidity from municipal wastewater. Wastewater samples were collected from drainage systems near Shehbaz town (Quetta, Pakistan), where main sewage lines of Quetta are combined. The wastewater was treated using two different particle size (180 and 300 µm) and three different concentrations (35, 40 & 50 gram/500 ml) to check the effect of Particle size and concentration on the reduction of impurities present. Analysis showed that the activated carbons used were significantly different in their efficacy for municipal wastewater treatment. It was observed that by increasing the concentration of activated adsorbent, the removal efficiency of both activated adsorbents increased except turbidity that was decreased by increasing the concentration. The maximum percentage removal of COD, TSS, TDS, turbidity, color with rice husk are up to 90%, 80%, 70%, 99.4%, 98% and 67% respectively. While using kikar charcoal reduced the impurities i.e COD 88%,TSS 80%,TDS 65%, Turbidity 98.2%,Color 95% respectively. The rice husk based activated carbon was found more efficient than kikar charcoal based activated carbon for the removal of COD, TDS, turbidity and color while the TDS removal efficiency for both adsorbents was same. After the treatment of municipal wastewater, its quality was found to be appropriate for direct discharge into streams, lakes, rivers. The water could be used for irrigation purpose.
