Monitoring Wastewater Effluent using a Rapid, Automated Detection System for E. coli and Fecal Coliform Bacteria

Abstract This study was done to characterize the use of the TECTA™ system for rapid, automated detection of Fecal Coliform (FC) and E. coli (EC) bacteria in a combined test, with incubation at 44.5 °C. It provided automatic detection without the need for a technician at the end of the test, and results were logged and transmitted by e-mail. The TECTA test was performed alongside ...
