Production of Soluble Microbial Products (SMP) in Anaerobic Chemostats Under Nutrient Deficiency
Publisher: American Society of Civil Engineers
Abstract: It is known that in well-operated anaerobic systems the majority of the residual chemical oxygen demand (COD) present in the effluent is due to soluble microbial products (SMP) generated during treatment. SMP production ...
Biodegradation of PCE in a Hybrid Membrane Aerated Biofilm Reactor
Publisher: American Society of Civil Engineers
Abstract: A continuous flow flat sheet hybrid membrane aerated biofilm reactor (MABR) was used to treat a synthetic wastewater containing perchloroethylene (PCE);
Activated Carbon Addition to a Submerged Anaerobic Membrane Bioreactor: Effect on Performance, Transmembrane Pressure, and Flux
Publisher: American Society of Civil Engineers
Abstract: This study examined the effect of the addition of activated carbon to three, 3 L submerged anaerobic membrane bioreactors (SAMBRs) in terms of chemical oxygen demand (COD) removal, flux, and transmembrane pressure (TMP). ...
Bioavailability and Toxicity of Metal Nutrients during Anaerobic Digestion
Publisher: American Society of Civil Engineers
Abstract: This paper investigates the effect of chelating agents on the bioavailability of Fe and Cu during anaerobic digestion. The results on metal speciation and methane production in anaerobic serum bottles showed that biomass ...
Metal Bioavailability and Trivalent Chromium Removal in ABR
Publisher: American Society of Civil Engineers
Abstract: Trace metal bioavailability and chromium(III) removal were investigated in an anaerobic baffled reactor (ABR) treating a synthetic waste [COD = 4,000 mg/L,
Treatment and Decolorization of Dyes in an Anaerobic Baffled Reactor
Publisher: American Society of Civil Engineers
Abstract: Synthetic organic colorants, the majority of which are recalcitrant in nature, are used universally in many different manufacturing processes. The dyes are released into the environment in industrial effluents and are ...
Soluble Microbial Products in ABR Treating Low-Strength Wastewater
Publisher: American Society of Civil Engineers
Abstract: The chemical composition, molecular weight (MW) distribution, and biodegradability (both aerobic and anaerobic) of soluble microbial products (SMPs) in an anaerobic baffled reactor (ABR) treating low-strength wastewater ...
