Field Testing for Residual Chlorine Application Note:Field Testing for Residual Chlorine Essential indicator of water quality Residual disinfectant concentration is an essential indicator of the health of the drinking water distribution system. A measurable disinfectant residual indicates that the microbial
Wastewater effluents containing more than 1 PPM of ammonia, often result in a chlorine residual that is more than 90% monochloramine. Direct measurement with a submersible sensor can provide a dependable monitor without all the sampling and chemicals associated with total chlorine measurement.
Today, water is becoming even more of a precious commodity than ever before, which is why it is of the utmost importance that your customers drink the highest quality of water. Using chlorine is one way water treatment facilities keep water free of bacteria and harmful organisms, but too much chlorine in the water supply can also be hazardous if not reduced before coming out of your customers’ tap.
