Our process is uniquely efficient because it makes phosphorus fully recoverable. First, the phosphorus in sludge is solubilized so that it can be recovered. Then the sludge is centrifuged for solid-liquid separation. The liquid portion, which contains the soluble phosphorus, is reacted with calcium to create brushite crystals.
This innovative technology can recover 62% of the total phosphorus in a sewage facility, which is 150% more phosphorus than other technologies on the market achieve. A pre-commercial pilot was constructed in 2015 and is undergoing optimization.
