What International Dioxcide does

International Dioxcide, Inc. is a North Kingstown, Rhode Island-based manufacturer and supplier of chlorine dioxide (ClO2) chemistry and on-site generation systems, operating as a wholly-owned subsidiary of ERCO Worldwide LP. Founded in the 1940s in Rochester, NY by dentists developing an alcohol-free oral rinse, the company has evolved into the largest producer and distributor of sodium chlorite in North America, with two independent production facilities, a dedicated fleet of 55 specially-lined railcars, and multiple distribution terminals across the U.S., Canada, and Mexico. The company claims to have installed more than 1,000 on-site ClO2 generators across North America and serves municipal water utilities, oil and gas operators (covering eight major U.S. basins), industrial facilities, food processors, and wastewater treatment operators.

The company's product portfolio is organized around two interconnected lines. The chemical line consists of ERCOPure™ sodium chlorite solutions (7.5% to 37% concentration), Anthium™ EPA-registered stabilized chlorine dioxide products, Endimal™ non-pesticidal odor-control variants, and the proprietary PurDOX™ 40% sodium chlorate / 8% hydrogen peroxide blended precursor. The equipment line includes the ADOX™ family of on-site ClO2 generators (MG, MGII, MGIII, InLine, Microflow, MiniAC, MiniACT, MiniTEE) ranging from 0.5 to 10,000 lbs/day of capacity, plus the PurDOX™ VB generator. All generators use a vacuum-based eductor design that stops chemical feed automatically if motive water is lost, and PurDOX™ is marketed as a drop-in replacement achieving 90-95% reaction efficiency and documented 17% chemical cost reductions for municipal customers.

International Dioxcide generates revenue through direct sale of generator equipment, ongoing sale of consumable precursor chemicals (pails through railcar volumes), and recurring technical/regulatory services including demand studies, site audits, pilot trials, and preventative maintenance. The go-to-market combines direct enterprise field sales with a network of leading water treatment service providers and engineering firms that recommend and deploy ClO2 systems, particularly in oil and gas basins. Pricing is custom-quoted based on capacity, chemistry, and site configuration, and the company is committed to Responsible Care® through American Chemistry Council membership.
