Veolia AnoxKaldnes - Moving Bed Biofilm Reactor (MBBR)

The Moving Bed Biofilm Reactor (MBBR) solution by AnoxKaldnes - a subsidiary of Veolia Water Technologies - is a biological process where biofilm grows on carriers suspended in wastewater.

This biological wastewater treatment and biological water treatment process treats pollutants in a cost-efficient way and it is used across almost all municipal and industrial market sectors such as food and beverage, mining, oil and gas, and pulp and paper. AnoxKaldnes provides MBBR based solutions that specifically address the customer, application and market.

MBBR is a stand-alone system which means there is no need for sludge recirculation, leaving only surplus biomass to be removed through downstream separation technology.

Reactors can be used for aerobic, anoxic or anaerobic processes MBBR technology offers the following advantages:

• Compact footprint
• Simple to operate
• Flexibility in choice of downstream separation
• Robust and stable with influent changes
• East to retrofit to existing infrastructure

• To small or remote operation municipalities
• When upgrading or retrofitting medium-sized plants to increase performance
• During tertiary applications where effluent quality is a priority
• In drinking water applications for low concentration removals
• At large plants requiring a minimum footprint
• To industrial applications where: 
  • Production changes challenge conventional treatment.
  • Simple operation and robustness provide added security.
  • Complex compounds require advanced treatment.

A packaged MBBR solution, MBBR Pack, is suited to certain municipal or industrial applications. These cases are often characterised by small flows, seasonal operations and/or remote locations.

MBBR Pack combines the expertise of two Veolia Water Technologies business units: AnoxKaldnes, known for its Moving Bed Biological Reactor (MBBR) systems, and PMT, specialized in standard product manufacturing and containerized solutions. It`s designed within a standard 40-foot high-cube container, offering a compact and efficient solution for small to medium-sized municipal and industrial wastewater projects. It is suitable for wastewater, pre and post-treatment and water reuse. The containerized design ensures easy transportation, quick delivery and installation and it can handle up to 600 kilograms of chemical oxygen demand per day within 25 to 35 square meters.

• Helps ensure a more sustainable and economical approach to production
• Flexibility in choosing downstream separation
• Robust and stable with influent changes
• Easy to retrofit to existing infrastructure
