Anaerobic Codigestion of Municipal Wastewater, Landfill Leachate, and Crude Glycerin: Process Stability and Methane Yield Assessment Using a Screening Design [PDF]

open access: yesWater Environ Res
Anaerobic codigestion of municipal wastewater with landfill leachate and crude glycerin can achieve near‐theoretical methane yields (0.349 L NCH4/g tCODadd). An optimal mixture of 2% leachate and 1% glycerin was identified, as higher glycerin content negatively impacted performance, highlighting the criticality of substrate balance for energy recovery.

Influence of high gas production during thermophilic anaerobic digestion in pilot-scale and lab-scale reactors on survival of the thermotolerant pathogens Clostridium perfringens and Campylobacter jejuni in piggery wastewater [PDF]

open access: yes, 2009
Safe reuse of animal wastes to capture energy and nutrients, through anaerobic digestion processes, is becoming an increasingly desirable solution to environmental pollution.

Controlling granular sludge floatation in uasb reactors

open access: yesWater Science and Technology, 1997
Granule floatation may occur at higher organic loadings, resulting in a loss of active granules and a decrease in the treatment capacity of UASB reactors. Granular sludge sampled from full-scale UASB reactors was studied to investigate the mechanism of granule floatation.

Enhancement of overloaded waste stabilization ponds using different pretreatment technologies: a comparative study from Namibia

open access: yesJournal of Water Reuse and Desalination, 2020
Waste stabilization ponds (WSP) are a well-established wastewater treatment technology in Namibia. However, they are often overloaded and we still lack concepts and technologies for improvement.

Treatment of food processing industrial wastewater using two stages anaerobic system [PDF]

open access: yes, 2014
The wastewater produced by food manufacturing industry is known for its high concentration of COD and suspended solid. In wastewater treatment, anaerobic process is favorable due to its low cost, biogas production, low sludge production and more ...

Anaerobic Treatment of Concentrated Black Water in UASB Reactor at a Short HRT [PDF]

open access: yes
This research describes the feasibility of applying a UASB reactor for the treatment of concentrated black (toilet) water at 25 °C. On average 78% of the influent load of COD at an HRT of 8.7 days was removed. Produced methane can be converted to 56 MJ/p/

Anaerobic treatment of a petrochemical wastewater from a terephthalic acid plant [PDF]

open access: yes, 1992
Anaerobic treatment of terephthalic acid plant wastewater was tested using two UASB reactors (T and U) and a downflow tubular fixed film reactor. UASB T was inoculated with sludge sampled from an anaerobic stabilization pond receiving waste activated ...

Sewage Sludge and Cashew Bagasse Biochars Promote Changes in Selected Physical Attributes Related to the Structure of Degraded Dryland Soil

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
This study evaluated biochars from co‐pyrolysis of sewage sludge and cashew residues on physical quality of a degraded loamy sand soil. SPB applied at 20 Mg ha−1 reduced bulk density by 7.74%, whereas most porosity attributes were driven by soil reconsolidation rather than biochar. Aggregate stability varied with biochar type, with SPB promoting larger
