Starting in 2005 with “feed-forward” grain counting and counter-current regeneration of packed-resin beds, we reduced chemical usage & wastewater by 50-60%. In 2012 we added product water pH-monitoring to intelligently trigger a cation or anion “feedback” regeneration. From 2022-2025 we developed and refined our Optimized Regeneration Control (ORC) optional system enhancement to precisely monitor chemical feed by evaluating regenerant conductivity, creating additional chemistry savings and recovering up-to 20% of wastewater.
