Abstract In a mesophilic (30–35° C), sulphidogenic, ethanol-fed expanded-granular-sludge-
blanket reactor, sulphate, at loading rates of up to 10.0–12.0 g Sl− 1␣ day− 1, was removed …

In an ethanol-fed expanded-granular-sludge-blanket (EGSB) reactor at 33° C, 80–90% of
the sulphate load was removed at a rate of 4 g S/ld, provided that at least 6 g chemical …

Thermophilic sulfate and sulfite reduction was studied in lab-scale Expanded Granular
Sludge Bed (EGSB) reactors operated at 65° C and pH 7.5 with methanol as the sole carbon …

The feasibility of sulphate removal from sulphate-rich wastewater using an anaerobic fixed-
bed reactor was investigated. The bioreactor was installed at a chemical industry producing …

Thermophilic sulfite and sulfate reduction offers good prospects as part of an alternative
technology to conventional off-gas desulfurization technologies. Thermophilic sulfate and …

In acetate‐fed, expanded granular‐sludge‐blanket reactors with a liquid upflow velocity
between 3.5 and 4.5 m/h and pH 8.0 to 8.5, calcium‐containing tap water tended to select for …

An expanded granular sludge bed reactor, inoculated with acclimated sulfidogenic granular
sludge, was operated at 33° C and fed with acetic acid as COD source and sulfate as …

The performance of a new sulfide‐oxidizing, expanded‐bed bioreactor is described. To
stimulate the formation of well‐settleable sulfur sludge, which comprises active sulfide …

Several methods were tested to optimise sulphate reduction and minimise methane
formation in thermophilic (65°) expanded granular sludge bed reactors fed with a medium …

The use of an upflow staged sludge bed (USSB) reactor for the optimization of acetate
removal during treatment of sulfate rich wastewaters was investigated. The USSB treated a …
