Nov. 27, 2012 - PRLog -- Severn Trent De Nora, a leader in electrochlorination technology, announced that the MARINER OMNIPURE® Series M55 ( marine sewage treatment system has been selected by German ship operator Pronav for use aboard the “LNG Gemini”, a 72,472dwt LNG tanker. The M5508 model, which can treat black and gray water for up to 25 persons, will be installed aboard the vessel in late November 2012 when she is in Subic Bay, Philippines.

Vessels generate sewage that can contain contaminants that have a detrimental effect on water quality and the overall marine environment. The MARINER OMNIPURE system treats sewage from such marine applications and helps lessen the environmental impact of contaminants. The electrolytic process generates a powerful oxidant from seawater to effectively disinfect biological wastes.

The MARINER OMNIPURE system has received the certificate of approval from the United States Coast Guard (USCG) in accordance with IMO Resolution MEPC.159(55). This proved to be a critical factor for Pronav as the “LNG Gemini” makes regular calls to U.S. ports. Certification by the USCG involves testing rigorous environmental standards such as shock and vibration above and beyond IMO requirements. The system also has Bureau Veritas certification to MEPC.159(55) standards.

In addition to MARINER OMNIPURE’s robust and reliable design, Dana Casbeer, marine and offshore product line manager for Severn Trent De Nora, highlighted the system’s compact design and bulkhead-mounted arrangement – a first of its kind. “Engine rooms are getting tighter, and space for sewage treatment systems and other equipment is at a premium. This is where the physical attributes of the MARINER OMNIPURE system unit make it an attractive fit. More than 50 of these systems have been installed over the past three years aboard various vessel types with limited engine room spaces, ranging from multipurpose vessels to PSVs, yachts, fishing vessels and even floating accommodation houses,” said Casbeer.

The contract with Pronav was secured through Barthels + Lüders, a division of Blohm + Voss Repair GmbH, which recently entered into an agreement with Severn Trent De Nora to represent its BALPURE® ballast water treatment system ( and MARINER OMNIPURE Series M55 sewage treatment system in Germany. According to UNCTAD’s 2011 Review of Maritime Transport, Germany is the third largest ship-owning country in the world with 9.17 percent of world fleet tonnage, after Greece (16.17 percent) and Japan (15.76 percent).

“The German market has a lot of potential for ballast water treatment and marine sewage treatment solutions, and we look forward to working closely with Barthels + Lüders to secure more orders for the BALPURE and MARINER OMNIPURE systems. With more than 35 years of electrochlorination experience and a global network of support, Severn Trent De Nora is a proven and trusted partner for prudent ship operators,” said Ulf Hallberg, regional sales manager of Severn Trent De Nora.

Severn Trent De Nora will be exhibiting (stand 2036) at the International WorkBoat Show ( to be held in New Orleans, U.S.A., from 5 – 7 December 2012. Casbeer will be at the event to promote the capabilities of the MARINER OMNIPURE Series M55 sewage treatment system.
