Frequently Asked Questions

Q: How does the Klargester BioDisc® BC work?
A: Central to the operation of the Klargester BioDisc® BC 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.

• 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.

Q: How easy is the Klargester BioDisc® BC to maintain?
A: The Klargester BioDisc® BC sewage treatment plant is designed for low-cost and easy maintenance.

• Under normal usage your Klargester BioDisc® will require periodic emptying.
• Klargester offers a full post installation inspection and after sales service.
