Control DBP Formation in Wastewater Effluent with Online THM Analyzer
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.
The THM-100™ online monitor provides automated, unattended measurement of THMs. Leading drinking water utilities and engineering groups have come to value the high frequency and reliable data provided by the THM-100; enabling a firm and immediate understanding of THM values so they can better anticipate problems and maintain optimal treatment conditions. The THM-100 is cited as the key element in real-time THM data gathering in three ACE15 technical session presentations.
The City of Birmingham will present Online THM Analyzer Used to Optimize Chlorine Disinfection Process and Minimize DBP Formation in Alabama in the TUE15
Corona Engineering will present High THMs? Strip‘em Away! Full-Scale Demonstration of Two Aeration Strategies for Removal of TTHM from Treated Water in the TUE38
San Jose Water Company and Pax Water Technologies with Utility Services Group will present Energy-Optimized Large-Scale THM Removal: Results from a 12-MG Reservoir, San Jose, California in the TUE38
During ACE15, AMS will also unveil their novel SafeGuard™ online trace metals analyzer for chromium VI and selenium. The SafeGuard analyzers discriminate between selenite (Se4) and total inorganic selenium and chromium-6 and total chromium; providing complete process control to proactively manage, control, mitigate and remediate trace metals contamination.
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.
Online Water Quality Instruments Poised for Growth
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.
PAX Water Installs In-Tank Aeration at San Jose Water Co.
PAX Water Technologies and Aqua Metrology Systems unveiled the installation of an in-tank aeration system at San Jose Water Co. The system, installed by Utility Service Group, is being deployed in a 12 million-gal water storage tank to maintain high water quality during the drought.
Large aerator installed in San Jose water storage to clear out possible carcinogens
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.
PAX Water Technologies Unveils In-Tank Aeration Install at San Jose Water Company
Richmond-based PAX Water Technologies and Sunnyvale-based Aqua Metrology Systems today 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.
