Retention Tanks
swtwater.com Fiberglass Wrapped & PE Liner
SWT's Fiberglass Wound Retention Vessels with PE Liner    
Retention Tanks are designed to provide extended contact time when adding chemicals into the water stream. They are perfect for chlorine, KmNO4, phosphate, or acid feeds, and more. When used in conjunction with a static mixer, these vessels will make sure that the chemicals are properly blended into the water supply. Retention Tanks are designed for long life in corrosive environments and when working with strong chemical additives or oxidizing agents.
 
FEATURES:
• Seamless inner shell of molded polyethylene for impact and corrosion resistance
• Wound with miles of epoxy covered fiberglass filament for superior strength and light weight
• FDA and/or NSF-approved materials
• Equipped with bottom drain port
• Available in blue
• 5 year warranty
 
OPERATING PARAMETERS:
• 75 psi maximum operating pressure
• 120°F maximum operating temperature

VACUUM PROTECTION & FLEX CONNECTORS
Fiberglass/composite pressure vessels are rated for an internal negative pressure of 5-inches Hg (17 Pa) vacuum below atmospheric. If negative pressure could ever exceed 5-inches Hg (17 Pa), an adequate vacuum breaker must be installed between the pressure vessel inlet and any valves (see illustration right). For enclosed tank applications, the vacuum breaker should be installed at the highest location in the system plumbing.

System connections to the pressure vessel must accomodate vertical expansion between side, top, and bottom openings. Either flexibility in piping or flex connectors, as shown here, are recommended.
