Abstract:
Objectives
The efficiency of the floating treatment wetlands concept depends on several components in it, such as the selection of plants, planting media, floating media, and the application of floating techniques (Solanki et al. 2017; Headley and Tanner 2006). Therefore this study aims to:
a. Evaluate the effect of organic matter on various pond depths in neutralizing AMD.
b. The right type and amount of organic matter to increase the population of SRB as well as a growing medium for floating plants.
c. Obtaining potential plant species as AMD phytoremediation agents.
d. Analyzing the increase in SRB population from AMD pond sediments.
e. Measuring the effectiveness of processing floating wetlands with SRB enrichment in AMD management
Expected Output
The results of this study are expected to provide new technology in the in-situ remediation of AMD in void. The floating treatment wetland technology with SRB enrichment will be useful to water quality in voids left by mining operation.
Conclusion
Based on the research that has been done, it can be concluded that the addition of organic matter floating on the surface can increase the pH and reduce dissolved heavy metals at a depth of 50 cm, 100 cm, and 150 cm. The best organic material that is appropriate to increase the population of SRB is a mixture of oil palm empty fruit bunches with chicken manure, while the best planting medium is oil palm empty bunches. In the application of floating treatment wetland, the addition of SRB inoculation had an effect on the AMD neutralization process, and the population of sulfate-reducing bacteria increased during four weeks of incubation.
