Moving/ Mobile Bed Bio-Reactor - MBBR

The F.L.I. Brightwater MBBR is a variant of submerged aerated filter technology which uses F.L.I. Brightwater BMax^® media to provide a submerged medium for biological effluent treatment. It provides a small footprint solution for carbonaceous, nitrification, C+N or in anoxic mode for de-nitrification treatment with very low capital and operating costs together with a low headloss. 

Benefits of the F.L.I. Brightwater MBBR -
Simplicity of design, installation and operation;
Retrofits available to existing overloaded works or conversion of a carbonaceous only conventional activated sludge plant to full C+N duty;
High effluent quality of down to 20 BOD / 30 SS and 5 mg/l Ammonia;
Increase of capacity to existing works;
Low capital and operating costs.

The F.L.I. Brightwater MBBR system has been developed to include a number of features that make for simple and reliable operation, whilst being low on Opex.

The MBBR can be designed as a small footprint process solution for a new works, or as a retro-fit to an existing activated sludge plant to increase capacity and improve effluent quality. It can also be operated in applications of high ammonia concentration – such as sludge liquor treatment or leachate treatment - with the continuously moving bed format in order to provide the oxygenation required for the higher load.

The F.L.I Brightwater MBBR process uses specially developed F.L.I. Brightwater BMax^® plastic ring media to optimise biomass growth. Its combination of high specific surface area, media size, shape and open structure were targeted particularly for this application.

The F.L.I. Brightwater MBBR tanks are equipped with a rugged coarse bubble aeration system - requiring zero maintenance, a quantity of F.L.I. Brightwater BMax^® media and a media retaining mesh at the outlet. The tanks are configured to achieve an even flow of effluent across the media and act as aerated attached growth bioreactors.
