文摘
- •
A mobile pilot-scale plant was developed for in situ phosphate (Pi) recovery.
- •
Amorphous calcium silicate hydrates (A-CSHs) were used for Pi recovery.
- •
A-CSHs could effectively recover Pi from anaerobic sludge digestion liquor.
- •
About 21% of the dry weight of the recovered product was citrate-soluble P2O5.
- •
The recovered product was proved to be useful as a Pi fertilizer in a pot experiment.
