• The existing Rotating biological Contactor was not operational

• Continual shaft, chain, sprocket and bearing failures were the norm

• Advanced corrosion of the rotor was evident

• The media had broken up and was falling off the rotor

• A new RBC, with a epicyclic geared motor was supplied

• New bearings and media were supplied along with a new shaft and HDG steel framework

• The new rotor now requires a lot less maintenance as the new geared motor no longer uses chain drives.

• The gearbox is generously sized and can handle restarts from power outages

• The new media is arranged in replaceable modules such that individual modules can be replaced without replacing the entire media pack
