(P) removal in wastewater treatment was investigated with attention to the efficacy, kinetics
and mechanism. At concentrations typical of municipal wastewater, P could be removed by
in situ Fe (II) with removal efficiency higher than achieved on addition of FeSO 4 and close to
that of FeCl 3 under both anoxic and oxic conditions. The generation of alkalinity due to
water electrolysis at the cathode created much higher pH conditions compared to FeSO 4 …
