The recirculation may be either internal or external to the clarifier and often results in higher throughputs, albeit at the expense of greater mechanical complexity. By way of example, internal recirculation is used in the Eimco E-™ high-rate clarifier, which has a typical diameter between 4 and 12 m (see Figure 1.8).
