1Effect of calcium oxide (CaO) and sawdust on adhesion and cohesion characteristics of sewage sludge under agitated and non-agitated drying conditions.

Deng WY1, Yuan MH2, Mei J2, Liu YJ2, Su YX2.

Water Res. 2016 Dec 2;110:150-160. doi: 10.1016/j.watres.2016.12.001. [Epub ahead of print]

Stickiness phenomenon is widely observed in sewage sludge drying practices. This paper is aimed at demonstrating and comparing the sticky properties of sewage sludge through non-agitated and agitated drying tests specially designed for sewage sludge. Special attentions were paid to the effects of additives, i.e. CaO, fine sawdust (FSD) and coarse sawdust (CSD), on the adhesive and cohesive characteristics of sewage sludge. Read More
