If it by concentrating raw wastewater with use of membranes is possible to process the concentrated wastewater directly in a biogas reactor and thereby gain energy from the organic matter in the water, the proposed DOGAS method will open up new paths for wastewater treatment. After several test runs at a pilot plant at Samsø late summer/early autumn 2017, it is clear, that it is possible to make this direct concentration with membrane technologies.
DOGAS - Direct concentration of wastewater for biogas production
Direct concentration of wastewater for anaerobic digestion in biogas reactors is possible and will turn traditional wastewater treatment upside down – when the method is fully developed.
