ROTATING BIOLOGICAL CONTACTOR (RBC) or BioDisc® Wastewater Treatment Plants
RBC or BioDisc wastewater treatment plants in France usually have three
treatment stages to the process. One chamber is called PST (primary settlement
tank), the second one called the biozone, and the third stage is called FST
(Final Settlement tank) The PST acts as a pre-treatment tank, the "biozone"
holds the rotating treatment discs and the FST performs a final clarification.
At first the sewage flows into the PST then through the biozone, and finally
through the FST. The discs in the biozone turn slowly allowing aerobic bacteria
to attach to them and grow. The constant rotating movement ensures that the
media or discs go through a constant cycle of air contact and full submerging to
pick up the liquids for digestion and this also allows an accurate transfer
system within the wastewater treatment plant that equalises the outflow rate
from the BioDisc wastewater treatment plant.

wastewater treatment plants in France have the following advantages:
- Low capital costs compared to treatment plants of similar
- Low operating costs from under 50W to 370W power requirement over
the range; substantially less than pump and blower alternatives.
- Low lifetime
costs particularly the drive motor with a longer service life than the pumps and
blowers fitted to air-blown wastewater treatment plants.
- Rotating Biological
Contactor (RBC) technology with inherent cost and performance benefits.

are potentially re-useable.
- Simple mechanical process
ensuring low operating and maintenance costs.
- All units supplied with a linked
Control Panel with single phase supply converted within the panel to 3-phase
prior to connection to the drive motor for larger units.
- Proven 34 year plus

- Consistent treatment
performance and effluent quality.
- Certified to European Standards EN 12566 – 3
with 95% pollution removal under varying loads and conditions.
- Patented Flow
Management Process (KPFM) provides flow and biological balancing smoothing out
biological load variations and flow peaks and troughs.
- Hydraulic separation
using KPFM ensures all wastewater is fully treated without by-passing, a symptom
often associated with wastewater treatment plants that rely on pumps or

addition of chemicals or cultures.
- KPFM allows for 6 hours of retention within
- Capability to adjust the waste water treatment plant performance in
line with future changes to legislation.
- No process maintenance required.
- Sludge return pump option enhances performance and is configurable to help
overcome seasonal variations.
- High effluent qualities

- Installation minimizes visual impact.
- No odour and very minimal
