Variations of your activated sludge method include extended aeration, Call stabilization, and high-purity oxygen aeration. Extended aeration and get in touch with stabilization systems omit the main settling phase. They can be economical for treating tiny sewage flows from motels, universities, as well as other comparatively isolated wastewater resources.
