anaerobic digestion is the breakdown of biodegradable organic material by microorganisms in the absence of oxygen or in an oxygen-starved environment.this technology is superior to the landfilling and also the aerobic composting. the aim of the present study was to examine whether the effluent volatile fatty acids from the anaerobic acidogenesis of the food waste can be used du to its high valu...

One of the possibilities to achieve energy neutrality wastewater treatment plants (WWTPs) is implementation anaerobic co-digestion strategy. However, a key factor in its successful on technical scale application components with complementary composition sewage sludge (SS). In 7resent study, influence adding various co-substrates balance digestion was evaluated. The following organic wastes were...
