Product Description

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.

Design Specifications

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

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.

Replacement Components

Individual components are available from the manufacturer for replacement through the technical support plans.

Lifecycle

The AnoxKaldnes MBBR has has an observed operational lifespan of over 15 years with no reduction in performance.

Manufacturer Specified Performance Parameters

The manufacturer specifies performance targets related to small plant footprints, accommodating high loading, and creating optimal bacteria culture conditions.

Vetted Performance Status

The product has been tested by a range of academic institutions including Lund University, Aarhus UniversityThe University of Auckland, and the University of Ottawa related to design, functionality, and impact of temperature.

Safety

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.

Complementary Technical Systems

The system can be coupled with settlers, clarifiers, or disk filters which enable downstream separation of sludge from treated water.
