ePhos – Electrochemical phosphorus recovery

Fraunhofer IGB has developed and patented a novel process to recover ammonium (NH 4 +) and phosphate (PO 4 3–). In this electrochemical process with a magnesium electrode, NH 4 + and PO 4 3– are precipitated as struvite. This new process has the advantage that no chemicals such as MgCl 2 or NaOH need to be added for the precipitation process.

Anaerobic digestion (AD) is commonly used for the stabilization of agrofood wastes and recovery of energy as methane. Since AD removes organic C but not nutrients (N and P), additional processes to remove them are usually applied to meet the stringent effluent criteria. However, in the past years, there was a shift from the removal to the recovery of nutrients as .
