The Moving Bed Biofilm Reactor (AnoxKaldnes™ MBBR) is our own proprietary technology, and the biological engine of Kaldnes™ RAS. The MBBR technology allows the microorganisms to grow on sheltered, surfaces inside moving, plastic carriers creating a continuous biofilm process without any risk for clogging and without any need for back flushing. Advantages like low head loss and high volumetric capacity make the process compact and well suited for treatment of large water flows. The process is very robust and easily operated with a minimum need for maintenance.
Hydrotech drum filters
Biomass from the AnoxKaldnes™ MBBR process, fish faeces and excess feed is efficiently separated with Hydrotech drum filters, another well-known Veolia Water Technologies' technology in the industry. The Hydrotech filters have a high hydraulic capacity, are easy to operate and provide predictable results. Typical mesh sizes are 40-90 micron, but can be delivered with mesh sizes down to 10 micron.
