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 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 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 کاملThe possible use of Sewage Sludge Ash (SSA) in Self-Consolidating Concrete (SCC) for environmental sustainability
Nowadays, waste production is increased due to the growth of technology and excessive use of natural resources as well as production of new chemicals, among which the hazardous wastes are no exception of that stabilization and solidification method is one of the hazardous waste management methods through which the waste materials are stabilized and confined. High flexibility for various polluta...
متن کاملThe Agronomic Value of The Sewage Sludge of Tenerife. Composting
One of the most effective ways of recycling the organic and mineral fractions of sludge from the treatment of domestic wastewater is to compost the sludge with the organic fraction of domestic refuse. In the present study, a compost on a semi-industrial scale was obtained from a mixture of domestic refuse and sewage sludge. The evolution of the different parameters throughout the process was no...
