BIOGAS PRODUCTION FROM WASTE WATERS THROUGH ANAEROBIC CO-FERMENTATION PROCESSES AT LABORATORY SCALE

The present study focuses on suitable materials for co-fermentation used in the biogas production, characterized by increased characteristics in terms of quality and produced quantity in comparison to the situation of not using them. One will present a serial of comparative tests, at laboratory scale, with different material combinations of waste co-fermentation substances, having as basic material residual water from the Timisoara beer factory, 10 % by mass cow whey and 10 % by mass beet molasses. The results indicate the process characteristics and the capitalization potential of the proposed recipes for biogas production. Conclusions are traced with accent on general characteristics for the chosen materials and influence parameters, over the anaerobic fermentation period.
