| Huge quantities of date pits are generated as wastes once dates are eaten. The generated pits can be reused to produce activated carbon that can be used for treating polluted water.; The production of activated carbon appears to be one of the most important phases of this study. Different permutation-combinations were investigated to achieve an activated carbon with optimum physical characteristics. This part of the study involved three steps: boiling, soaking and a combined step of carbonization mid activation of pits.; The produced AC was tested against methylene blue (MB). This test has been conducted to check the ability of the produced activated carbon (24-hr and 12-hr acid soaked pits) in order to remove the pollutants. The experiment lasted for 12 days for both the 24-hr and 12-hr acid soaked pits compared to the commercial activated carbon, which lasted for 35 days.; To investigate the pollutant removal efficiencies of the produced activated carbon, an experiment was performed by allowing an unchlorinated secondary effluent to pass through three columns, each filled with different types of activated carbon (i.e. 24-hr acid soaked pits, 12-hr acid soaked pits and commercial activated carbon).
