THE IMPACT OF MICRO-ORGANISM ACTIVITY ON THE BIODRYING PROCESS
Author / authors
The examination of the biodrying process was performed in a bioreactor with working volume 240 dm3. In the studies used the digested sludge from sewage treatment plants and the organic fraction of municipal solid waste. During the biodrying process were determined: dry matter, organic dry matter, temperature of material and respiration activity. As a result of the process of drying the waste by 10 days the amount of moisture removed was 51.7%. The highest microbial activity was on day 4 of the process when the temperature has reached the maximum 58°C in the upper layer of the waste at the middle of the bioreactor.
