Agrobics applies biomass immobilization as the major technique for improving operational characteristics of anaerobic treatment of high load effluents.

The advantages of the immobilization of biomass are:

Immobilized biomass tolerates higher organic loading rates (higher than 15 gBOD/l/d) and decreases the required volume of bioreactor and retention time. Immobilization of cells with a high concentration of biomass significantly reduces the start-up period of the bioreactor.

Entrapping bacteria protects them from predation, water, and nutrient stress, and it allows for a larger bacterial population over a longer time interval.
