Methane Generation Using an Anaerobic Biodigester From Waste Leachate Water

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 2, March/April 2026.
ABSTRACT Leachate wastewater (LWW) is characterized by slow biodegradation and low biogas production due to resistant materials and limited biological activity. Therefore, applying pretreatments is essential to improving biodegradation potential, which consequently boosts energy recovery.

Evaluation of ammonium removal from sludge return liquor using a pilot‐scale microbial electrolysis cell

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 3, Page 638-648, March 2026.
Abstract BACKGROUND Microbial electrochemical technologies (METs) enable separation of ammonium from nutrient‐rich waste streams, such as sludge return liquors, using bioanodes that consume organic matter to generate electrical current. Quantification of ammonia recovery performance in pilot scale METs treating real wastes under industrially relevant ...

Understanding the Role of pH Regulation and Neutralizing Agents in Organic Acid Production and Growth of Aspergillus oryzae

Biotechnology and Bioengineering, Volume 123, Issue 1, Page 116-133, January 2026.
We show that pH and neutralization strategy strongly influence the growth, pellet morphology, and organic acid production of Aspergillus oryzae. Acidic and alkaline conditions lead to hairy, dispersed pellets, while near‐neutral environments favour compact pellet formation.

Influence of hydraulic retention time on the psychrophilic hydrolysis/acidogenesis of proteins

Water Science and Technology, 2016
The influence of the hydraulic retention time (HRT) on the anaerobic hydrolysis of complex substrates has been studied under psychrophilic conditions. For this purpose, a continuous stirred tank reactor was operated at 15 °C and neutral pH and gelatin was considered as a model protein. Three HRTs have been tested: 12, 21 and 36 h.

Modeling of Anaerobic Digestion of Complex Substrates [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2003
A structured mathematical model of anaerobic conversion of complex organic materials in non-ideally cyclic-batch reactors for biogas production has been developed. The  model is based on multiple-reaction stoichiometry (enzymatic hydrolysis, acidogenesis,
