Technology coagulant chemicals and combining with disinfectants such as chlorine and chloramine to create toxic disinfection by-products (DBP's). Increasing regulations are coming into place to include more regular monitoring and control of organics. The traditional method for testing organics is total organic carbon (TOC). However, TOC testing is extremely expensive, complicated and time consuming, and for many applications is not the best organic test. Unlike TOC testing, the use of spectrophotometric organic testing allows more specific information about the reactive portion of the organic material in the water to be determined. This makes spectrophotometric analysis a more valuable indicator of the organics that are going to be problematic. A new generation of monitoring equipment offers greater control of plant processes. can now be achieved. Installation of these new monitoring devices at key locations within the distribution system can allow utilities to spend more wisely and gain the real-time ability to immediately detect a contamination event, warding off extremely expensive and harmful consequences. Some of the latest real-time analyzers are significantly more sensitive than the lab spectrophotometers due to technological advances, includ- ing the ability to use very long pathlengths. This allows some real-time spectrophotometric ana- lyzers to be much better suited to an application that requires high sensitivity to contaminants such as the requirements for dis- tribution system monitoring. This strengthens the value for utilities to be able to move forward with security monitoring applications. TOC Alternative For Organic Analysis Spectrophotometric analysis and especially UV254 analysis offers a far lower cost alternative to tradi- tional TOC monitoring not only in the upfront capital investment, but also due to the very low mainte- nance requirements of spectropho- tometric instrumentation, saving users money and time. Many plants understand the benefit of organic analysis since organics in water have many negative consequences. Typical negative effects of organics in municipal applications include causing taste and odor, providing food for bacteria, consuming In many cases, this type of application only requires UV254 analysis. UV254 organic analyzers are a fraction of the cost of TOC analyzers, do not require any consumables, and have very low maintenance. The cost savings and overall benefits that a plant can see from comparing the purchase of a TOC analyzer to a UV254 analyzer are clear and represent a great example for how plants can spend more wisely in today's more budget conscious environment STOP WATER LOSS Complete Leak Surveys Service both sides of the meter.
