Drying sewage sludge by indirect heating by extraction steam from turbine is the best technology for power generation by sludge incineration because the total cost of sludge disposal is the lowest.
Study on application of wastewater treatment addictive made by sludge incineration residue
While its popularization and application is limited by the emission of heavy metals, dioxin, NOx, SOx, etc. Therefore, it is necessary to study the secondly pollution in sludge incineration process.
Environmental impact assessment of sewage sludge incineration treatments
