A Leading Bulk Supplier of Membrane-Grade Potassium Hydroxide (KOH)

Serving industrial- and agricultural-grade needs of caustic potash in the U.S.

ERCO Worldwide, through its affiliates and subsidiaries, is the third largest producer of a potassium hydroxide (KOH), commonly known as caustic potash for both agricultural and industrial requirements across North America. Our KOH production process is ISO certified and, as a Responsible Care® company, our products meet stringent health, safety, and security standards set forth by the American Chemistry Council and the Chemistry Industry Association of Canada.

We Manufacture for Safety and Quality

We manufacture potassium hydroxide at our state-of-the-art facility in Port Edwards, Wisconsin (U.S.), which is the third largest facility in North America. Our KOH product is available in both 45% and 50% concentrations suited for a variety of applications, such as agricultural fertilizers, runway de-icing fluid, alkaline batteries, oil and gas, soaps and detergents, and water treatment. Our Port Edwards facility manufactures KOH through an electrolysis process that uses membrane cell technology – the most environmentally-friendly cell technology currently available.

Additionally, ERCO’s low sodium grade potassium hydroxide has >7 times lower sodium content versus commercial grade KOH typically found in the industry.  This low sodium grade of KOH is ideal for electronics, food and pharmaceutical applications where a low sodium content (chemical formula “Na”) is critical in the formulation.
