Nutrient recovery

Want to sustainably profit from waste streams? On this page, you’ll read more about nutrient recovery. And how even low concentrations of dissolved base metals can be economically recovered.

Nutrient recovery

Many industry-leading plant managers and facility managers are preparing for the circular economy. Not only because of stricter laws and guidelines, but also because of resource scarcity. They look for cost-effective, sustainable methods for nutrient recovery.

Paques helps you revitalize your resources and sustainably create revenue streams from waste streams.

“We were persuaded by the low power consumption, the recovery of resources and the limited space required. The performance of the plant shows that we took the right decision”

Richard Haarhuis,
Operational Manager at Waterstromen

Biological nutrient recovery with PHOSPAQ®

As phosphate becomes scarce, phosphorus recovery becomes more commercially interesting. PHOSPAQ™ allows facilities to harvest commercial phosphate, by adding magnesium oxide. It is then transformed into struvite, harvested from the bottom of the reactor and separately contained. Struvite is an excellent slow-release, EU-approved fertilizer. Compared to e.g. dosing of iron salts, PHOSPAQ™ is a more cost-effective technology for the recovery of phosphorus.

Profitable nutrient recovery

Although base metals are valuable, recovery via metal hydroxide precipitation is seldom economically attractive. That’s why Paques has developed superior methods for nutrient recovery from low concentrations. Paques THIOTEQ™Metal and SULFATEQ™ technologies offer the alternative for economically attractive metal recovery. These processes produce sulfide from elemental sulfur or sulfate under ambient conditions. Our high-rate systems have proven to be reliable and efficient.
