Sugarcane Vinasse and Glycerol as Potential Carbon Sources for Sulfate-Rich Wastewater Treatment: Mitigating the Impacts of Acid Mine Drainage

Elis Watanabe Nogueira, Leandro Augusto Gouvêa de Godoi, P.T. Couto, Rodrigo B. Carneiro et autres

High Resolution Image Download MS PowerPoint Slide This study investigated the anaerobic co-digestion of sugarcane vinasse (SV) and glycerol (GOH) as potential carbon sources for treating a sulfate-rich and acidic wastewater (pH 4.0–5.4). The sulfidogenic bioreactor operation was divided into six phases, …

Sulfidogenesis establishment under increasing metal and nutrient concentrations: An effective approach for biotreating sulfate-rich wastewaters using an innovative structured-bed reactor (AnSTBR)

Mirabelle Perossi Cunha, Lucas Tadeu Fuess, Renata Piacentini Rodriguez, Piet N.L. Lens et autres

The accumulation of metal sulfide precipitates inside anaerobic reactors treating acid mine drainage (AMD) can harm the long-term operation of these systems and hampers metal recovery. In this context, an innovative anaerobic structured-bed reactor (AnSTBR) was applied in the treatment of lab-made …

Tratamento biológico de drenagem ácida de minas (DAM) em reator anaeróbio de manta de lodo (UASB)

Mirabelle Perossi Cunha

A drenagem ácida de minas (DAM) é um grave problema ambiental proveniente das indústrias de mineração, pois possui altas cargas de sulfato, elementos tóxicos e metais pesados, que podem provocar doenças nos seres humanos ou causar a morte de vidas aquáticas. Sua …

Biological treatment of acid mine drainage (AMD) in upflow anaerobic sludge blanket (UASB)

Mirabelle Perossi Cunha

Acid mine drainage (AMD) is a serious environmental problem from mining industries, because they have high loads sulfate, toxic elements and heavy metals that can cause disease in humans or cause death of aquatic life. Your generation occurs when sulphide minerals, mainly …

BAW temperature sensitivity and coupling in langanite

Mirabelle Perossi Cunha, E.L. Adler, D.C. Malocha

One of the new quartz-like materials belonging to the trigonal 32 class is langanite (LGN, La/sub 3/Ga/sub 5.5/Nb/sub 0.5/O/sub 14/). High-quality langanite single crystals have become available, and although similar in composition and structure to langasite (LGS, La/sub 3/Ga/sub 5/SiO/sub 14/), LGN …
