Abstract:
... Dissimilatory sulfate reduction (DSR) in cake layer of full-scale anaerobic dynamic membrane bioreactor for treating hotel laundry wastewater was studied. Change (Δ) of sulfate concentration (ΔSO₄²⁻) was positively correlated to dynamic cake layer (DCL) development, while ΔS²⁻ was negatively correlated. ΔSO₃²⁻ and ΔSₒᵣgₐₙᵢc ₛᵤₗfᵤᵣ remained around 1.5–2.5 and 1.2–2.3 mg-S/L, respectively. Thus, DSR ...
