Anaerobic EGSB System

Expanded Granular Sludge Bed Reactor System for Secondary Wastewater Treatment

The Clean Water Technology (CWT) Expanded Granular Sludge Bed Reactor (EGSB) is a sophisticated modification of the UASB technology, operating at high up-flow velocities while promoting better mass transfer.  The EGSB removes high levels of organic material in a small volume.
