  dNOx™ Processor For Wastewater Control

dNOx™ is our patented wastewater treatment plant process control technology. It is applicable in oxidation ditch treatment plants as well as sequencing batch reactor activated sludge treatment processes. This technology enables improvements in settling of the activated sludge by providing selective pressure against the growth of filamentous bacteria, improved total nitrogen removal, and energy savings. Our dNOx™ control system is currently installed in several full-scale wastewater treatment facilities. References can be provided on request.
