High-Rate Anaerobic Digestion of Waste Activated Sludge by Integration of Electro-Fenton Process
(
MDPI AG
, 2020 , Article)
Anaerobic digestion (AD), being the most effective treatment method of waste activated sludge (WAS), allows for safe disposal. The present study deals with the electro-Fenton (EF) pretreatment for enhancing the WAS biogas ...
Production and characterization of B-glucosidase from Aspergillus niger fermentation: Application for organic fraction of municipal solid waste hydrolysis and methane enhancement. Biotechnology Progress
(
American Chemical Society
, 2020 , Article)
The anaerobic digestion of the organic fraction of municipal solid waste (OFMSW) is
currently an attractive treatment process with energy production in the form of bio-
gas. Hydrolysis is the rate-limiting step for the ...
