The sewage sludge treatment method comprises a first step of utilizing a freeze drying energy circulating system to continuously freeze sludge in a sludge freezing container, unfreezing the sludge after continuous freezing, and performing freezing and unfreezing repeatedly; a second step of dehydrating ...
Feasibility of alternative sewage sludge treatment methods from a lifecycle assessment (LCA) perspective Abstract Sewage sludge treatment and disposal are critical global issues, with concerns including sludge volume/weight, release of pollutants, and other environmental impacts. This study develops a semi...

Sewage sludge treatment
Gaseous discharge from a pelletizing drier used in the treatment of sewage sludge is partially directed back to a combustion chamber that generates an effluent which is fed to the drier. Volumetric re
