High Disinfection By Products are now a significant issue in treating municpal water. They are commonly referred as TTHMs and HAAs. The primary cause of them is the interaction between chlorine and organics. Water Solutions Unlimited has treatment programs that help lower the organic load and chlorine feed in a system. This will lead to lower Disinfection By Products.
A 3 MGD Facility began working with Water Solutions Unlimited in 2010. In 2009, their TTHMs were 75 and their HAAs were at 60 during the 3rd Qtr.Their numbers were at or near the limits during the probematic 3rd Qtr of testing every year. In 2010 one of the programs was implemented and the results are shown below:
Year (3rd Qtr) TTHM HAA Year (3rd Qtr.) TTHM HAA
