Name
The bio-mineral P removal (BMPR) process for P removal and recovery from centrates
Description

The wastewater utilities mainly use metal-based coagulants to remove P from wastewater, a solution that presents many drawbacks and alternatives need to be found. In the UK alone, industry plans reveal an anticipated expenditure of over £4.5 billion on P removal schemes between 2025 and 2030, with significant expenditure on small treatment systems. Current options to manage nutrients are flawed by high greenhouse emissions, locking phosphorus to sludge ash, or requiring high chemical use, and offer limited resource recovery options. The bio-mineral P removal (BMPR) process, is a breakthrough novel type of biological technology, based on transformational underlying principles and has the potential to change nutrient removal and the wastewater industry. The use of microorganisms with specific pathways that can specifically and effortless capture nutrients from wastewater, an in return producing bio-fertilisers is increasing in TRL, enabled by the application of immobilisation technologies and offer significant advantages over existing options. The BMPR process is being tested at a large pilot-scale through an OFWAT Discovery project, and it has been tests in urine too, the latter aimed at the Moon and Mars human space exploration for applications through a project funded by the European Space Agency. The BMPR process, is coagulant free, intensified, can be switched on/off, with no sludge production, and allows for high effluent quality (<2 mg P/L) and nutrient recovery as struvite that can be applied in small or large sites. The resulting struvite has very high purity (i.e. similar to the pure synthetic chemical) and its final end use and market is being explored. The bio-mineral P removal (BMPR) process is a breakthrough novel type of biological technology, based on transformational underlying principles and has the potential to change P removal and the wastewater industry.
