“…The increase in sulphate levels, due to sludge wasting on days 162 and 208, is also predicted. Maree and Strydom (1983) operated a series of packed bed reactors on mixture of mine water and sugar, sulphite pulp mill effluent (lignosulphonate), sewage sludge and sewage sludge with sugar. Simulations of only the last two experiments were performed.…”

“…Against the advantage of a smaller reactor, there is the added cost of a stripping column. Alternatively, as in the scheme proposed by Maree and Strydom (1983), a recirculating side stream can be passed through a photosynthetic reactor where the sulphide is partially oxidized to elemental sulphur. Again the benefits of lower sulphide levels are offset by the cost of an additional reactor.…”

“…One of the major gold mines in South Africa produced AMD with a sulphate concentration of ca.4 g/L, while the pH varied between 2.6 and 4.2 (Hobbs and Cobbing, 2007). The sulphate concentration in a platinum mine effluent was typically found to be 2 g/L at neutral pH of 7.4 (Maree and Strydom, 1983). Several treatment methods have been developed, e.g.…”

“…Moreover, the SRB can convert sulfate into sulfide which could be toxic to MPB and decrease methane production [6]. Methanogenesis inhibition by 50% has been observed when H 2 S, the free soluble form of sulfide, was present in water with a concentration being over 50 mg/L [7,8].…”

h i g h l i g h t sSuccessful application of UASB in treatment of rich organic S-bearing wastewater. Sulfate in effluent was higher than influent at COD/SO 4 2À ratio of 8 and 5.Conversely, sulfate in influent was higher than effluent at COD/SO 4 2À ratio of 1.5.Archaea and bacterial community varied greatly with altered OLR. Some species can be responsible for S release from organic sulfur compounds.a r t i c l e i n f o a b s t r a c tThe feasibility of treating of chemical synthesis-based pharmaceutical wastewater containing rich organic sulfur compounds and sulfate using an upflow anaerobic sludge blanket (UASB) was investigated. The initial COD/SO 4 2À ratio of 8 in the wastewater varied from 5 to 1.5 after adding sulfate. Of interest that under the condition of COD/SO 4 2À at 8 and 5, despite the simultaneous generation of sulfide and hydrogen sulfide, the sulfate concentration in the effluent was higher than in the influent. This is due to the sulfur release in the form of sulfate during the degradation of these organic sulfur compounds in this reactor. Conversely, at COD/SO 4 2À of 1.5, influent sulfate was higher than effluent sulfate due to reduction of more sulfates in the reactor. At COD/SO 4 2À of 8, for practical application, the optimum OLR was found to be 8 kg COD/m 3 /d, where a nearly 70% COD reduction occurred with biogas containing 63% methane. In this stage, the distribution of the archaea and bacterial community varied greatly with altered OLR (accompanied with prolonged operation time). Some species, such as Lysinibacillus sphaericus, Clostridium cellulovorans were expected to be partly responsible for S release from some organic sulfur compounds in the reactor. By increasing the sulfate loading at a COD/SO 4 2À ratio up to 1.5 resulted in a light inhibition of methanogenesis due to the high sulfide concentration (1212 SO 4 2À -S mg/L) with no obvious suppression of sulfidogenesis.
