W&O Distributes Airvac Wastewater System

January 22, 2009

W&O, supplier of marine valves, pipe, fittings, engineered products and valve automation systems, announced that Airvac, Inc has named W&O the exclusive representative of the company’s marine vacuum wastewater system.

Phillip Nafziger, Airvac, Inc. Manager, Environmental Group, said, “The appointment of W&O, with its nationwide network of offices, will provide unequaled service to W&O’s already excellent services.  We are pleased to announce today W&O’s exclusive representative agreement with AIRVAC, INC.”

The vacuum sewer system provides efficient and reliable wastewater collection and treatment in on-board ship applications.  W&O now offers its marine customers Airvac vacuum valves, sump assemblies, vacuum station equipment and Membrane Bio Reactor (MBR) water treatment technology.

“Airvac, Inc. marine vacuum wastewater systems will provide W&O customers with a proven low maintenance, efficient and reliable sewage collection and disposal system for new construction or retrofit applications of all major marine vacuum wastewater systems” said Jack Guidry, President and CEO of W&O.  “Airvac systems offer complete customization of products to fit virtually any of our customers needs.”

Additionally, Airvac MBR water treatment technology allows customers to maximize their existing tankage through a low-pressure membrane system that separates solids and removes bulky sludge while meeting and exceeding proposed United States Coast Guard (USCG) rules and regulations for discharge of wastewater.
The vacuum process begins when wastewater collects in the toilet or sump assembly.  As the Airvac valve opens, the collected wastewater is propelled into the vacuum piping where, traveling at 15 to 18 feet per second, the wastewater moves from the toilet or sump to the vacuum collection station.  Vacuum pumps located on the collection station maintain a consistent vacuum level throughout the entire piping system.  When the wastewater in the collection tank reaches a predetermined level, the wastewater is transferred to a holding tank or to an MBR water treatment system thereby making room in the collection tank for additional wastewater and preventing back-up or overflow conditions prior to disposal.
