The City of Santa Cruz Water Department (SCWD) has adopted the online THM-100™ THM analyzer for DBP management. Real-time and reliable data on THM and THM Formation Potential levels within the Graham Hill Water Treatment Plant and distribution network have been provided to the SCWD by the online analyzer. The THM-100 online analyzer has aided the SCWD in daily operations and management of feasibility studies to reduce distribution system THM levels.

The Shades Mountain Filter Plant operated by the Birmingham Water Works Board (BWWB) has benefited from the real-time high-frequency data on daily trihalomethane (THM) values provided by the online THM analyzer, THM-100™. The online THM analyzer has proven valuable to THM mitigation strategy and optimization.

The Central Texas Water Supply Corporation has incorporated an online trihalomethane (THM) analyzer, THM-100™, at their WTP to help manage DBP formation. The THM-100 is a viable tool, among others, that enables plant operators to have a firm and immediate understanding of water quality leaving their plant and throughout their distribution network.

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. 

Richmond-based PAX Water Technologies and Sunnyvale-based Aqua Metrology Systems unveiled the installation of an innovative in-tank aeration system at San Jose Water Company. The system, installed by Utility Service Group, is being deployed in a 12 million-gallon water storage tank to maintain high water quality during the drought.

The Northern Kentucky Water District has purchased the online THM-100™ THM analyzer from Aqua Metrology Systems to monitor daily THM levels in their distribution network and further enable optimization of treatment processes used to minimize the formation of THMs in treated water.

An online trihalomethane (THM) analyzer, THM-100™, was installed to monitor THM levels at The Old Bridge Municipal Utilities Authority (Old Bridge MUA) serving the township of Old Bridge, Middlesex County, New Jersey. The utility learned that quarterly DBP compliance measurements are inadequate for understanding actual DBP levels within the water distribution system; since DBP levels can range significantly, even within the same day. However, through frequent and effective direct THM monitoring, as provided by the THM-100 analyzer, they could establish a baseline and optimize DBP management processes managing compliance to the Stage 2 DBP Rule.
