ANAEROBIC DIGESTION PROCESS, IN TWO PHASES, OF SLUDGE FROM THE TREATMENT OF WASTEWATER WITH ORGANIC CONTENT. THE INVENTION IS CHARACTERIZED BY THE SEPARATION OF THE ACIDOGENIC PHASE AND THE METHANOGENIC PHASE, PLACED SUCH PHASES IN SERIES AND IN THE INDICATED ORDER, SETTING THE RETENTION TIME OF ...
The incorrect disposal of the waste generated in the municipalities contributes to water and soil contamination,resulting in a real concern in order to find an adequate disposal as well as obtain by-products that can be used to reduce CO2 emissions.Anaerobic digestion turns out to be the most ...
This paper deals with the effects of pH value, adding ratio and hydraulic retention time (HRT) on WAS acidification during mesophilic phase in two phases anaerobic digestion (TPAD) system through batch experiments. In order to gain the most amount of VFAs for providing more carbon source, the...
The invention relates to a method for anaerobic digestion of municipal solid waste in temperature phases. The invention consists of a method for anaerobic degradation in temperature phases (thermophilic-mesophilic sequential) of OF-MSW (organic fraction of municipal solid waste), by means of which ...
