Reduction of Excess Sludge in Sewage Treatment by Ozone Application

A new process which attains both excess sludge reduction and phosphorus recovery has been developed. In this paper, characteristics of sludge solubilization by ozone were investigated in batch experiments with sludge taken from an A/O reactor supplied with synthetic sewage and several real wastewater treatment plants. Then, performance of the new developed process was investigated in a laborato...

Environmental Effects of Sewage Sludge Carbonization and Other Treatment Alternatives

Carbonization is a newly developed process that converts sewage sludge to biocoal, a type of solid biomass that can partially substitute for coal during power generation. This study presents an assessment of the environmental effects of various sewage sludge treatment processes, including carbonization, direct landfills, co-incineration with municipal solid waste, and mono-incineration in Taiwa...

Sewage Sludge Ash To Phosphate Fertilizer By Thermochemical Treatment

A rotary reactor and a fluidized bed reactor (both laboratory-scale and operated in batch mode) are used for the treatment of granulates containing SSA and CaCl ) and treating this mixture (possible after granulation) in a rotary kiln at 1000±100°C leads to the formation of volatile heavy metal compounds which evaporate and to Pphases with a high bio-availability. Due to economical and ecologic...
