Aeration System Accessories

Moisture Purge

An airlift type purge system is used in all SSI 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 for retrievable-type aeration systems, or where it is not possible to fasten a purge line to a tank wall.

Pressure Monitoring

Throughout the life of an aeration system, oxygen transfer efficiency may decline somewhat when diffusers become fouled, but headloss can increase dramatically which in turn increases energy costs. A pressure monitoring system enables the operator to better determine the optimal cleaning frequency of membranes. The fouling rate can very by aeration zone, hence it is recommended to install at least one system in each zone.

Acid Dosing System

In-situ Acid Dosing Systems are available to control calcareous deposits in the perforations which will reduce membrane back pressure.
