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...
متن کاملUsing Vitrification for Sewage Sludge Combustion Ash Disposal
The aim of this paper is to show possibilities for effective processing of hazardous waste using the vitrification method, which is recommended for disposing of ash from the combustion of sewage sludge and developing a process for the conversion of waste to a sustainable and environmentally safe product. The use of vitrification solves the problem of utilizing some hazardous waste by simultaneo...
متن کاملEnvironmental Impact of Sewage Sludge Ash Assessed through Leaching
Article history: Received: 22.7.2016. Received in revised form: 2.11.2016. Accepted: 3.11.2016. As part of a wider feasibility study on the possible reuse potential of Croatian sewage sludge ash, ash has been produced by laboratory incineration of sewage sludge from two Croatian wastewater treatment plants. The Croatian sewage sludge ash was tested for soluble heavy metals according to EN 12457...
متن کاملtotalmaterial requirement assessment of phosphorus sources from phosphate ore and urban sinks: sewage sludge andmswincineration fly ash
diversification of phosphorus sources can bring substantial synergy effects within all thesustainable development domains: environmental, economic and social, and such an opportunity should not beoverlooked. urban sinks accumulate phosphorus and other elements and may serve as sources of secondaryraw materials. this paper evaluates phosphorus sources based on their total material requirement (t...
متن کاملRenewable Energy from Sewage Sludge
At present, the main contributors to waste to energy are municipal solid waste, manufacturing waste and landfill gas. Probably we are all most familiar with the first (MSW), which involves the garbage that the garbage men pick up regularly at our homes and which goes to a landfill, a transfer station, or incinerator. Today we are going to introduce you to something relatively new on the alterna...
