ORIGINAL PAPER
Influence of aeration level on dynamic of sewage sludge composting process in bioreactor
Journal of Research and Applications in Agricultural Engineering 2007;52(1):68-72
KEYWORDS
ABSTRACT
The problem of sewage sludge composting becomes the subject of many scientific investigations. The presence of oxygen is the main parameter which influences on composting process. This paper presents the research on the influence of aeration level on the intensity of the process. The 2-chambers bioreactor for modeling of aerobic and anaerobic processes of organic matter decomposition was used It was found that higher level of aeration influences on more intense dynamic of the process which is expressed with temperature increase and rapidity of physical and chemical changes. However ultimately the quality of composts obtained as result of different aeration intensity is similar.
