In 1987, Procorp Inc. was founded as a family business in Elkhorn, Wisconsin, to help industrial clients solve their wastewater treatment needs. Not too long after its inception, the organization moved to Milwaukee and became a nationally recognized expert for treatment of high-strength biological waste streams, typically experienced in dairy and food processing operations.

Over the years, Procorp Inc. has introduced numerous innovative concepts for aerobic and anaerobic biological wastewater treatment, as well as physical/chemical processes such as dissolved air flotation and phosphorus removal via a fluidized bed reactor.

In February of 2007, Procorp Inc. and its subsidiary, Sustainable Environmental Solutions LLC, were acquired by privately owned, Ohio-based Thieman Enterprises LLC, and restructured into Procorp Enterprises LLC. The subsequent energy and resources brought to the organization has transformed the company into a technology-driven innovator.

Fresh water has become a critical issue across the United States. To meet these demands, Procorp has invested in expertise used around the world. We have further invested, through R&D efforts, to advance proven technology to meet tougher demands in the areas of phosphorus removal, chlorides discharge and radium removal.

Procorp’s long-term application experience coupled with an infusion of research and technology, and the strong commitment to the environment, has created the ideal platform for a growing portfolio of green technologies for water and wastewater treatment.
