Environmental Impact Benefits:
The bacteria population of the fixed growth bacteria used by the process
is many times greater per unit volume than the suspended growth bacteria
found in conventional digesters. The details of efficiency improvements
are proprietary but could be discussed on confidential basis.
Wastes that can be treated include dairy waste, swine waste, ocean kelp, seaweed and agriculture wastes such as rice hull, grain debris, and silage, municipal and industrial wastewater. Additionally, type 0 and 1 solid wastes (sawdust, cardboard, paper and cartons) are processed when fed in slurry form. Existing treatment plants with conventional anaerobic digesters can be upgraded to enhanced energy production facilities with positive return on investment.
