About Carus

The Carus History

Carus Corporation is the world's largest manufacturer of potassium permanganate.  The company was founded in 1915 by Dr. Edward Hegeler Carus, who first performed experiments with the chemical while an undergraduate at the University of Wisconsin.  When World War I in Europe threatened foreign supplies of potassium permanganate to the United States, Edward Carus saw an opportunity and he began production in barns located on the site of what is now Carus Chemical's LaSalle manufacturing facility.

During its more than 85-year history, Carus's ongoing emphasis on research and development, technical support, and customer service, has enabled the company to become the world leader in permanganate, manganese, chemical oxidation, and catalyst technologies.

A strategy of expansion was adopted in the 1990's when Carus acquired Technical Products Corporation (TPC) in 1997 and The Kjell Corporation in 1998.  As a result of these two acquisitions, Carus became the leading U.S. supplier of corrosion control products for drinking water utilities.  In 2000, Carus acquired the permanganate business of Industrial Quimíca del Nalón (IQN) of Oviedo, Spain. This acquisition represents Carus' commitment to develop the potassium permanganate market in Europe, and is an important step to help expand the European market for potassium permanganate.

Carus also provides custom manufacturing services which take advantage of the company's technical, production, and oxidation expertise.  Custom manufacturing at Carus is a "green" oxidation technology which allows for recycling of co-product materials.

Today, Carus Corporation manufactures a wide range of products for municipal, industrial, and environmental markets (i.e. water treatment and air purification) -- with the majority used in environmental applications.  Products include CAIROX® and AQUOX® potassium permanganate, LIQUOX® sodium permanganate, CARULITE® catalysts, and a complete line of corrosion control products including AQUA MAG®, TPC®, and VIRCHEM®
