This product is delivered directly from the supplier, lead times vary.

 

The BM BioDisc Sewage Treatment System, part of the trusted Klargester BioDisc range, is supplied as a complete packaged solution, offering reliable wastewater treatment with exceptionally low running costs.

Available with 600mm or 1000mm invert options, the BioDisc uses proven Rotating Biological Contactor (RBC) technology to deliver efficient treatment performance while maintaining low energy consumption and minimal maintenance requirements.

The system's drive motor operates virtually silently and consumes significantly less power than conventional aeration systems. Combined with the durability and quality of the equipment, this results in a substantially lower lifetime ownership cost.

All BioDisc systems are supplied with a Loss of Rotation Alarm as standard, with Pump Alarms included on IPS systems for additional operational security.

Running Costs

The Klargester BioDisc offers some of the lowest running and maintenance costs of any packaged treatment plant in its class.

Unlike many alternative systems, the BioDisc does not require an energy-intensive air blower. Instead, its highly efficient rotating biological disc technology drives the treatment process, reducing power consumption and ongoing operating expenses.

The drive motor is designed for:

  • Low energy usage
  • Quiet operation
  • Long service life
  • Reduced maintenance requirements

These benefits combine to deliver outstanding long-term value and a significantly lower whole-life cost.
