Primary effluent is passed into large aeration tanks, pumped with air, and mechanically agitated to allow floc growth. The effluent is then passed into a settlement tank, where the sediment is called activated sludge and is the secondary effluent.
يتم تمرير التدفق الأولي إلى خزانات تهوية كبيرة، حيث يتم ضخه بالهواء وتحريكه ميكانيكيًا للسماح بنمو التكتلات. ثم يتم تمرير التدفق إلى خزان ترسيب، حيث يُطلق على الراسب اسم الحمأة المنشطة وهو التدفق الثانوي.
