Roop C. Jain, P.E.

Chief Executive Officer & President

Roop Jain has more than 35 years of experience designing air pollution control, odor control, and chemical feed products for the water and wastewater treatment industry. He is the founder of RJ Environmental Inc. (now a subsidiary of Evoqua Water Technologies, LLC), founding member and former EVP/COO of Underground Solutions, Inc., (acquired by Aegion Corporation in 2016), and currently serves as CEO & President of IMS.

Mr. Jain holds a M.S. in Chemical Engineering from the University of Cincinnati, OH (1979), a B.S. in Chemical Technology from the University of Bombay, India (1976), and a B.S. in Chemistry from the University of Jodhpur, India (1973). He is a registered professional engineer in Chemical Engineering in California.

​Mr. Jain's career began with Calvert Environmental. In 1984, under a consulting contract with the City of San Diego, he designed an odor control system for a 200 MGD raw sewage pump station. This effort led to the development of a proprietary mist scrubber technology that became the foundation for a new Calvert product offering.

In 1991, Mr. Jain founded RJ Environmental (RJE), which developed and sold Emergency Vapor Scrubber Systems (EVSS) and Odor Control Scrubbers. He served as VP/GM after its acquisition by US Filter Corporation in 1997. RJE subsequently became a part of Siemens Water Technologies and is now a subsidiary of Evoqua Water Technologies, LLC.

Mr. Jain is the inventor of the Calvert Mist Scrubber and is the principal inventor and co-inventor on four U.S. patents in the EVSS and odor control fields:

• RJ-2000® Emergency Chlorine Scrubber (U.S. Pat. No. 5,518,696);
• LO/PRO® Odor Control System (U.S. Pat. Nos. 5,876,662 and 6,174,498)
• Biological Scrubber Odor Control System (U.S. Pat. No. 7,276,366)
