BiorotorMBBR™ MBBR / IFAS Biological Treatment System
Innovative, reliable and cost effective, the BiorotorMBBR™ MBBR /IFAS System from Wastewater Technologies, LLC is a fixed-film process using the Biorotor™ plates and thousands of 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 20 years, Wastewater Technology designs the BiorotorMBBR™ plants with the potential to increase the media loading to meet changing influent conditions. This design philosophy is very beneficial to new projects where wastestreams are not fully characterized at time of design.
Flexible Answers. Improved Biological Treatment Efficiency.
The Wastewater is led to the BiorotorMBBR™ treatment reactor where biofilm, growing on the plates of the Biorotor™ and within the internal structures of the biomass carriers, degrade the pollutants. Excess biofilm sloughs off the biocarrier in a natural way. The fixed-film biomass is attached to carriers designed to remain in the aeration basin even under hydraulic upset conditions. Aeration and mixing within the BiorotorMBBR™ is accomplished by the use of the Biorotor™ which provides the required energy to keep the biocarriers suspended and completely mixed within the reactor. Treated water flows from reactor through a grid or a sieve, which retains the MBBR biocarriers in the reactor.
Combining the two processes, MBBR and IFAS, allows for the efficient treatment of any wastestream thus achieve the required effluent permits. The flexibility of the BiorotorMBBR™ process allows for treatment to meet typical 20/20 mg/l BOD5/TSS down to enhanced nutrient removal (ENR) limits. Combining the process with Wastewater Technologies BioDRUM™, BioDISC™ or Membrane systems allows for attainment of even stricter discharge limits.
BiorotorMBBR™ Benefits:
- Reduced HP requirement for aeration due to the use of the Biorotor™
- Improved oxygen transfer and reduced operating cost
- Reduced maintenance, elimination of plugging, reduced cost
- Allows for expansion/upgrade without additional tankage; reduced cost
- Nitrogen removal without increased hydraulic retention time
