This 50 person Klaro Professional sewage treatment plant from Graf boasts four injection moulded underground tanks and benefits from an advanced control panel.

The system works according to the principle of SBR lifting technology. No live parts need to be installed in the tank. All movement processes are performed by three air lift pumps, which are operated using a compressor. The compressor also provides the plate ventilator on the bottom of the SBR reservoir with air. The compressor and all other technical components are low maintenance, offer power failure recognition and are stored in an internal switch cabinet, which can be installed in the plant room of the house.

Key benefits:

  • No moving parts inside the tank, easy to install, easy to maintain
  • Low energy consumption
