Sewage Treatment Plants

Biodisc RBC Wastewater Treatment Unit

For domestic dwellings without access to mains drainage, the Klargester Biodisc provides a reliable, efficient and environmentally safe solution for your sewage disposal needs.
It is ideal for locations where a septic tank will not meet the required standards and discharge is to groundwater through a suitable polishing/percolation filter.

In 2005, the BioDisc underwent 40 weeks of stringent testing to assess its treatment efficiency as part of Klargesters commitment to meet the new European Standard for small
treatment plants. After delivering exceptionally high levels of pollution removal
(95%) under varying loads and conditions, the BioDisc was awarded its Performance Certificate, and certified to European Standard EN 12566.
The test report also highlighted that the

  • BioDisc operates without noise or odour
  • Maintenance requirements are low with good access
  • No technical or mechanical faults
  • Low power consumption at 1.3kw/d - approx
  • 15-20 cent per day
  • Low sludge build up and large storage capacity

Designed for Quality, Reliability and peace of mind Klargester has pioneered the development of packaged treatment plants with many thousands of successful installations worldwide. The Biodisc is robustly constructed from corrosion free materials, designed and manufactured in accordance with BS 6297. The Biodisc has been awarded British and Irish Board of Agrement Certification. Klargester is an accredited company under BS EN ISO 9001:2000 quality management systems.

The Klargester Biodisc is the only packaged sewage treatment plant utilising Rotating Biological Contactor technology for small domestic applications. This process offers inherent cost and performance benefits. The Klargester Biodisc is a high performance package treatment plant which, in normal domestic situations, will produce effluent qualities of better than 15mg/l BOD, 25mg/l SS and 15mg/l ammonia.

Biodisc has the lowest running and maintenance costs of any packaged treatment plant in its class. The single home unit requires an annual de-sludge only, the motor rating is 50 watts
and routine mechanical maintenance is minimal.

Lowest running costs combined with the quality and durability of the equipment - particularly the drive motor which has a considerably longer service life than the pumps and blowers fitted to competitive units - all add up to a significantly lower lifetime cost for the BioDisc.

Central to the operation of each 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. Wastewater and sewage flows into the primary settlement zone 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 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 for further treatment any solids remaining are settled out in the final settlement tank. The quality of the resultant liquor allows discharge close to or into 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.

Klargester have a dedicated service division providing a unique and comprehensive care package both before and after supply. Throughout Ireland our team of service engineers is always on hand to ensure that Klargester products provide their owners with a long and cost-effective life.

A full initial 12 month warranty covering all mechanical and electrical components against malfunction accompanies every Biodisc installed and maintained in accordance with the manufacturer’s instructions provided the unit has not been subjected to damage or abuse
