Wastewater Treatment Plants facing stringent effluent permit limits for ammonia, nitrogen and THMs can benefit from using online THM analyzers. Measurement of THM levels in the effluent prior to and following the chlorine injection point is necessary as utilities work to reduce DBP formation while minimizing nitrogen and ammonia levels. The introduction of an online THM analyzer for use in wastewater applications now enables WWTPs to characterize THM values in real-time.

In a newly released Water Research Foundation (WRF) report, TTHM concentration results from the THM-100™ analyzer yielded excellent results. Throughout the duration of the demonstration testing, results obtained from the AMS THM-100™ analyzer were within ± 10% of laboratory results. In addition to the TTHM concentrations, the individual THM species concentrations also matched very well between the AMS instrument and the laboratory.

Evaluation of the field TTHM analytical instruments demonstrated that these instruments are easy to install and operate, can generate TTHM results quickly, and most importantly accurate and precise.

Real-time data and analytical information from online instruments help utilities comply with water quality regulations. The complete article detailing how online water quality instruments are poised for growth was published in the March/April 2015 issue of World Water. 

An aeration system has been installed in San Jose Water Company’s 12 million-gallon water storage tank to keep dwindling water supplies free of contaminants and possible carcinogens. As organic matter in water sources, like drying rivers and lakes, is becoming more concentrated, according to the water company, there has been a growing concern about levels of trihalomethanes, or THMs.

The buying and selling of treated water is common practice in the United States. Consecutive systems (CS) — public water systems that buy or receive some or all of their finished water from one or more wholesale systems (WS) — are responsible for serving nearly one-third of the water customers in the U.S… read the rest of the article by Rick Bacon the CEO of AMS.

As long as instrumentation is selected, installed, commissioned, and maintained properly the data that it can give is invaluable to the water industry. However, there are a number of barriers in the way… read the rest of the article and a response from Rick Bacon the CEO of AMS.
