To reduce the energy consumption and cost of drying sewage sludge (SS) to ensure stability during combustion, pyrolysis co-combustion characteristics semi-dry SS after dehydration flocculant bituminous coal (BC) were studied in this work. The results show that decrease moisture content accelerates release volatile substances, increase heating rate can also enhance water matters. Furthermore, BC...

The high volume and unfavorable properties of high-water-content slurries make their treatment difficult costly. Improving the through prefabricated drains combined with surcharge or vacuum preloading represents an environmental economic means reusing these as subsoil. As conventional methods are inefficient in dealing low-permeability slurries, flocculation is often applied. In this study, inf...
