Report: Ammonia-Laden Centrate Used for THM Control at Tres Rios WRF

The Pima County Regional Wastewater Reclamation Department is using the THM-100™ to optimize its chlorine injection process at its Tres Rios Water Reclamation Facility where ammonia-laden centrate is used for THM control. The THM-100 monitor enables the facility to optimize its chlorine injection process and minimize the formation of THMs in its effluent water by providing the operational staff with immediate and accurate daily reports on THM levels.

Report: THM-100™ Yields Excellent Results in WRF Report

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.

SafeGuard™

SafeGuard™ is an automated trace metals analyzer for monitoring municipal and industrial water and wastewater. The system provides real-time, multi-stream analysis for trace metal contaminants.

SafeGuard delivers accurate and reliable results (up to 1 ppb or ± 15%, whichever is higher) with a typical measurement time of fewer than 30 minutes. An enhanced system is available with a fast turn around time of 5 minutes without compromising accuracy. The analyzer can be used to measure up to two different trace metals contaminants on the same instrument.

Trace Metals

Contaminants such Arsenic, Chromium-6, Lead, and Selenium have come under increased regulatory pressure due to their impact on public health and the environment. The ability to obtain high frequency data and adjust contaminant remediation processes in real‐time to mitigate the impact of trace metals is only made possible through the use of the online MetalGuard™ and SafeGuard™ analyzers.

Disinfection By-products

Reliable data on THM and THM Formation Potential concentrations is required to mitigate the presence of harmful DBPs and monitor the success of THM remediation processes. Accurate and real‐time data on THM concentrations is only possible with the online THM‐100™ analyzer.
