Fly Ash P-Recovery Technology

With Prayon, fly ashes from the incineration of sewage sludge get a new life. They are recycled into phosphate products and side streams can be converted into de-icing products (Ca/Mg Cl solutions) or reused in wastewater treatment plants (Al/Fe Cl solutions).

Performed at a reasonable temperature without a solvent, 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 and semi-industrial operation facilities in Belgium and in Bulgaria.
