The ClearFox® Fixed Bed Reactor (FBR) is a robust and effective treatment technology using a modification of the well-known biofilm process. The reactor can retain a large amount of biomass quantity that attached on submerged fixed media. Due to the dens biomass on the fixed bed media, the footprint of our fixed bed biological treatment units is much smaller than conventional systems. By utilizing special cascades and aeration sequences, the Fixed Bed Reactor can biologically treat municipal and industrial wastewaters. The ClearFox® Fixed Bed Reactor (FBR) technology has been independently verified by PIA GmbH – a leading notified test facility for wastewater treatment.
For treating domestic wastewater, The FBR does not require any chemicals for operation, and it is totally automatic in operation. This system can be combined with other process steps such as the dissolved air flotation unit and lamella clarifiers.
The FBR is easily managed solution for complex applications. The biology in the fixed bed reactor regulates itself to a large extent and adjustments are made with simple control measures. This self regulation is only possible with submerged, permanently installed fixed growth media (fixed bed), where the nature and the amount of submerged sludge (dry matter content) is of lesser importance. This saves time, as with this reactor it, is no longer necessary to constantly measure the control parameters such as sludge content (via the dry substance measurement TS) to optimize the operation.
The fixed-bed substrate is made up of UV-stabilised polyethylene which is non-porous, squeeze-resistant and will not biodegrade in the foreseeable future. The fixed bed substrate has no toxic or chemical-physical effect on the biological cleaning process, is produced from net pipe blocks which are connected on the front ends. Due to its net-like structure, the material can be blended thoroughly
It has a specific surface (depending on the type of treatment plant) of 100-200m2/ m3. It has no toxic or recognisable chemical or physical effects on the process of biodegradation. The fixed bed consists of stable individual tubelike elements that are arranged vertically and which are sideways permeable (tube network) and that are welded to one another at the head ends to form rectangular blocks. The meshed structure also allows the material to be intermixed horizontally
Advantages:
Expandable and is adapted to each project (more streets parallel, sludge storage etc.)
Possibility to move this plant partially to another place
Every installation with contact to water is consistent to corrosion
Low costs for projecting and construction management
Produce low sludge
Save time for operator; measurement of sludge is not necessary
