EXTENDED AERATION SYSTEM
The Extended Aeration (EA) system is one of common Biological system used to treat domestic wastewater due to its functionality and simplicity. The treatment plant provides the proper environment, sufficient oxygen and other elements which allow the bacteria to consume the organic matter and to live and multiply within the treatment plant. In this way the aerobic bacteria and microbes decompose the sewage and waste to a stable form.
Our Extended Aeration plants provide a low cost, odour and nuisance-free Sewage Treatment Plant that produces a high degree of treatment. Extended aeration treatment plants are used worldwide to provide simple and effective wastewater treatment.
Advantages of Extended Aeration System.
- Easily maintained mechanical work.
- Extended aeration processes are often better at handling organic loading and flow fluctuations, as there is a greater detention time for the nutrients to be assimilated by microbes.
- Systems are odour free, can be installed in most locations, have a relatively small footprint, and can be landscaped to match the surrounding area.
- Extended aeration systems have a relatively low sludge yield due to long sludge ages, can be designed to provide nitrification, and do not require a primary clarifier.
