Webinar: Get Ready for Summer: Disinfectant Residual Control in Water Distribution Systems
This webinar provided water system managers, operators and engineers a practical understanding of the conditions, chemistry and science behind affecting positive control of both chloramine and free-chlorine levels in water distribution systems. Importantly, the second half of the seminar presented a suite of proven technologies that can be employed to automatically control disinfectant residual levels in real-world water distribution systems.
