A 6-L, completely mixed anaerobic bioreactor with an external ultrafiltration membrane module was operated for 300 days to evaluate the startup and performance of an anaerobic membrane bioreactor (AnMBR) treating swine manure. The reactor had a successful startup at the initial loading rate of 1g volatile solids (VS)/L/day. After a two-fold increase in loading rate followed by a sudden, two-fol...

The negative energy balance of wastewater treatment could be reversed if anaerobic technologies were implemented for organic carbon oxidation and phototrophic technologies were utilized for nutrient recovery. To characterize the potential for energy positive wastewater treatment by anaerobic and phototrophic biotechnologies we performed a comprehensive literature review and analysis, focusing o...

The objective of this study was to evaluate staging and its effects on reactor performance in a compartmentalized bioreactor, designated the anaerobic migrating blanket reactor (AMBR). The AMBR was operated by reversing the flow several times per day, which allowed for substantial biomass migration without biomass accumulation in the final compartment. During reactor startup, the structures of ...

The biotechnological gas desulfurization process under haloalkaline conditions is widely applied for removal of toxic H2S from sour streams. In this biologically oxidized into elemental sulfur. Recently, the has been extended with an anaerobic step (dual-reactor line-up), increasing selectivity sulfur (S8) ~85–97% and decreasing formation (thio)sulfate. It was also found that biological sulfide...

Cattle manure (CM) is mostly used as an inoculum in order to start-up of agricultural biogas plants or a co-substrate the anaerobic digestion lignocellulosic content. Rumen fluid microbiota also considered be effective lignocellulose digestion. It known that microorganisms ruminal waste facilitate hydrolysis structures. However, there are few studies on effect rumen bioreactor performances when...

Emerging pollutants that have the potential to significantly impact environment include antibiotics. Antibiotic resistance, or microorganisms' ability withstand medications intended kill them, can an on a variety of facets daily life. One most vital resources for life, water, contains antibiotic resistance. This review explains where antibiotics and resistance genes come from, how they contamin...

In design of anaerobic bioreactor, rate equation is commonly used. Mathematical model was developed at steady state condition, to project concentration of gaseous substrate and product in biological oxidation of carbon monoxide with water to produce hydrogen and carbon dioxide. The concept of bioconversion was based on transport of CO from gas phase to liquid phase, as the CO consumption was in...

The aim of the work was to study effect electrolysis on process anaerobic digestion in example poultry manure with an inoculum activated sludge from a municipal wastewater treatment plant. set achieved by solving following tasks: microcopiing during under influence treatment; studying dynamics biogas yield and its component composition change pH values redox potential (ORP) experiments combinat...

Simultaneous ammonium–nitrogen (NH₄⁺–N) removal and orthophosphate–phosphorus (PO₄–P) biomineralization was studied in two granular sludge sequencing batch reactors treating urban sidestream centrate through the one-stage partial nitritation–anaerobic ammonium oxidation (anammox) process. By adding an external source of calcium, concomitant conversion rates up to 0.32 g NH₄⁺–N/(L·days) 12 mg PO...
