If you’re in the business of managing a water system – whether drinking water, wastewater or water used for industrial purposes – a luminometer can make your job easier.
New tests recently performed by DM Petroleum Operations Company with the FPI Mag® Flow Meter from McCrometer continue to confirm the flow meter’s accurate performance and reliability on two rugged Texas brine disposal lines supporting the U.S. Strategic Petroleum Reserve (SPR).
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.
Turbidity is a principal physical characteristic of water and is an expression of the optical property that causes light to be scattered and absorbed by particles and molecules rather than transmitted in straight lines through a water sample. By Randy Turner, Technical Director, Swan Analytical USA
Russellville water treatment plant is a surface water plant using traditional clarification, filtration, and treatment. The plant historically has used traditional contact turbidimeters that employ tungsten lamps that required quarterly maintenance, but replaced their turbidimeters with Swan Turbiwell turbidimeters in 2012. Read the full report for a comparison of the performance of the Swan Turbiwell to the previously installed turbidimeters.
Water and wastewater facilities are increasingly looking to ozone disinfection. A strong and indiscriminant oxidant, ozone can effectively address treatment issues with THMs and DBPs in the disinfection process. Ozone disinfection is also a proactive step toward addressing future rules on endocrine disrupting compounds (EDCs) and other trace organics at both water and wastewater plants. While there are many aspects to ozone disinfection system design, the single most important factor in project success is a thorough understanding of your facility’s ozone demand profile. This article provides an outline of the key factors to make your ozone demand test -and ozone project- a success. By Thoram Charanda and Louis LeBrun
Thermal dispersion switches use similar principles as thermal mass flow meters. Fluid carries heat away from the probe tip reducing the temperature difference between a heated resistance temperature detector (RTD) and a reference RTD.
Fluid catalytic cracking (FCC) is a major unit operation in refineries around the world. FCC is used to convert lowvalue, high molecular weight feedstocks such as shale oil, tar sands oil, and coker gas oils into lighter, high-value products by “cracking” C-C bonds.
As interest in biogas grows, more attention is being paid to measuring biogas flow, which has long been a problem area in process measuring technology. By Dick Laan, Ultrasonic Flow Product Manager, and Rick Lowrie, Water & Wastewater Industry Manager, KROHNE, Inc.
Badger Meter has and will continue to manufacture and provide products that meet the requirements of current and future lead-free standards. This white paper discusses these changing industry needs both as they relate to Badger Meter products and to water utilities in general.
Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.
Electrical conductivity is the most convenient method for testing RO water quality and membrane performance. Pure water is actually a poor electrical conductor. The amount of ionized substances (salts, acids, or bases) dissolved in water determines its conductivity. Normally, the vast majority of the dissolved minerals in tap, surface or ground water
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.
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.
Though they all must support routing functionality, some devices do it better than others.
Routing consumes more energy, so the lifetime of the battery will be affected. Therefore, a device with a battery that is inexpensive, has a long lifetime, and is easy to change would be ideal. With all this considered, a WirelessHART temperature transmitter is a suitable option to operate as a repeater.
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.
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.
The nearly 16,000 people in Calhoun, GA, rely on two drinking water treatment facilities — one that pulls its water from a river and another that pulls from groundwater — that process about 9 MGD. The turbidity of the river’s water can fluctuate dramatically, so the operators rely on the surface water treatment plant’s turbidity analyzers to ensure that they are serving the population as they should.
Mobile-enabled geographic information systems (GIS) herald a new age for bacterial source tracking, allowing increased stakeholder involvement, more informed decision-making, and enhanced water quality.
Utilities using ozone for disinfection must meet strict regulatory requirements for bromate. MilliporeSigma has been in the business of improving analytical equipment to make life in the lab more efficient and cost-effective for many years. Water Online spoke with MilliporeSigma about a new method for measuring bromate in drinking water.
Utilities are under constant pressure to reduce costs, meet regulatory requirements, and improve sustainability. Finding the best way to meet these goals is a constant challenge. Endress+Hauser has been helping water and wastewater utilities achieve their objectives for many years, and spoke with Water Online to discuss how to save
energy in today’s wastewater treatment facilities.
Many treatment facilities test for chemical oxygen demand on a regular basis. Some laboratory test methods can be time consuming and expose technicians to toxic chemicals. In addition, interference from components in the samples may affect the test results. MilliporeSigma is a global leader in the life science industry and has produced test kits to measure numerous analytes. Water Online spoke with MilliporeSigma about advances in measuring chemical oxygen demand
