Extended Aeration

Extended Aeration is a type of activated sludge process with no primary settling and longer aerobic detention time to generate less excess sludge overall.
It is a biological treatment process, which is able to produce high quality effluent at a reasonable operating and maintenance costs.
The Extended Aeration process is widely used by large cities and communities where large volumes of wastewater must be treated highly economically.
Extended Aeration plants are good choices too for isolated facilities, such as hospitals or hotels, housing developments and even individual residences.
Following completion of the wastewater treatment plant, an ongoing after-sales service is provided through evaluation and analysis of plant data to ensure that the plant is operating at its optimum performance capability.
In addition, accessing the process control system and SCADA through a web link enables us to provide the client with a remote online monitoring service.

The reason for this is their ability to produce a high quality effluent for the price.
Other advantages of the Extended Aeration process are its stability, the ease of installation and operation of systems, the low operating and maintenance costs, handy operation the low sludge yield and the odourless operation.
