WATER INSTRUMENTATION WHITE PAPERS & CASE STUDIES
A dissolved oxygen sensor ought to be simple to understand. Whether it is membrane or optically based, it gives a signal that is proportional to the concentration of oxygen concentration in water.
Utah Water District Saves Time And Resources, Improves Accuracy By Upgrading Sensors And Analyzers
Monitoring chlorine and fluoride levels in the drinking water of Utah’s Taylorsville-Bennion Improvement District used to be expensive, labor intensive, and often sensitive to interference from the variable frequency drives used to operate the chlorine injection pumps. That is, until the district upgraded to Rosemount Analytical free chlorine and fluoride sensors and analyzers from Emerson Process Management.
Chicago Suburb Ensures Highest Water Quality Year-Round, Saves On Labor And Reagents With New Chlorine Analyzers
For the Village of Lombard’s Water Division, consistently delivering high-quality tap water to the community’s nearly 44,000 residents and the businesses serving them was once quite a juggling act: constantly fixing old, temperamental analyzers; feeding reagents into the old analyzers; and staying ahead of callers complaining about “musty” water tastes and odors. Not today.
Ammonia Monochloramine Analyzer Helps Utility Control Chloramination
In chloramination, continuous online monitoring and increased frequency of measurements allow you to react faster to changes in water quality. The Bachman WTP in Dallas, TX tested the new Hach 5500sc Ammonia Monochloramine Analyzer against other lab and process analyzers. Read the full case study to see how the increased frequency of the 5500sc AMC measurements allow the Bachman Plant to react faster to water quality changes and further optimize their chloramination processes.

Online TOC Analysis In The Drinking Water Treatment Process
In 1974 the Congress of the United States passed Public Law 93-523; the Safe Drinking Water Act (SDWA) to protect public health by regulating the nation’s drinking water supply and protecting sources of drinking water. The SDWA first went into effect on June 24, 1977 and has been amended multiple times.
North Carolina Treatment Plant Eliminates Taste And Odor Issues With Ozonation
Enactment of the Long Term 2 Enhanced Surface Water Treatment Rule and the Stage 2 Disinfectant-Disinfection Byproduct Rule (D/DBPR) will require both large and small drinking water utilities to reduce total organic carbon (TOC), Cryptosporidium, and disinfection byproducts (DBPs) in the treated drinking water distributed to the public.
Clari-DAF® System Provides Effective TOC Removal For Cambridge WTP
To ensure treated water complied with the most stringent drinking water standards, including the Environmental Protection Agency (EPA) Stage 2 Disinfectants and Disinfection Byproducts Rule (State 2 DBPR), the City of Cambridge, MA, WTP decided to implement a robust multibarrier treatment solution.
Portable Parallel Analysis: Streamlining Distribution System Water Testing
A Water Quality Specialist used the Hach SL1000 Parallel Portable Analyzer (PPA) to test 6 parameters simultaneously – all within about 8 minutes. Previously, the procedure took 20 minutes just for one parameter.
Optimize Energy And Resource Usage
Through the implementation of a WAGES (Water, Air, Gas, Electricity and Steam) monitoring solution, a brewery was able to optimize energy and resource usage while boosting capacity to meet the demands of U.S. customers. Water usage costs were reduced by 28%; the brewery’s carbon footprint was reduced creating a savings of $2 million/year from CO2 recovery; compressed air usage was reduced by 15%; and fuel oil costs were reduced by $34,000.
Advanced Metering Analytics And Hi-Res Ultrasonic Meters Create A Winning Combination
When Waterworks District 3 of Beauregard Parish, La., began to research new water meters to replace its aging system, it didn’t take long to decide that the BEACON AMA managed solution was the right fit.
Mass Or Volume? A Weight Off The Bottom Line
Confusion often arises over the difference between mass and volume flow measurement and when a particular measurement should be applied.
Water District Solves Metering Problem: Non-Intrusive Ultrasonic Technology Provides Accurate Measurements
The Jacksonville JEA water district had a problem. Its measurements showed that it was distributing significantly more water than it was removing from its wells.
Municipality arrives before the water bill to alert customers of unusual spikes in usage.
