Feasibility of sludge deep-dewatering with sawdust conditioning for incineration disposal without energy input.
TLDR
In this article, the feasibility of sludge deep-dewatering with sawdust conditioning was investigated for incineration disposal without energy input, and the results showed that the moisture content of a sludge cake can be greatly reduced by sawdust conditioner, which could decrease sludge compressibility, reduce bound water content, improve the porosity, and reduce sludge particle size.About:
