The struvite recovery technology, which is owned by CNP-Technology Water and Biosolids and is available in Australia and New Zealand exclusively through the Hydroflux Group, has won an international award which recognises its ability to successfully extract phosphorus-based plant fertilizer from sewage sludge.
The Berlin Water Works (BWB) in Germany won the prestigious Environmental Technology Award “GreenTec Award 2015” – in the Recycling & Resources, Water Supplier category
Since 2010, around 6000 tonnes of fertiliser have been extracted – and sold to farms – thanks to the AirPrex® system which removes the magnesium ammonium phosphate from the sewage treatment plant cycle.
In removing the phosphate, the AirPrex® system not only ensures that pipes and pumps are not blocked with struvite, it also delivers significant savings in both sludge dewatering polymer usage and sludge disposal volumes.
“We are delighted with this award because it recognizes the ability of the AirPrex® system to recover valuable fertilizer and how BWB combined implementation-oriented research and in-house professional’s knowledge and values,” says Chairman of BWB, Jörg Simon.

The AirPrex® process is widely used throughout Europe where it is delivering significant cost savings. For example, several waste disposal companies have seen savings of around 350,000 euros (more than $A500,000) per year.
John Koumoukelis, a Director of the Hydroflux Group, says there are several benefits of using this leading technology in the treatment of wastewater at plants which can service populations ranging from 20,000 up to 1.5 million people.
“While AirPrex® can successfully remove struvite which can then be on-sold as fertilizer, it can also reduce phosphorus load returned to the plant by as much as 90%, reduce polymer consumption, create higher cake solids and reduce a plant’s overall operational expenditure,” he says.
