A theoretical study of the potential for metal extraction from the incinerated ashes residing in Swedish landfills.

abstract：:Tightening quality standards for European waters has seen a move towards enhanced wastewater treatment technologies such as granulated organic carbon treatment and ozonation. Although these technologies are likely to be successful in degrading certain micro-organic contaminants, these may also destroy compounds which ...
