This 14 person Klaro Professional sewage treatment plant from Graf boasts a robust injection moulded underground tank. 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.
