a high performance biological process - Biofor®

a high performance biological process - Biofor®
2 Operations in one structure: filtration & intensive biological treatment.

The Biofor® allows an advanced treatment of suspended solids (SS) and carbon and /or nitrogen pollution with no odor. The effluent to be treated is continuously fed into a biological reactor called a « biofilter », passing through materials that retain the suspended solids.

Carbon and/or nitrogen pollution is eliminate due to the development of natural bacteria into a fixed biofilm (purifying biomass) on a mineral support that is also natural, the BIOLITE®.
