Technology Offering

Airprex - Magprex

What is it?

Airprex is a struvite crystallization technology. The AirPrex system is installed between sludge digestion and dewatering, therefore using digestate as feedstock. The system works by increasing pH levels in the digestate through CO2 stripping along with intensive aeration. Magnesium chloride is dosed to promote crystallization, and solid struvite can either be harvested at the bottom of the reactor or left in the sludge. In the second case, struvite ends up in the dewatered biosolids, therefore enriching the biosolids with its slow release fertilizer properties.
