Biological treatment of sulphate-rich wastewaters employing dissimilatory sulphate reducing bacteria as remedial agents is an attractive technique and has gained importance in the last few years. Industrial effluents enriched with sulphates are generally deficient in electron donors. And thus cannot be treated biologically without supplementation of carbon through an external source. For scalable operations, however, the carbon source must not be expensive. In this context, present study reports the efficiency of biological sulphate reduction using sugarcane bagasse as a cost-effective carbon source. An average 0.00391 ± 0.001 gL -1 day -1 (3.91 mgL -1 day -1) sulphate reduction was observed reaching maximally to 0.00466 ± 0.001 gL -1 day -1 (4.66 mgL -1 day -1) while employing Desulfovibrio fructosovorans-HAQ2 and Desulfovibrio piger-HAQ6 in a 60-day trial of anaerobic incubation using sugarcane bagasse as growth substrate. These findings will be helpful in developing economical bioremediation processes tending to operate for a longer period of time to reduce sulphate contents of contaminated waters.

“…A review by Gibert et al (2002) found that the nature of the organic matter was a prime determinator of the efficacy of the passive treatment system. For example, the availability of carbon from plant matter is dependent upon decomposition, which is extremely limited in acidic and anoxic conditions (Harris and Ragusa, 2001).…”

“…What in-situ treatment relevant experiments have occurred have generally been performed at microcosm (e.g., carboy vessels; (Castro et al, 1999;Frömmichen et al, 2004;Fyson et al, 1998)) or at best macrocosm (e.g., limnocorrals) scales (Martin et al, 2003). It is largely recently that attention has switched to insitu remediation systems at actual field treatment scales (Gibert et al, 2002).…”

Pit lakes (abandoned flooded mine pits) represent a potentially valuable water resource to mining companies, the environment and regional communities across arid inland Australia. However, the water is often of low pH with high dissolved metal concentrations.The addition of organic matter to the pit lakes to enhance microbial sulfate reduction is potentially a cost effective and sustainable remediation strategy for these acid waters. However, the cost and availability of sufficient quantities of suitable organic substrates is typically limiting in these remote regions. Nevertheless, small quantities of sewage and green waste (organic garden waste) are often available in these areas from the regional towns which support the mines. This paper reports on preliminary microcosm laboratory experiments in preparation for the treatment of an acid (pH 2.2) coal mine pit lake in semi-arid tropical, inland north Queensland, Australia with municipal treated sewage and green waste.A laboratory experiment using microcosms (acrylic tubes) containing acid pit lake water and sediment were treated as follows; controls (untreated), sewage, green waste and sewage and green waste. The pH increased to a maximum of 5.5 in 145 days in the green waste and sewage treatment, with notable decreases of iron, aluminium and toxic heavy metals. Our results indicated that the green waste was a key component in alkalinity production and heavy metal removal.

Abstract. Crab-shell chitin has proven to be an efficient multifunctional substrate for the biological treatment of mine impacted waters (MIW). Beyond its capacity as an electron donor source, this material has shown high efficiency in the neutralization of acidic water and in the removal of metals, especially Mn. In this study, the performance of crab-shell chitin as a substrate for abiotic and anoxic MIW treatment was assessed to isolate its chemical and physical treatment mechanisms.Alkalinity generation and metal (Mn, Fe, Al) removal with crab-shell chitin were evaluated and compared to those obtained using limestone in closed-system and kinetic tests. Raw (R-SC20) and deproteinized (DP-SC20) crab-shell chitin were tested and compared to evaluate the effect of chitin-associated proteins. Anoxic, synthetic MIW (SMIW), with individual metal concentrations of 10 mg/L, was used in all tests. Systems for all tests were prepared and operated inside an anaerobic chamber by mixing crab-shell chitin or limestone with SMIW at predetermined ratios.In closed systems, 5 g/L of R-or DP-SC20 completely removed (≥95%) both Mn and Fe from single-metal SMIW. After 72 h, pH increased from 3 to 9.2-10.2, while 83-187 mg CaCO 3 /L of alkalinity was generated. In contrast, 5-125 glimestone/L only raised the pH to 7.8-8.3, leading to lower alkalinity levels (56-63 mg CaCO 3 /L) and poor metal removal efficiencies (≤85%). In kinetic tests with 5 g-DP-SC20/L, removal of ≥95% of the initial metal load was achieved after 0.5, 6, and 48 h for Al, Fe, and Mn, respectively. Geochemical calculations (PHREEQC) indicate that precipitation of Al-hydroxides and rhodochrosite (MnCO 3 ) and/or MnHPO 4 are the probable mechanisms for Al and Mn removal. In the case of iron, geochemical calculations point to hydroxides precipitation; however, visual observations suggest the formation of green rust, a precursor of other more stable phases like goethite or lepidocrocite. The faster changes observed with DP-SC20 compared to limestone could be attributed to its significantly larger surface area. These results are the first to verify and quantify the capacity of crab-shell chitin to treat MIW abiotically.
