This thesis examined the recovery of nutrients from wastewater through electrochemical struvite precipitation. Two different wastewater samples were collected from the centrifuge dewatering unit of the municipal wastewater treatment plant of Chania: (a) Centrifugate from anaerobically digested primary sludge, and (b) Centrifugate from thickened activated sludge (undigested). Magnesium necessary for struvite precipitation came from a sacrificial magnesium electrode. Several experimental tests were performed to recover the existing phosphorus and ammonia nitrogen contained in the wastewaters. Reacting factors examined were the pH, molar ratio of nutrients and magnesium, as well as the electric current density. Finally, conclusions were drawn, while the results of the present study were also compared to respective literature results.
