EGSB Anaerobic Reactor

Expanded Granular Sludge Bed Reactor for Secondary Wastewater Treatment

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

EGSB Advantages Include:

  • Byproduct production of usable methane and fertilizers
  • Reduced or eliminated compliance fees
  • Extremely small footprint
  • Good environmental stewardship
  • Very high organic contaminant removal
  • Too short hydraulic retention time (HRT)
  • Low energy usage
  • Ultra high organic loading rates
