Static Granular Bed Reactor

Traditionally, the main hurdle in using anaerobic digesting systems is the long retention time (18 to 21 days) for conversion of waste streams to biogas. Consequently, large reactor volumes are required to achieve significant conversion of organics to biogas.

The new SGBR process has significantly reduced the biogas production retention time to 24 hours, which reduces reactor waste storage volume. This new process has tremendous potential to treat many of the organic waste streams generated today – such as manure from cattle and hog operations, waste water from food production and processing industries, and waste streams from ethanol and bio-diesel production facilities.

Envirotech Systems, Inc has licensed the Static Granular Bed Reactor (SGBR) from the Iowa State University Research Foundation. The newly developed biomethane production reactor configuration has the potential to revolutionize the way many organic waste streams are handled, making the conversion of energy simple and affordable.
