Abstract
The demand and market growth of activated carbon (AC) in drinking water treatment have been increasing over the recent years. This is because of the better properties and relatively lower cost of AC compared to inorganic adsorbents like ceramics. However, there have been limited studies on the effects of AC preparation including type of cleansing agent on the adsorption of metal and the turbidity of treated tap water. Therefore, this research investigated the effect of types of cleansing agent and sorbent dosage on turbidity reduction and metal removal in drinking water treatment. The analysis showed that 200 g dosage of AC that has been cleansed with FeCl3 has the turbidity and metal removal improved the most. For aesthetic value of drinking water though, filtration by using AC cleansed with KOH gave better taste and increasing the sorbent dosage up to 300 g increased this performance.
