AquaPASS®
Phased Activated Sludge System
The AquaPASS® system is a time-managed activated sludge technology that integrates select unit processes into a single biological treatment system. The system utilizes the Aqua MixAir® system by providing separate mixing with AquaDDM® direct-drive mixers and Aqua-Aerobic diffused aeration. This system has the capability to cyclically operate the aeration and mixing to promote anoxic/aerobic and anaerobic environments with low energy consumption.
