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.

This compact, modular treatment system is United States Coast Guard (USCG) and International Maritime Organization (IMO) certified and meets stringent environmental standards governing the discharge of wastewater into territorial waters. STDN’s patented marine on-site generation technology uses seawater and electricity to produce an effective sodium hypochlorite disinfection solution for marine sewage treatment. The OMNIPURE 6MR has a treatment capacity of 25 persons (black water) and 12 persons. 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.
