Moisture Purge System
An airlift type purge system is used in all SSI Aeration fine bubble aeration systems to remove condensate from the piping system. Purging entrained water helps ensure even air distribution to all diffusers in a grid. A ball valve is supplied with the system and is opened manually. Continuous purge systems are available or retrievable-type aeration systems, or where it is not possible to fasten a purge line to a tank wall.
