Anaerobic technology
Guest Editors Paige Novak, Jeremy Guest and Aijie Wang introduce the Anaerobic technology themed issue of Environmental Science: Water Research & Technology.
Trickling filters following anaerobic sewage treatment: state of the art and perspectives
This paper reviews the experience of the last 20 years of research, design and operation of UASB/TF systems.
Emerging investigators series: revisiting greenhouse gas mitigation from conventional activated sludge and anaerobic-based wastewater treatment systems
Elucidation of N2O formation mechanisms in aerobic-based wastewater treatment is essential for effective greenhouse gas mitigation, whereas mainstream anaerobic treatment requires improved methane recoverability.
Current status and perspectives on anaerobic co-digestion and associated downstream processes
Anaerobic co-digestion (AcoD) has the potential to utilise spare digestion capacity at existing wastewater treatment plants to simultaneously enhance biogas production by digesting organic rich industrial waste and achieve sustainable organic waste management.
Amending anaerobic bioreactors with pyrogenic carbonaceous materials: the influence of material properties on methane generation
The impact of pyrogenic carbonaceous material amendments on methane production in short-term anaerobic batch reactors depended on multiple material properties, including, but not limited to, electrical conductivity.

Achieving high-rate hydrogen recovery from wastewater using customizable alginate polymer gel matrices encapsulating biomass
Alginate encapsulation matrices selectively retained hydrogen producing biomass, achieving reliable high-rate production of hydrogen at various operating conditions.
Exploring the limits of anaerobic biodegradability of urban wastewater by AnMBR technology
Anaerobic membrane bioreactors (AnMBRs) can achieve maximum energy recovery from urban wastewater (UWW) by converting influent COD into methane.
An anaerobic hybrid bioreactor for biologically enhanced primary treatment of domestic wastewater under low temperatures
Anaerobic hybrid reactor system for the generation of methane-rich biogas and energy. An energy-positive alternative to conventional primary treatment of raw domestic wastewater.
Anaerobic membrane gas extraction facilitates thermophilic hydrogen production from Clostridium thermocellum
Clostridium thermocellum is among the most efficient bacteria to convert cellulosic biomass into H2 during dark fermentation.
Investigation of sludge reduction and biogas generation in high-rate anaerobic side-stream reactors for wastewater treatment
Activated sludge systems incorporating a 2 day anaerobic side-stream reactor (ASSR) show significantly decreased waste sludge production.

Removal of antibiotic resistance genes in an anaerobic membrane bioreactor treating primary clarifier effluent at 20 °C
Antibiotic resistance genes are removed by anaerobic membrane bioreactors at 20 °C.
Hydrogen consumption and methanogenic community evolution in anodophilic biofilms in single chamber microbial electrolysis cells under different startup modes
GeoChips based on mcrA and cytochrome genes to evaluate community structure variety of methanogens and electron transfer process.
Efficient biorefinery of waste activated sludge and vinegar residue into volatile fatty acids: effect of feedstock conditioning on performance and microbiology
Biorefinery of waste activated sludge into carboxylic acids, particularly low molecular fatty acids, is of major interest due to its carbonaceous characteristics.
Effect of pyrolysis on the removal of antibiotic resistance genes and class I integrons from municipal wastewater biosolids
Biosolids carry a substantial portion of antibiotic resistance genes (ARGs) leaving wastewater treatment plants. Pyrolysis substantially reduces ARGs in biosolids.
