摘要

This study presents work done for optimizing the struvite formation in sludge liquors, aiming at the removal of surplus ammonium (NH4). The project consists of lab-scale experiments and the transfer of these results onto a mobile experiment unit. The experiments were conducted through addition of external magnesium (Mg2+) and phosphate (PO4~) compounds to real and synthetic sludge liquor. Variables such as mo-lar ratio of the components, temperature and pH of the reaction mixture, magnesium and phosphate sources etc. were tested. The results led to the design of a pilot plant and pre-liminary findings from this plant are also reported.
