=Stimulated by the depletion of phosphate resources and the need to avoid eutrophication, phosphate removal/ recovery has been studied in recent years. The aim of this study is to investigate the feasibility of phosphate recovery from wastewater by the hybrid system consisting of pellet reactor and selectrodialysis. The phosphates will be pre-concentrated in the selectrodialysis and then be recovered by a crystallization process where it will precipitate on to sand grains as calcium phosphate in a pellet reactor |
