A Simple Method for Organic Carbon Determinations and Its Application to Enhanced Coagulation Requirements

摘要

With the implementation of the D/DBP rule (1), drinking water facilities in the United States that use surface waters and conventional filtration treatment are subject to organic material removal rules. The D/DBP rule requires 15-50% total organic carbon (TOC) removal, depending on source water TOC and alkalinity concentrations. The rule allows an alternative TOC removal requirement based on jar testing. TOC removal is accomplished through either enhanced coagulation (EC) or enhanced softening (ES) treatment techniques.
