Online Monitor for Low-level THM Detection in Treated Wastewater

The City of Paso Robles, California used a new online THM monitor capable of low-level real-time detection of DBCM and BDCM to help characterize and monitor THMs their treated wastewater for ground water recharge use. The high frequency of reliable and accurate THM data provided by the online instrument proved essential to the City’s DBP strategy to obtain regulatory compliance with NPDES permit levels.

Online Monitoring of THMs at Scottish Water

For more than five years Scottish Water has relied on the reliability and accuracy of the online THM-100™ monitor to continuously monitor THM levels at a number of their facilities. The online THM monitors have allowed Scottish Water to consistently monitor, maintain, optimize and respond to any on-going THM concerns in a very timely fashion. The THM-100 proved especially valuable at the Tullich WTWs when the facility tested and implemented an aeration system to further minimize THM formation.

Santa Cruz Adopts THM Analyzer for DBP Management

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 systems THM levels.

Arizona Facility Uses Ammonia-Laden Centrate for THM Control

The Pima County Regional Wastewater Reclamation Department is using the THM-100™ to optimize its chlorine injection process. The Tres Rios Water Reclamation Facility is using ammonia-laden centrate 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. The complete article as published in the September 2015 issue of Water & Wastes Digest can be read here.

SafeGuard™

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