Editor's Note: Innovation was a big theme at WEFTEC 2014. We'll be featuring a few of the new and better technologies found in the exhibit hall at the Morial Convention Center in New Orleans. Watch each day for the Innovation logo to learn more about new products displayed at the clean-water industry’s flagship exhibition and conference.

 

CNP Technology offered the AirPrex remedy for buildup of struvite (magnesium ammonium phosphate) in wastewater treatment plants. The technology is a sludge optimization and phosphorus recovery system installed between anaerobic digestion and dewatering. Boundary conditions for struvite precipitation are set by air stripping in a reactor and the addition of a magnesium salt.

The company says the technology enables plants to reduce polymer usage by up to 30 percent, reduce phosphorus recycle load by up to 90 percent, and reduce maintenance costs by 50 percent, while generating revenue from production of a high-phosphate granular fertilizer.
