Freeze-thaw conditioning effectively dewaters alum and activated sludges, but it works better on alum sludge than it does on activated sludge. The main difference between alum sludge and activated sludge is that activated sludge has high concentratio

The dilatometric technique is used to measure bound water in aerobically digested sludge. It is found that air liberated from the sludge sample during the freezing of the sludge water affects the quantity of unfrozen water (interpreted as bound water

Freezing and thawing sludge has become an economically feasible technique of sludge conditioning in regions where natural freezing is available. Even though the dramatic effects of freeze/thaw on dewatering have been studied extensively, its effects

The chief characteristic that determines the quantity of energy recoverable from the combustion of mixed waste paper (MWP) is the thermal energy of the material as measured by a bomb calorimeter. Mixed waste paper can be divided into 11 groups, accor

The most common means for disposing of municipal solid waste is burial in a sanitary landfill. However, many landfill owners significantly underestimate the total cost of landfill disposal by considering only land and operating costs, ignoring extern

The pyrolytic and combustive reactions of thermally decomposing pelletized refuse-derived fuel in air and nitrogren atmospheres is studied through the experimental determination of the temperature profile within cellulose cylinders. The internal temp

The objective in this study is the development of an understanding of how feed rate affects air classifier performance. Although bridging and choking are known to occur at very high feed rates, separation can also be adversely affected with lower tha
