Use of Granular Activated Carbon for the Treatment of Sea Water

Kavita Kulkarni, Ankur Dhiman and Satendra Kumar

Activated carbon filtration (AC) is effective in reducing certain organic chemicals and chlorine in water. It can also reduce the quantity of lead in water although most lead-reducing systems use another filter medium in addition to carbon. Water is passed through granular or block carbon material to reduce toxic compounds as well as harmless taste and odor-producing chemicals. The study examined the use of granular activated carbon (GAC) pre-treatment for minimization of seawater contents and removal of organic micro pollutants. Batch experiments were carried out for different variables such as time and weight of adsorbent. Reduction in dissolved salts was about 60%.
