Title
Production of elemental sulfur from sulfide and nitrate-laden wastewaters by methanogenic culture via sulfide denitrifying removal process
Abstract

The denitrifying sulfide removal (DSR) process is a biorefinery process that can produce colloidal S0 from sulfide and nitrate-laden wastewaters. At long reaction time the formed S0 produced is reduced back to sulfide by sulfate-reducing bacteria so the resulting in poor conversion rate of S0 is poor. The presence of optimal hydraulic retention time (HRT) for maximizing S0 conversion from DSR wastewaters was proposed by batch assays and then confirmed in continuous flow tests.

► Denitrifying sulfide removal is a biorefinery process to produce elemental sulfur. ► Colloidal S0 from sulfide and nitrate-laden wastewaters was produced. ► Optimal hydraulic retention time for maximizing S0 conversion from wastewaters exists.
