Harold Garfinkel,Ya Zhu,Yunbo Zhai,Karen Hamann,Shanhong Li,Xiangmin Liu,Bei Wang,Xiaoping Liu,Yuwei Fan,Haoran Shi,Caiting Li,Yun Zhu +11 more
TL;DR: In this article, the authors reviewed the methods for the recovery of different forms of phosphorus (wet chemical, thermochemical and electrodialysis) from solid products obtained from different sludge thermal treatment methods (incinerated sludge ash, pyrolysis of sewage sludge char and hydrochar).
