Koncentrationsstrategier för fosforåtervinning (Swedish)
Abstract [sv]

Avhandlingen fokuserar på koncentrationsstrategier för fosforåtervinning i Östersjöns sediment, en kritisk råvara för gödningsmedel och batterier. Forskningen syftar till att förbättra återvinningsprocessen genom att använda lösningskoncentrationer, förångning och fryskoncentration, för att förbättra fosforåtervinningen. Studien genomfördes genom termodynamiska simuleringar och experimentell validering, och utvärderade effekterna av parametrar som pH, molförhållande, typ av reagens, temperatur och främmande joner på fosforavlägsnande effektivitet.

Abstract [en]

The thesis focuses on concentration strategies for phosphorus recovery in Baltic Sea sediment, a critical raw material for fertilizers and batteries. The research aims to improve the recovery process by using solution concentrations, evaporation and freeze concentration, to enhance phosphorus recovery. The study was conducted through thermodynamic simulations and experimental validation, evaluating the effects of parameters like pH, molar ratio, type of reagents, temperature, and foreign ions on phosphorus removal efficiency.
