Deep dewatering of sewage sludge and simultaneous preparation of derived fuel via carbonaceous skeleton-aided thermal hydrolysis

To simultaneously solve problems of high water content and poor fuel performance hindering sludge incineration, carbonaceous skeleton-aided thermal hydrolysis was firstly developed in this study. Results showed that thermal hydrolysis could break sludge particle and release bound water. Sawdust as a typical carbonaceous skeleton improved permeability of sludge, decreased the specific resistance to filtrate significantly and lowered effective...
