Direct Drainage Reviews

The BD BioDisc Sewage Treatment System delivered as a single, packaged system, the Klargester BioDisc range, offers affordable running costs due to its unique design and operational efficiencies.

Available in 600mm invert and 1100mm Invert

*PE Based on Flow - Commercial applications will differ to Residential

Optional Sample Chamber

An air blower system is not needed to power the commercial BioDisc because it is powered by reliable rotating biological disc technology, which drives the wastewater treatment process in a highly efficient way.

The unique design of the Klargester Commercial BioDisc range has a proven track record for high-quality performance, superior reliability and low operational costs.

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.
