About the Process
Process Solution to Turn Sewage Sludge, Fly Ashes Into a Valuable Product
Our shareholder Prayon has strong commitment to develop sustainable processes. Always looking for closing the Cycle of the Phosphorus and commitment to process any source of Phosphorous, including fly ash, the product of sewage sludge incineration.
With this technology, fly ashes from the incineration of sewage sludge get a new life. The Prayon Ecophos Loop Process recycles these fly ashes into technical grade phosphoric acid. Moreover, side streams can be converted into de‑icing products (Ca/Mg Cl solutions) or reused in wastewater treatment plant (Al/Fe Cl solutions).
The process is safe, sustainable and can be easily implemented at the incinerator site.
As every ash is different, we can test and validate the best solutions for our customers to recycle the ashes in our R&D pilot.
