Enhanced Separation of Incinerator Bottom Ash:

2020-5-29  The different samples analyzed in this study were collected at a full-scale enhanced mechanical separation plant treating bottom ash from a grate-type incinerator burning residual municipal waste. The layout of the advanced separation plant is shown in Fig. 2 . The adopted separation sequence is based on a number of unit operations including size reduction, manual sorting, size classification, as well as magnetic and eddy-current separation.

Wet physical separation of MSWI bottom ash TU

The wet separation system can recover more metals of all size fractions down to 0.3 mm. Wet separation provides an important advantage through the wet screening process, as fine particles and organics are washed out from the granulate fractions, thereby improving the environmental quality of building products.

Recycling of municipal solid waste incinerator fly ash

2013-3-1  The presence of a dense medium (quartz sand in this study) is not only helpful for the removal of the salts, but also for the separation of the fly ash particles. After the dense-medium hydrocyclone separation process, heavy metals including Pb and Zn were concentrated in the fine particles so that the rest of the fly ash contained less heavy metal and became both non-hazardous and recyclable.
