ERCO Worldwide is a leading north American manufacturer of sodium chlorite, which is used to disinfect water in a variety of municipal, industrial, and food applications. ERCO Worldwide has two independent sodium chlorite production facilities – one located in Buckingham, Quebec, and the other in Thunder Bay, Ontario, for reliability of supply.

Manufacturing

While sodium chlorate is used to produce large quantities of chlorine dioxide (ClO2) for pulp bleaching, sodium chlorite is the product of choice for producing small quantities of purer ClO2 for water treatment.

Uses

Sodium chlorite is the primary precursor used for the production of ClO2 for smaller-volume applications. ClO2 is the preferred disinfectant in applications where other disinfectants either do not generate the required disinfection efficacy, or where their use produces undesirable effects like bad taste, odour, or the production of chlorinated or oxidized organics.

ClO2 produced from ERCO Worldwide’s sodium chlorite is used across North America in many municipal, industrial, food, beverage, and oil and gas applications as a disinfectant to treat water.

ERCO Worldwide’s sodium chlorite products are registered pesticides in Canada and the United States. ERCO Worldwide produces products that are registered to ANSI/NSF 60 for drinking water additives, American Water Works Association’s (AWWA) sodium chlorite standard, and for use as a Kosher food contact product.
