Abstract
The aerobic sludge digestion process involves the separate aeration of waste sludge for long periods of time. This process has been thoroughly investigated in order to develop loading parameters and design criteria for application to plant scale design. Laboratory studies have also been conducted to study the effect of various parameters, such as temperature of digestion, time of digestion, rate of aeration, loading rate and others, on the reduction of organic matter. The results of these investigations have generally shown that the reduction of organic matter is seldom greater than 40% for domestic sewage sludge. In an attempt to make aerobic sludge digestion more feasible, it is the purpose of this study to determine whether blending of the sludge prior to its aerobic digestion has a significant effect on the reduction of organic matter and the time of digestion. The effect of blending waste sludge is to decrease the floc size and possibly make available more active organisms or cells. This would result in a higher transfer of oxygen and organic matter to the cells, thus speeding up the aerobic stabilization of the organic matter.
