AIRVAC vacuum systems can be used in Correctional Facilities
to convey both black and gray water in either combined or separate flow paths. Vacuum collection uses small diameter piping which may be installed horizontally or vertically allowing for flexibility in design layout for new construction as well as routing around existing objects in retrofit situations.
AIRVAC vacuum systems offer many benefits compared to traditional gravity sewers:
• Reduce Water Consumption
• Monitor and Control Water
• Shorten Construction Duration
• Reduce and Isolate Blockages
• Make Flushed Contraband
• Prevent Toilet Flooding
• Eliminate Cross-talk
• Low Operation and Maintenance Costs
How the AIRVAC indoor vacuum sewer system works:
When the push-button on the Combi unit is pushed, the AIRVAC valve opens and differential air pressure propels the contents of the toilet bowl into the vacuum piping.
Traditional gravity piping carries wastewater from the sinks and showers to an AIRVAC sump assembly. When a predetermined amount of wastewater collects in the sump the AIRVAC valve opens.
Wastewater travels at 15 to
18 fps in the vacuum piping and passes through a sewage grinder to reduce
troublesome solids before entering the collection tank.
Vacuum pumps cycle on and off as needed to maintain a constant level
of vacuum on the entire collection system.
When the collection tank fills
to a predetermined level,
sewage pumps transfer the contents to the treatment plant via a force
Prison applications use both the AIRVAC
as well as the overhead vacuum system piping concept (AIRVAC
