Abstract
One of the brackish water treatments is adsorption. In this research, two kinds of zeolite were compared as adsorbents. Zeolite A is obtained through physic activation by heating at 600 oC. Modified zeolite using surfactant HDTMA-Br will produce Zeolite B. Both types of zeolite were characterized using SEM, XRD, and PSA. The results of the PSA analysis showed that Zeolite B had a higher surface area, volume, and pore size compared to Zeolite A. The activity of adsorption was measured based on the removal of salinity, turbidity, TDS, and conductivity at various adsorbent mass and adsorption times. The results showed that Zeolite A was able to reduce salinity by 15.38% in 30 minutes and a mass of 6 grams. Zeolite B as much as 4 grams is able to remove 17.31% salinity at the same time. The low ratio of Si/Al values causes the adsorption capacity to be weak. Produced water also does not comply with the requirement standards for clean water and drinking water..
