| Details: | 05.03.21 - Received a report from Dan informing me of his assistance provided to Weiss Estates Water system. The circuit rider contacted Corrine by phone and discussed many options the system could pursue both in regard to the GAC efficacy and also the optimization of the disinfection contact system used at Weiss Estates Water System. GAC Reactor: Dan suggested adding a meter and test ports before and after the GAC filter to test for TOC removal and to record total volumes passing through the filter to determine efficacy. Dan also reported that it is possible that by adding a manufacturer approved coagulant prior to the membrane, that more TOC could be removed. This could lower TOC prior to the GAC filter, thus extending the life of the carbon media. follow up actions by circuit rider: The circuit rider is planning on assisting the system with a CT Study to help optimize the contact time and chlorine residual in an effort to minimize DBP formation. No expected time frame noted on Dan's report. |
