> Capital, operation and maintenance costs are significantly lower than a conventional activated sludge system of equal capacity

> Small footprint requires less land for installation

> Microprocessor control requires less operator attention, easy to operate

> Larger operational flexibility than most conventional systems

> Better at handling organic loading and flow fluctuations, and is suited for sites that have a wide range of inflow and/or organic loadings

> Pre-Engineered and Pre-Fabricated, easy to transport and install as they are shipped in one 20' shipping container, and only minor connections required

> Odour free

> Low waste sludge production due to long sludge ages

> No sludge bulking problem as often found in conventional systems

> Little operation and maintenance problems
