Abstract

See full text

Combined Sewer Overflow (CSO) events require certain minimum treatment, before discharge, according to EPA regulations. However, these events are infrequent, and CSO treatment systems remain idle most of the time. Tertiary filtration is typically used to polish off the secondary treated water in order to remove suspended matter, phosphorous, etc. Tertiary systems are usually designed to handle design flows and remain active most of the time. These are two independent unit operations requiring major capital investment and operational expense. According to this invention an interchangeable system is able to switch a tertiary treatment reactor back and forth between two applications ensuring seamless operation, smooth transition and significant cost savings for treatment facilities.
