AnoxKaldnes Moving Bed Biofilm Reactor
The AnoxKaldnes Moving Bed Biofilm Reactor (MBBR) is a wastewater treatment technology composed of an aeration tank are plastic pieces on which biofilm can grow.
The AnoxKaldnes Moving Bed Biofilm Reactor (MBBR) is a wastewater treatment technology that uses biofilm carriers to optimize bacteria cultures for use in industrial and municipal applications. The plastic carriers are mixed with the wastewater by an aeration system, and the treated water flows out of the tank through a sieve. The compact system removes BOD, ammonia, and nitrogen, and the design of systems in flexible based on application.
The AnoxKaldnes MBBR is built and priced to bespoke configurations based on-site requirements.
Goal 6: Clean water and sanitation
This AnoxKaldnes MBBR is applicable to municipal wastewater treatment companies, local governments, pharmaceutical water companies, and chemical/petrochemical companies
The AnoxKaldnes MBBR is built to bespoke configurations and customised to meet the sites specific requirements.
MBBRs are designed with and then purchased though the manufacturer, to ensure that treatment is optimal for specific applications.
More than 600 MBBR systems have been implemented worldwide.

The AnoxKaldnes MBBR system is designed as a tank with an inlet for wastewater and an outlet, covered by a sieve, for the treated wastewater. Small plastic biofilm carriers are mixed in the tank through aeration from the bottom of the tank. These carriers are designed to provide the optimal surface area for biofilm to grow on, effectively treating the wastewater.
This video further explains how the system works.
Technical support is provided by the manufacturer through various water services and maintenance support packages. These packages include water plant maintenance and chemicals for water treatment. In addition all of the packages include remote technical support.
Individual components are available from the manufacturer for replacement through the technical support plans.
The AnoxKaldnes MBBR has has an observed operational lifespan of over 15 years with no reduction in performance.
The manufacturer specifies performance targets related to small plant footprints, accommodating high loading, and creating optimal bacteria culture conditions.
The AnoxKaldnes MBBR was tested by Lund University, to determine the advantages of biofilm thickness control for MBBR performance.
The AnoxKaldnes MBBR must be operated safely and correctly to ensure that users are not harmed by either the growing bacteria or the untreated wastewater.
The system can be coupled with settlers, clarifiers, or disk filters which enable downstream separation of sludge from treated water.
