Nexom
About
Nexom is a wastewater treatment technology company headquartered in Winnipeg, Manitoba, Canada and a member of the Axius Water family of companies alongside Aero-Mod, ATAC Solutions, EDI, EOSi, MITA Water Technologies, and Napier-Reid. Recognized by Global Water Intelligence as the most significant player in North America's lagoon industry, Nexom designs, supports, and supplies technologies for nutrient removal and cleaner water across municipal, industrial, and First Nations applications. Their cold-weather nitrification system SAGR achieves sub-1 mg/L ammonia nitrogen in water temperatures below 1 degree Celsius, and has been redesigned to be 35 to 65 percent smaller than prior generations. Blue PRO reactive filtration delivers ultra-low phosphorus removal down to 0.02 mg/L through continuous sand filtration with chemical precipitation. BioPorts MBBR and IFAS media provide BOD, ammonia, and nitrate removal in constrained footprints for both greenfield and retrofit installations. The Cyclor Turbo activated sludge system offers compact treatment through a partnership with SUEZ. Nexom holds exclusive North American distribution and manufacturing rights for MITA pile cloth disk filters, which achieve Title 22-approved reuse water and phosphorus removal below 0.1 mg/L across over 1,000 installations worldwide. Additional lagoon technologies include optAER aeration upgrades and IDEAL intermittently decanted extended aeration lagoons. Through their SiteWorks division, Nexom provides full-service installation, maintenance, aftermarket parts via Diffuser Express, and design support that delivers final design-ready drawings to engineers.
