By definition, this reactor is a totally homogenous tank where micro-organism, oxygen and residual substrate concentrations (figure 11) are identical at all points in the tank. WebThe result is a system which offers significant cost reduction compared to activated sludge and granular carbon treatment options. The addition of the powdered activated carbon stabilizes biological systems against upsets and shock loading, controls color and odor, and may reduce disposal costs while removing soluble organics.
