| Abstract: | Adsorption of wastewater onto rice husk based adsorbents from aqueous solutions was studied to enable comparison with alternative commonly available absorbents. Batch experiments were conducted to determine the effect of method of treatment of rice husk on adsorption. Rice husk, which is a relatively abundant and inexpensive material, is currently being investigated as an adsorbent for the removal of various pollutants from wastewaters. Various pollutants, such as dyes, phenols, organic compounds, pesticides, inorganic anions, and heavy metals can be removed very effectively with rice husk as an adsorbent. This thesis presents a brief review on the role of rice husk and rice husk ash in the removal of various pollutants from wastewater. Studies on the adsorption of various pollutants by rice husk materials are reviewed and the adsorption mechanism, influencing factors, favourable conditions, etc., discussed in this article. It is evident from the review that rice husk and its ash can be potentially utilized for the removal of various pollutants from water and wastewaters. The purpose of this study was to identify the effectiveness of activated carbon for the reduction of pollutants from municipal wastewater. Wastewater samples were collected from drainage systems near leather complex, Kolkata, West Bengal. Analysis showed that the activated carbons used were significantly different in their efficacy for wastewater treatment. It was observed that by increasing the concentration of activated adsorbent, the removal efficiency of both activated adsorbents increased The rice husk based activated carbon was found more efficient 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. Acid treated rice husk is promising, economical and effective adsorbent for arsenic removal from waste water. Rice husk contain cellulose in high amount which has potential to adsorb heavy metal. Acidic modification of rice husk increase capability to adsorb arsenic from solution. The efficiency of acid treated rice husk varies on many parameters like amount of acid treated biochar, equilibrium contact time, concentration of arsenic in waste water, temperature of waste water, and level of pH. The maximum adsorption capacity (qm) was found to be 3.32 mg/g, 3.25 mg/g, 2.26 mg/g at 30°C, 40°C and 50°C respectively for acid treated biochar. |
