Innovative, reliable and cost effective, the BioSphere™ MBBR /IFAS System from Evoqua is a fixed-film process using thousands of a patented designed biomass carriers to create a large protected surface area for biofilm growth. As a leader in fixed-film wastewater processes for more than 100 years, Evoqua has designed this system to allow for capacity increases of 200% or more and compliance with ever-tightening permit limits - all within an existing plant footprint.
The BioSphere™ Biological System can be installed either as an integrated fixed-film activated sludge (IFAS) system or as a fixed-film system without activated sludge circulation (MBBR). It utilizes a spiral role aeration pattern generated by medium bubble diffusers to provide complete bioreactor mixing coupled with enhanced oxygen transfer capabilities. In fixed-film mode, the BioSphere Biological System uses a single pass configuration with no return activated sludge (RAS). In IFAS mode, RAS is returned to the bioreactor and the suspended biomass is combined with the fixed film biomass attached to the carriers.
The BioSphere Biological System is ideal for plant upgrades, retrofits or expansions. With no additional tankage required, project costs are reduced, duration is shortened and space is conserved. Suitable for both municipal and industrial wastewater treatment plants, the system can successfully achieve BOD5 to < 5.0 mg/L, and enhanced nutrient removal performance, including total nitrogen (TN) < 3 mg/L. The flexibility and efficiency of the system also makes it a cost-effective solution for the construction of new plants.
