Simple and cost-effective

With the development of the Picobell Moving bed system, a GRAF treatment system is now available which has simple technology and, at the same time, offers high cleaning performance. The system‘s technology comprises just one air compressor, a compressor guard, power failure recognition, a pipe ventilator, sludge removal and the carrier material. The system works completely without electronic control, pumps and magnetic valves. A further advantage of the Moving bed system is that the high cleaning performance is also maintained with strong underfill.

• 15-year warranty on sewage reservoirs and for Picobells
• 3-year warranty on technology

Cost-effective and well thought-out

The compact and quiet air compressor is integrated in compact housing. It reduces the system's energy consumption to a minimum and is easily installed in the plant room of the house. Additionally, the system does not need consistent integration of live technology in the tank. All the movement processes are performed by the whisper quiet air compressor.

Maintenance

The need for maintenance is kept to a minimum. This is mainly due to the permanent self-cleaning of the carrier material and the modern control technology. Thus, maintenance just consists of regular function testing and sludge removal.

Self-cleaning Picobells

The carrier material is constantly mixed in the wastewater through aeration. During the mixing and swirling these will get automatically cleaned. The possible degradiation with the time of the cleaning performance belongs now to the past. The biofilm, which is responsible for cleaning the wastewater, settles on the approx. 3 cm wide Picobells. The unique, lamellae-shaped design gives the carrier material a maximum surface and this is where the cleaning power lies.
