Klargester BioDisc Domestic Sewage Treatment Plant

For domestic dwellings without access to mains drainage, the Klargester BioDisc® sewage treatment plant provides a reliable, efficient and environmentally safe solution to your sewage disposal needs. Ideal for locations where discharge is to sub-surface irrigation (soakaway), or to a suitable watercourse where approved by the Regulator, and where a septic tank will not meet the required standards.

How the Klargester BioDisc® Works

Central to the operation of each 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

Biodisc treatment 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 Klargester BioDisc® is designed to deal with normal domestic sewage. If the sewage is likely to contain unusual substances, please seek expert advice on 01296 633000.
