Centrates, originating from sludge management process such as anaerobic digestion, contribute to 1-2% of the wastewater flow but up to 60% and 30% of the phosphorus and total nitrogen load, when these are recycled to the head of the works. To reduce the phosphorus concentration, chemicals such iron-based coagulants are used, but the amounts required are very high and struvite precipitation remains challenging as high concentrations of P of >100 mg/L are needed for this process. Bio-mineral formation of struvite offers a sustainable route for nutrient removal and recovery from wastewater. Funded by the OFWAT Discovery Challenge I, a large demonstration wastewater treatment plant fed with 400-500 L/day was operated to show the feasibility of the bio-mineral phosphorus removal (BMPR) process. In a pilot-scale study, a selected biomineral formation microorganism was added to the reactor as biocatalyst, using Microniche Engineering™ technology and fed with centrate from a full-scale WWTP. Up to >90% phosphate removal was achieved, under open culture conditions, with effluent levels below 3.5 mg P/L. High-purity struvite was recovered from the reactor, confirming effective biomineral formation. These results demonstrate the potential of encapsulated systems for reliable phosphorus removal and struvite recovery, supporting their scalability for advanced wastewater treatment.
