“…The optimal condition was observed in a zeolite dose of 100 g/L. These observations were consistent with previous investigations [16]. For other bacterial groups, zeolite also plays a role as an adsorbent media in the batch reactor, causing an increase in NH4-N adsorption capacity that impacts on nitrogen transformation and microbial abundance [28].…”

“…Impurities in the zeolite were removed by washing twice and soaking in deionized water for 24 h at 30 °C. After that, the zeolite was dried for 24 h at 80 °C and used as a support for the immobilization of SRB consortium cultures for both batch and continuous experiments [16].…”

“…Another study reported that Indonesian natural zeolite was good inert material for SRB in a laboratory-scale down-flow fluidized-bed reactor. After 9 days of operation, the pH changed to neutral, and sulfate and manganese reduced to 23% and 15.4%, respectively [16].…”

“…However, recent studies showed that zeolite had good potential if applied to the fixed-bed anaerobic bioreactor system [15]. In addition, zeolite materials can be obtained in very large quantities from some areas of Indonesia [16]. Therefore, the utilization of indigenous bacterial consortium and Indonesian natural zeolite in the FBR system was very effective.…”

This research explored the performance of a fixed-bed anaerobic bioreactor system (FBR) using sulfate-reducing bacteria (SRB) from the sediment of Sikidang Crater in Indonesia. Indonesian natural zeolite was used as an inert medium in this bioreactor system. This bioreactor performance was analyzed based on its sulfate reduction efficiency, Cu removal, pH profile, SRB growth, and the changes in mineral composition of the zeolite surface. Based on a batch experiment, the FBR system was operated at 30 °C with a hydraulic retention time (HRT) of 7 days using a zeolite dose of 100 g/L. After its operation, a large amount of SRB (up to 1.5 × 105 cells/mm2) was entrapped and present in the zeolite. This bacterial consortium could reduce sulfate and copper by around 68% and 99.96%, respectively. In addition, the pH value of the bioreactor changed to neutral, which indicated a good performance of the operation. The result of the Energy-Dispersive X-ray (EDX) confirmed that copper removal was caused by the formation of copper-sulfide precipitation. Mapping also revealed that both copper and sulfur were precipitated at the same location.

“…The higher pH levels, the higher concentration of S 2that would react with a metal ion (Cu 2+ ) to form CuS as shown by the eq. 5 [15,24]: (5) The high concentration of S 2in the SNW was probably not only from sulfide, but a reduction of sulfate due to the existence of bacteria and alkaline condition (the addition of Ca(OH)2) could also form S 2- [24][25][26][27][28][29][30].…”

The overall objectives of the research were (1) to study the capability of sodium hydrosulfide (NaHS) and sulfidic natural water (SNW) of Sebau in recovery of Cu 2+ , (2) to investigate the potency of integrating treatments of neutralization with sulfidization using SNW of Sebau in removing Cu 2+ from acid mine drainage (AMD) collected from Batu Hijau site. The first objective was achieved by separately reacting (in situ) NaHS and SNW with a Cu 2+ solution at pH 5.5. The second objective was answered by conducting treatments of lime-neutralization by the use of three levels of pH (4.0; 5.5; 7.0) and sulfidization using SNW collected from Sebau, Lombok Island at three sampling points. The result showed that NaHS (61.6 mg/L) could precipitate Cu 2+ solution (44.45 mg/L) up to 71.3%, while SNW of Sebau could precipitate Cu 2+ solution (44.45 mg/L) for almost 100% at pH 5.5. The results also revealed that SNW could precipitate the remained Cu 2+ in the AMD from the neutralization treatment (pH 4 = 113.5 mg/L; pH 5.5 = 85.01 mg/L; and pH 7.0 = 2.372 mg/L) to 83.84% (pH = 4.0) and 100% (pH = 5.5 and 7.0). Although both pH 5.5 and 7.0 could completely precipitate Cu 2+ in the AMD, by comparing the experimental result with the stoichiometric analysis, it was predicted that pH 5.5 was an optimum pH level for the reaction between AMD and SNW to recover Cu 2+ in the AMD. Without neutralization treatment, SNW showed potentiality to recover Cu 2+ since the combination treatments of neutralization at pH 4 with SNW collected from three sample points resulted in a high percent recovery of Cu 2+ . ABSTRAKTujuan keseluruhan dari penelitian ini adalah: (1) untuk mempelajari kemampuan dari natrium hidrosulfida (NaHS) dan air belerang alami (SNW) dari Sebau dalam mengendapkan Cu 2+ , (2) untuk menginvestigasi potensi dari pengintegrasian perlakuan pada netralisasi dengan sulfidisasi menggunakan SNW dari Sebau dalam menghilangkan Cu 2+ terlarut yang berasal dari air asam tambang (AMD) dari Batu Hijau. Tujuan pertama telah tercapai dengan mereaksikan secara in situ NaHS dan SNW dengan larutan Cu 2+ secara terpisah pada pH 5,5. Tujuan kedua telah tercapai dengan melakukan perlakuan netralisasi dengan penggunakan tiga level pH (4, 5, 7) dan sulfidisasi menggunakan SNW yang diperoleh dari Sebau pada tiga titik sampel. Hasil menunjukkan bahwa NaHS (61,6 mg/L) dapat mengendapkan Cu 2+ (44,45 mg/L) sampai dengan 71,3%, sementara SNW dari Sebau dapat mengendapkan larutan Cu 2+ (44,45 mg/L) sampai dengan 100% pada pH 5,5. Hasil juga telah menunjukkan bahwa SNW dapat mengendapkan sisa Cu 2+ dalam AMD dari perlakuan netralisasi (pH 4 = 113,5 mg L; pH 5,5 = 85,01 mg /L; dan pH 7,0 = 2,372 mg/L) sampai dengan 83,84% (pH = 4) dan 100% (pH = 5,5 dan 7,0). Meskipun kedua pH 5,5 dan 7,0 dapat secara sempurna mengendapkan Cu 2+ dalam AMD, dengan membandingkan hasil eksperimen dengan analisis stoikiometri, diperkirakan bahwa pH 5,5 merupakan pH optimal untuk reaksi antara AMD dan SNW dalam mengendapkan Cu 2+ di dalam AMD. Tanpa perlakuan netralisasi,...
