<emphasis role="bold">HIGH-RATE CLARIFICATION</emphasis>High-rate clarification combines techniques of chemically enhanced particle settling and solids contact/recirculation with lamella plate and tube settlers to achieve rapid settling. Very high settling velocities combined with rapid flocculation kinetics can reduce required process footprints to less than 10% of conventional primary treatment (Jolis and Ahmad, 2001). Although high-rate clarification has been used in Europe for some time, its use in the United States is more recent. Wet-weather treatment strategies have been implemented at many facilities because of evolving regulations that require reductions in CSOs and SSOs and some d…
