Li, Ji (author), Hao, Xiaodi (author), Shen, Zhan (author), Wu, Yuanyuan (author), van Loosdrecht, Mark C.M. (author)A high moisture content of waste activated sludge (WAS) associated with a low calorific value needs to be deeply dried towards self-supporting incineration. On the other hand, thermal energy with low temperature exchanged from treated effluent has great potential for drying sludge. Unfortunately, low-temperature drying of sludge seems to be...journal article 2023

Wang, Xiangyang (author), Shi, Chen (author), Hao, Xiaodi (author), van Loosdrecht, Mark C.M. (author), Wu, Yuanyuan (author)Wet-chemical approach is widely applied for phosphate recovery from incinerated ash of waste activated sludge (WAS), along with metals removed/recovered. The high contents of both aluminum (Al) and iron (Fe) in WAS-incinerated ash should be suitable for producing coagulants with some waste anions like Cl<sup>−</sup> and SO<sub>4</sub><sup>2−<...journal article 2023
