Moving Bed Biofilm Reactor (MBBR)
MBBR Systems, Tanks & Engineering for Advanced Biological Wastewater Treatment
Engineering, modular systems, rental units and complete MBBR solutions for municipal and industrial applications.
The Technology
What is a Moving Bed Biofilm Reactor?
An MBBR treats wastewater with a biofilm that grows on thousands of small plastic carriers kept in suspension inside an aerated tank. The carriers move freely with the water and air, giving a large protected surface for micro-organisms to break down pollutants — without the sludge recirculation of conventional activated sludge. The result is a compact, robust process that tolerates load variation and is straightforward to retrofit into existing tanks.

- 01Biofilm carriers held in suspension behind retention screens.
- 02Aeration transfers oxygen and keeps the carriers moving.
- 03No sludge return loop — compact footprint, resilient to shock loads.
- 04Stages can be combined for COD, nitrification and nitrogen removal.
