plants. Sewers collect the wastewater from homes, businesses, and many industries, and deliver it to plants for treatment. Most treatment plants were built to clean wastewater for discharge into streams or other receiving waters, or for reuse. Years ago, when sewage was dumped into waterways, a natural process of purification began.
The Extended Aeration process has a 24 hour aerobic retention time which results in the generation of less excess sludge. Extended Aeration is a biological treatment process, which is able to produce a high quality of effluent. This process is widely used and recommended for installations remote of city sewers.
