Biological Water Treatment
Biological water treatment using a Fixed Bed Bioreator FBBR. The biological oxidation of the organics in the water water take place in a submerged and fixed bed biozone comprising a pvc support matrix of 150 - 240 m2/m3 specific volume to provide a stable platform for an attached biomass concentration of up to 9000 mg/l.
The high biomass concentration is largely fixed to the support matrix ensuring the biomass in solution is of low concentration and will not overload the downstream settlement clarifier.
The FBBR process is highly efficient in terms of biological oxidation of organic matter as well as low energy consumption and low sludge production.
The process is extremely biologically stable and can accept long periods of under load, shock loads and periodic overloads.
The FBBR can be used for polishing discharge water with elevated ammonia levels.
Typical treated water standard is a fully nitrified discharge of 15:15 (BOD:Solids mg/l) and better with tertiary treatment.
Typically, the FBBR is ‘containerised’ and standardised plant. Fully packaged including inlet screen and grit removal, biozone, clarification and tertiary treatment using pressure sand filtration. This type of FBBR plant is standardised to populations of 100, 250, 500 and 1000 persons.
This FBBR plant in all of its sizes is available as a plug and play package, manufactured in Ireland and available for delivery globally.

The FBBR plant is a fixed-bed bioreactor using “Attached Growth” technology by means of a submerged, aerated, high surface area media.
The ‘heart’ of the system is a structured matrix of welded and rigid polypropylene media with a very high specific surface area. This allows for high concentrations of attached biomass to be maintained in the Biozone.
The unique flow patterns within the media ensure high rates of biological oxidation with relatively low retention time. The media ensures air bubble retention is prolonged and allows for exceptionally high oxygen transfer rates with low energy consumption.
There are few moving parts within the plant allowing for low maintenance and low operator demands.
The FBBR is well proven over decades, with reliable, robust and trouble free operation.
Due to the gentle but fully mixed environment within the Biozone, the biomass is allowed to grow to a long sludge age before being “sloughed” from the media. This produces excellent effluent with good nitrification, partial de-nitrification and low levels of waste sludge production.
FBBR plants are either pre fabricated steel, package containerised or use insitu concrete tanks for larger plants. Existing treatment plants can be upgraded for capacity and effluent quality by adopting FBBR technology.

actually sludge can be called as solid waste
the sewage water passes through the containers
due to continuous spinning of these containers it gets splitting up
this will be removed through a filtrate
