【 摘 要 】

Sumur Tua Wonocolo has typical groundwater quality i.e. the high total dissolved solid (TDS) and hardness concentration. This groundwater quality was caused by the dissolution of natural composition (napal) of its reservoir. Therefore, groundwater treatment in this area is needed. This study objected to analyze the performance of natural zeolite filter as one single treatment. The research method was fixed-bed filtration column. The performance of zeolite filter was analized by the effectiveness of those filters in reducing TDS and hardness. The natural zeolite was arranged in the columns with independent variable i.e. grain sizes of 0.1 cm, 0.3 cm, and 0.5 cm. Dependent variables in this experiment were zeolite type, filter media thickness (50 cm), and hydrolic loading rate (HLR) 0.33 m/h. The results showed that groundwater treatment by natural zeolite filter with grain size of 0.1 cm was able to reduce TDS and hardness concentration reaching 79,76% and 74,84% of effectiveness respectivelly. The smaller grain size of natural zeolite used, the better performance of that media in adsorbing dissolved ions proven by decreasing concentration of TDS and hardness. However, the higher the effectiveness of the media in reducing TDS concentration, the faster the media will reach the saturation phase.
