The Kingspan Klargester BioDisc® is the only packaged sewage treatment plant utilising Rotating Biological Contractor technology for small domestic applications. This process offers inherent cost and performance benefits with a low carbon footprint.
BioDisc® is a high performance package treatment plant which, in normal domestic situations, will produce effluent qualities of better than 10mg/l BOD, 15mg/l SS and 3.8mg/l ammonia.
Features and benefits
- Lowest running and maintenance costs of sewage treatment models in its class
- No noise, no odours
- Suitable for homes with up to 18 people.
- Low profile covers for minimal visual impact
- Invert options to match the site
- Control panel issues an immediate alert when a problem occurs
- Single phase standard power supply
- Optional integral pump available
- Certified to European Standard EN12566-3
How the Kingspan Klargester BioDisc® Works
Central to the operation of each Kingspan Klargester BioDisc® is the Rotating Biological Contactor (RBC), which supports a biologically active film or biomass on to which aerobic micro-organisms, naturally found in sewage, become established. Natural breakdown of sewage can then occur as described below.
The Breakdown Process
Wastewater and sewage flows into the primary settlement zone (1) where solids are settled out and retained. This accumulated sludge should be drawn out periodically.
Partially clarified liquor containing fine suspended solids flows upwards into the first stage Biozone (2) for breaking down by micro-organisms on the RBC. Suspended solids return to the primary settlement zone and the liquor is transferred to the second stage Biozone (3) for further treatment.
Any solids remaining are settled out in the final settlement tank (4) . The very high effluent quality is discharged to a watercourse.
The RBC comprises banks of vacuum formed polypropylene media supported by a steel shaft. This is slowly rotated by a low energy consumption electric motor and drive assembly.
Note:The Kingspan Klargester BioDisc® is designed to deal with normal domestic sewage. If the sewage is likely to contain unusual substances, please consult Kignspan Klargester.
