Recycling 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 کاملProduction and characterization of glazed tiles containing incinerated sewage sludge.
In this article, glaze with different colorants was applied to tile specimens manufactured by incinerated sewage sludge ash (ISSA) and clay. Improvements using different amounts of colorants, and glaze components and concentrations on tile bodies were investigated. Four different proportions of clay (by weight ratio) were replaced by ISSA. Tiles of size 12 cm x 6 cm x 1 cm were made and left in...
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 کاملRelease and Recovery of Phosphates from Sewage Sludge
Some treatment plants in operation have not been designed to fulfill the required standards of phosphorus removal. A possibility to upgrade the efficiency of phosphorus removal could be elimination of the phosphorus returned with sludge processing liquors by releasing and recovering from sewage sludge. The phosphorus recovery can occur from sewage sludge by chemical methods or from supernatant ...
