Laboratory studies were performed for selection of effective adsorbent from various adsorbents based on two methods of adsorption i.e. column method and batch method. Column method was found to be better adsorption technique than batch method to achieve desalination as its Na+ adsorption capacity was more and rice husk ash (RHA) was proved to be the best adsorbent. Rice husk ash has higher percentage of sodium chloride adsorption of 27.83%, followed by rice straw biochar (25.52%), activated charcoal (22.21%) and coco peat (15.46%). Rice husk ash reduced sodium adsorption ratio is from 18.75 to 8.84 below permissible limit (18). Optimum contact time for all adsorbents was found out to be 15 minutes.
