Severn Trent De Nora Introduces Marine Sewage Treatment Unit

Severn Trent De Nora, LLC (STDN) introduced the OMNIPURE™ 6MR, a versatile marine sewage treatment system designed to meet the economic and space requirements of all small to mid-sized vessels in the marine industry.

The OMNIPURE 6MR unit is available for immediate delivery and will be publicly exhibited for the first time at the Fort Lauderdale International Boat Show, October 31- November 4, 2002.
