The EPA’s guidance documentation “3T’s for Reducing Lead in Drinking Water in Schools and Child Care Facilities: Training, Testing, Telling” recommends for schools to routinely test their facility’s drinking water, with a focus on lead levels in drinking water fountains.
Confusion often arises over the difference between mass and volume flow measurement and when a particular measurement should be applied.
Whether it is dining out less often or putting off that new car purchase just a bit longer, it seems that doing more with less is something many of us have become accustomed to over the last few years. Consumers are not the only ones feeling the pinch. By Doug Johnson, Emerson Process Management Power & Water Solutions
Electromagnetic flowmeters, also known as mag meters, are popular and proven devices for flow measurement of electrically conductive process fluids and for volumetric filling machine applications. Of prime importance to a mag meter’s accuracy and long term performance is the condition of the metering section of the flow sensor. By Dipl.-Ing. F. Hofmann and Dipl.-Ing. B. Schumacher, KROHNE Messtechnik GmbH Co KG Duisburg, Germany
Mid-to-large size facilities and campuses inevitably have hundreds of flow instruments to monitor, maintain, and repair. For a reliability engineer, ensuring that all instrumentation meets ISO 9000 or similar standards is a time-consuming responsibility. By Matthew J. Olin, President & CEO, Sierra Instruments, Inc.
When considering the current state of the water and wastewater industry, water metering is an important part of the conversation.
A municipal wastewater treatment facility located in Louisiana was having problems with a clamp-on ultrasonic flowmeter that was supplied by a Siemens competitor.
Advancements targeting the challenges related to a flooded meter pit environment have occurred slowly over the years, with limited success.
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.
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.
New tools are being developed for worst-case drinking water scenarios: chemical, biological, radiological, and nuclear (CBRN)-related contamination.
The Government Accountability Office recently assessed technologies that can potentially save the U.S. from water stress, focusing on distribution efficiency and the treatment of nontraditional sources. We provide a snapshot of GAO’s findings, including technology pros and cons, “readiness” rates, and levels of adoption.
As critical gateways to the Internet of things (IoT), sensors are sure to have a massive social and economic impact globally within the next decade.
Water 4.0 is a concept that has recently been raised as the “future” of the water industry …possibly. Apart from being a paraphrase of Industry 4.0, the questions have to be asked: What is it, and what does it have to do with the way the water industry operates in its current state?
