“…Was observed an improvement in sulfate and COD removal during Step D when the metals were added, even with higher COD and sulfate loading rates. Sahinkaya et al (2014) reported a similar result following the addition of Cu, Ni, and Zn species to a sulfidogenic reactor, and observed an increase in sulfate and COD removal rates.…”

“…For example, an increase in the initial sulfate concentration from 1,330 to 3,600 mg/L resulted in a decrease in the sulfate removal rate (960 to 420 mg L −1 day −1 ) (Mohanty, Das, Mishra, & Chaudhury, 2000). In contrast, other studies have indicated that an increase in the applied sulfate concentration can lead to higher removal rates (Bertolino et al, 2012;Poinapen et al., 2009;Sahinkaya et al, 2014).…”

“…*M = metallic ions. The use of SRB requires supplementation with sources of carbon and energy; typical choices include hydrogen, methanol, ethanol, acetate, lactate, propionate, butyrate, and other known products of anaerobic fermentation (Bertolino, Rodrigues, Guerra-Sá, Aquino, & Leão, 2012;Hu et al, 2015;Sahinkaya et al, 2014). However, SRB can effectively utilize many other organic compounds such as vinasse, cheese whey, the sludge from wastewater treatment, and agricultural residues (Hao et al, 2014;Jimenez-Rodriguez et al, 2010;Poinapen, Ekama, Wentzel, & Ekama, 2009), all of which are inexpensive and readily available (Logan, Reardon, Figueroa, McLain, & Ahmann, 2005).…”

The anaerobic biological treatment of sulfate‐rich effluents, such as acid mine drainage (AMD), is mediated by sulfate‐reducing bacteria (SRB). This process involves the reduction of sulfates in the presence of an electron donor. Complex carbon compounds can be used as electron donors. In the present study, was used an upflow anaerobic sludge blanket (UASB) reactor to co‐treat a low‐pH synthetic AMD and cheese whey wastewater (CWW). Were observed higher sulfate and COD removal rates (1,114 ± 88 and 1,214 ± 128 mg L−1 day−1, respectively) at higher sulfate and applied COD loading rates (1,500 mg L−1 day−1). The overall pH of the effluent remained above 6.4 without any bicarbonate supplementation. Almost 100% of the Fe, Zn, and Cu was removed and the presence of metals improved the process. The use of a single reactor to treat AMD and CWW is promising. Practitioner points Wastewater cheese whey was electron donor for treating acid mine drainage in an UASB reactor. Metals additions in the system indicated an increased removal of COD. About 99% of the metals were removed with the treatment.

“…Upflow anaerobic sludge blanket (UASB) reactor has been often used for the treatment of wastewater from animal farms [6,7]. Under anaerobic conditions, roxarsone is firstly transformed to 4-hydroxy-3-aminophenylarsonic acid (HAPA) through the reduction of nitro group [8][9][10].…”

Roxarsone has been extensively used as an organoarsenic feed additive. Part of supplemented roxarsone was discharged into wastewater. UASB reactor has been widely applied to treat high concentration of organics wastewater. However, there was little report about the arsenic accumulation from organoarsenic biotransformation in an UASB reactor. In this study, the accumulation and volatilization of arsenic in a 260-day cultured UASB reactor spiked with 13.2 mg/L roxarsone were investigated. In the anaerobic granular sludge (AGS), the total arsenic concentrations were 5,276.90 ± 366.12 mg/kg AGS at the bottom of anaerobic sludge bed and 10,661.92 ± 539.63 mg/kg AGS at the top of anaerobic sludge bed. Nearly 50% arsenic in the AGS was extracted under acidic conditions, and the main specie of the extracted arsenic was arsenite (As(III)). In the aqueous phases, roxarsone was rapidly transformed into 4-hydroxy-3-aminophenylarsonic acid (HAPA) and unknown organoarsenic, which was further converted to inorganic arsenic and monomethylarsenate (MMA(V)), in which As(III) was also the main species. Volatile arsenic from the reactor spiked with roxarsone was released at a rate of 134.93 ± 6.61 ng/d. Based on the mass balance analysis of arsenic, 23.40% of the influent arsenic was accumulated in the AGS and 0.002% was released in the form of volatile arsenic. The results from this study indicated that the operation of anaerobic digestion reactor treating organoarsenic-contaminated wastewater and the disposal of the residual AGS should be well managed.

“…The bioreactor was run over a 70-day period where indigenous grasses were used to effectively reduce sulfate and iron concentrations, and increase the pH. It was determined that indigenous grasses are a promising biological treatment approach for AMD demonstrating a maximum of 99% iron removal, 80% sulphate removal, and a final pH of 8.5.The sulfidogenic treatment of As-, Fe-, Zn-, Niand Cu-containing AMD was assessed in an upflow anaerobic sludge blanket (UASB) reactor, operated for approximately 500 days(Sahinkaya et al, 2015). As removal efficiency increased to 98-100% due to either the formation of arsenopyrite (FeAsS) or the adsorption of As on metal sulfide precipitates.…”

This review provides a snapshot of papers published in 2015 relevant to the topic of mine drainage generation and control options. The review is broken into 3 sections: Generation, Prediction and Prevention, and Treatment Options. The first section, mine drainage generation, focuses on the characterization of mine drainage and the environmental impacts. As such, it is broken into three subsections focused on microbiological characterization, physiochemical characterization, and environmental impacts. The second section of the review is divided into two subsections focused on either the prediction or prevention of acid mine drainage. The final section focuses on treatment options for mine drainage and waste sludge. The third section contains subsections on passive treatment, biological treatment, physiochemical treatment, and a new subsection on beneficial uses for mine drainage and treatment wastes.
