The Study of Improving Acid Mine Water Quality by Manganese Greensand and Activated Carbon Filtration

Bangka Belitung is one of the provinces in Indonesia known as a tin-producing area. Illegal tin mining results excavated holes. The characteristics water ex-mining pits are acidic and contain heavy metals such iron. This journal aims to determine effect filtration improving quality samples best doses Na2CO3 KMnO4 pre-treatment. Also find out which experiment resulted higher Fe removal efficiency whether treated complies with Regulation Minister Health Number 492 2010. study used primary data pH iron content dependent variables. population this research Alang Lake that taken by random sampling method. was carried on lab-scale two independent variables were sampled replicates every 30 minutes. In experiment, optimum 300 mg/L 0.75 mg/L, respectively. has value 7.4-8.1, concentration 0.25 93.56%, turbidity 0.05-0.75 NTU. Thus, it can be said accordance relevant regulations.Keywords: Activated Carbon, Fe, Filtration, Manganese Greensand, Water Quality
