Abstract:
Water is a source of life. Liquid waste goes into the river body can cause a negative
impact on the quality of river water. The advantage of sulfate and sulfide content can be toxic to humans. To reduce sulfate and sulfide content to look for the exact method.
Composite screening can reduce sulfate and sulfide content of the river water. In this
study, composite made from natural rubber as a matrix and active charcoal and cast sand as filler. Filler is used by 5% of the total rubber used. Composites made with filler
comparison between active charcoal with sand cast, namely: 0: 100, 50: 50, and 100: 0.
Composite with comparison of active charcoal : sand cast = 100: 0 has a efficiency
largest in reducing concentrations of sulphate and sulphide to sulphate that is 24,952% and 11,519% for sulfide. In general, the more active charcoal content in the composite the greater the effectiveness of sulfate reduction and sulfide content. The information get from this research are very useful from to solve the problems in the river water and utilization of materials that have not been on used optimal.
