The treatment capacity of an existing wastewater system fitted with conventional (air based) Jet Aerators can be increased substantially by converting aerators to pure oxygen operation. This is usually a simple and inexpensive conversion.

The rate at which oxygen dissolves is proportional to the purity at which it is used. By changing from air to oxygen the purity increases five times giving much higher oxygen transfer rates.

A further benefit is the much reduced VOC stripping from the effluent system due to much lower volumes of gas leaving the basin.
