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 کاملComparison of phosphorus recovery from incineration and gasification sewage sludge ash.
Incineration of sewage sludge is a common practice in many western countries. Gasification is an attractive option because of its high energy efficiency and flexibility in the usage of the produced gas. However, they both unavoidably produce sewage sludge ashes, a material that is rich in phosphorus, but which is commonly landfilled or used in construction materials. With current uncertainty in...
متن کاملMetal Recovery from Sewage Sludge Ash for Clc Oxygen Carriers Production
Metals like Fe, Ca, Mn present in sewage sludge ash have been deposited on high surface -alumina with high mechanical resistance used as bed materials during sewage sludge fluidized bed combustion to produce low-cost CLC oxygen carriers. The produced oxygen carriers have been characterized using ICP-MS, X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and surface area (BET) analysis....
متن کاملRecycling and recovery routes for incinerated sewage sludge ash (ISSA): a review.
The drivers for increasing incineration of sewage sludge and the characteristics of the resulting incinerated sewage sludge ash (ISSA) are reviewed. It is estimated that approximately 1.7 milliontonnes of ISSA are produced annually world-wide and is likely to increase in the future. Although most ISSA is currently landfilled, various options have been investigated that allow recycling and benef...
متن کاملOverview of Bio-Oil from Sewage Sludge by Direct Thermochemical Liquefaction Technology
Sewage sludge is an unavoidable secondary pollution produced in the process of sewage treatment. At present traditional methods of treating sludge (e.g. landfill, incineration or land application) have some disadvantages and shortages. Direct thermochemical liquefaction of sludge is a new treatment method, which has the advantage of both treatment and energy recovery. Research progress and appl...
