CNP technologies boost plant efficiency, provide revenue stream

AirPrex, a flagship technology from CNP – Technology Water and Biosolids Corporation, is a sludge optimization process that recovers high-phosphate mineral struvite after anaerobic digestion but before dewatering. AirPrex saves significant operating and maintenance costs while creating a revenue stream for municipal treatment plants. 

PONDUS is a thermochemical hydrolysis process. PONDUS injects a small dose of sodium hydroxide (caustic soda) to break down microorganisms’ cell walls in waste-activated sludge, which renders the sludge digestible by anaerobic digesters. A treatment plant using PONDUS can expect a 25 to 30 percent increase in methane production. CNP installed the first U.S. instance of this technology at the Kenosha (Wisconsin) Wastewater Treatment Plant.

CNP – Technology Water and Biosolids Corporation designs and supplies nutrient recovery and biosolids treatment optimization systems. CNP’s key technologies are AirPrex, a phosphorus recovery technology, and PONDUS, a thermochemical hydrolysis process.
