Not cool enough in summer. Not warm enough in winter. Guests staying at a prestigious country club in New York state complained regularly about the air conditioning and heating of their luxury suites and apartments. By Martin Dingman, Product Manager, Siemens Industry Inc.
The Environmental Protection Agency (EPA) administers the Safe Drinking Water Act (SDWA), which provides for the enhancement of the safety of public drinking water supplies through the establishment and enforcement of nationwide drinking water regulations. Congress gave the primary responsibility for establishing regulations to the U. S. EPA. Until 1990, the EPA administered a certification process for chemicals, including phosphates, to be used for potable water treatment. By Randy C. Turner, Technical Director, Swan Analytical USA
Air stripping and granulated activated carbon were applied at different points in the distribution system to evaluate effective removal of disinfection byproducts (DBPs). By Chandra Mysore, Ph.D., James Fletcher, Bill Roberts, and Mark Xerxis, GHD Inc.
There are many potential issues that can affect a utility’s water network, including leakage and contamination. Having the ability to predict potentially harmful events that could occur can help utilities not only save money, but ensure that clean water is delivered efficiently and affordably. Download the full case study to read more of the story of how one utility found a solution to its growing distribution network problems.
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.
In January 2014, the city of Meadows Place, Texas, became the first city in Fort Bend County to fully convert to an Advanced Metering Infrastructure (AMI) fixed-network system. At the same time, the city also implemented a complete meter change-out for its 1,600 customers. Both projects represent large initiatives for the self-proclaimed “little city” with a population of 4,600 citizens.
Nutrient removal from wastewater is an increasingly common requirement for water resource recovery facilities (WRRF). Nitrogen and phosphorus are the nutrients being targeted.
When municipalities choose to manually feed phosphates into their potable water, this often creates an over-feed of chemicals. Learn how employing an automatic-dosing phosphate analyzer can reduce operating costs and improve reliability.
The City of Coeur d’Alene, Idaho, had been using a drive-by Automatic Meter Reading (AMR) system to read all of its meters since 2010, but according to Rob Stark, utility supervisor for the City of Coeur d’Alene Water Department, it wasn’t realizing the full benefits with its existing system.
Some wastewater applications require chlorine residuals greater than can be effectively monitored using DPD due to the oxidation of the Wurster dye to a colorless Imine. Such applications include industrial wastewater processes that inherently have a high chlorine demand thereby requiring a more robust monitoring method.
The pressures of supplying a growing global population mean that the world’s water supplies need to be managed more closely than ever.
The water municipality at a mid-size city in the Western region of the U.S. serving a population of about180,000 people needed to address a chlorine disinfection system problem at one of its water treatment plants.
Polycyclic Aromatic Hydrocarbons (PAHs) are a large group of organic compounds found naturally in the environment. PAHs are monitored by the US Environmental Protection Agency due to their carcinogenic characteristics.
In 2012, Americans consumed well over 79 billion servings of tea, which is just over 3.60 billion gallons.
Hexanal is one of many well-documented aromatic components that contribute to flavor and aroma in common consumer food products containing omega-6 fatty acids. Hexanal content is also used to measure the oxidative status of foods rich in omega-6 fatty acids.
Water quality laboratories across the nation are faced with both a rising level of water quality awareness amongst the general public, as well as rising costs in water quality monitoring. As a result, laboratories are looking for more efficient ways to provide higher quality monitoring.
Numerous compounds contribute to changes in beer flavor as it becomes stale. One of these compounds, (E)-2-nonenal, has been investigated as a major source of the papery/cardboard flavor that develops in aged beer.
The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.
Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.
The BREW Tank was a series of brief product pitches in the vein of television’s popular reality competition “Shark Tank.”
While advanced metering infrastructure (AMI) may seem like the wave of the future, there are some things about the revolution that can be intimidating. Many utilities might like more metering information and digital management, but have serious questions about how such a system will fit into current processes and affect the bottom line.
In an industry with more than its share of startup tech companies, Lux Research identifies innovators in water quality analytics that are poised to make a splash.
Water distribution might sound as easy as passing water through pipes, but good municipal managers know better. With failing infrastructure rampant and an increased focus on operational efficiency, water quality, and conservation, distribution systems demand oversight and optimization.
Doctors have their stethoscopes, plumbers have their wrenches, and accountants have their calculators. More often than we would care to admit, professionals are only as good as their tools. For water utilities, staying on top of water quality means taking advantage of the cutting edge in sensor technologies.
