The Klargester BA-X BioDisc delivers a reliable, effective and ecologically safe solution for anyone with off-mains sewage disposal needs with the lowest running and maintenance costs of any packaged treatment plant in its class.

The drive motor within the BioDisc runs virtually silently and has a much lower power consumption and a significantly greater life expectancy than a typical aeration unit. Low running costs, combined with the quality and durability of the equipment, all add up to a significantly lower lifetime cost. The BioDisc now also comes with a Loss of Rotation alarm (and Pump alarm on the IPS system) as standard.


  • Certified to European Standard EN 12566 - Part 3 - Annexe B - Performance Tests
  • 7 year extended warranty (terms apply)
  • No noise
  • No smell
  • Lowest maintenance costs
  • Lowest energy usage at 1.3 kw/d - approx 10-14 pence per day
  • Very good access for maintenance
  • No technical or mechanical faults
  • Lowest sludge accumulation and sizeable storage capacity
