Virtually Inaudible – High performance diaphragm blowers are used and externally housed achieving a virtually silent operation.

Odourless – The system is hermetically sealed, coupled with a market leading treatment performance eliminates odour.

MBBR Technology – Moving Bed Biological Reactor (MBBR) systems are self-cleaning and unable to become blocked through channelling unlike most fixed film media systems.

Market leading performance – Producing an excellent 96.6% pollutant removal level, the final effluent can be directly discharged into a stream or soakaway.

Low Maintenance Costs – Chamber one capacity is as much as 66% larger than other plants, making desludging intervals up to three times longer saving the owner significant costs.

Power Failure Default – The system keeps performing as a septic tank in the event of a power failure.
