Electrolysis-enhanced anaerobic digestion of wastewater

Bioresource Technology, 2011
This study demonstrates enhanced methane production from wastewater in laboratory-scale anaerobic reactors equipped with electrodes for water electrolysis. The electrodes were installed in the reactor sludge bed and a voltage of 2.8-3.5 V was applied resulting in a continuous supply of oxygen and hydrogen.

Co-digestion strategies to enhance microalgae anaerobic digestion: A review

Renewable and Sustainable Energy Reviews, 2019
Microalgae biorefineries for the production of biofuels and high-value products have captured the attention of academia and industry. Implementing an anaerobic digestion step can enhance resource recovery from microalgae and microalgae residues. Anaerobic co-digestion, the simultaneous digestion of two or more substrates, is an opportunity to overcome ...
