application 0f sewage sludge ash to improve engineering properties of clay soil in water structures
different additives have been considered to improve stabilization of the engineering properties of fine-grained soil. the present study investigated the effect of the addition of sewage sludge ash on the compressive strength of clay soil at optimum moisture content and under saturated conditions. the four treatments tested were the addition of 0%, 5%, 10% and 15% sewage sludge ash to clayey soi...
متن کاملSewage sludge to landfill: some pertinent engineering properties.
More stringent controls on the quality of wastewater discharges have given rise to increasing volumes of sewage sludge for disposal, principally to land, using either land-spreading or sludge-to-landfill operations. Current sludge-to-landfill methods generally involve mixing the concentrated sludge with other solid waste in municipal landfills. However, stricter waste disposal legislation and h...
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 کاملSewage 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...
