Klargester BioDisc BA Sewage Treatment Plant for up to 6 Persons*
The Klargester BioDIsc BA is used for Domestic dwellings without access to mains drainage, the Klargester BioDisc provides a reliable, efficient and environmentally safe solution to your sewage disposal needs. It is ideal for locations where discharge is to sub-surface irrigation, or to a suitable watercourse where approved by the regulator, and where a septic tank will not meet the required standard. For added peace of mind, we offer an extended warranty period of 7 years* exclusively for the BioDisc BA, BAx and BB models. *(Terms and conditions apply - to view, click here).
The BioDisc is a packaged Sewage Treatment Plant which utilises the Rotating Biological Contactor technology for small domestic applications. This process offers inherent cost and performance benefits with a low carbon footprint. Where the Klargester Gravity BioDisc demonstrated an efficiency rating equivalent to a performance of 10 mg/l BOD5, 15 mg/l SS and 3.8 mg/l Ammonia.
Choose from either Gravity or Integral Pumped System (IPS): Gravity is the standard option, however where the inlet to the watercourse or soak away is higher than the outlet of the treatment plant you will require the optional Integral Pumped System (IPS) as this will pump the waste water uphill and into your discharge point. The pumped system (IPS) also comes with a high level alarm.
