In 40 years, Endress+Hauser has become market leader in electromagnetic flow measuring technology
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 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.
The North Shore Water Commission located in Glendale Wisconsin is a conventional water treatment facility that receives its influent from Lake Michigan. At the intake, chemical treatment is applied for mussel control and the water is pumped to the treatment plant 1 mile away. By Kevin Forsman
For many years, ultrasonic metering has been utilized for large scale liquid and gas measurement. However, it is a relatively new technology for small meter applications — particularly those designed for potable water.
Nutrient removal from wastewater is an increasingly common requirement for water resource recovery facilities (WRRF). Nitrogen and phosphorus are the nutrients being targeted.
Averting regulatory violations and fines. Avoiding system disruptions. Maintaining effective monitoring in complex applications. How do you tackle these kinds of age-old plant monitoring problems?
Like the old saying goes, give a man a watch and he always knows what time it is. Give him two watches and he never knows the correct time. What do watches have to do with pH? In this article, we will tie the analogy of accurate time to pH measurement and show how to make more accurate, dependable and believable pH measurements by using three pH sensors.
There are many well documented flow meter technologies that are essentially trying to accomplish the same thing: measure fluid flow rate. Some of the technologies that are entrenched in the market, such as flow meters that utilize differential pressure as the measurement principle, are well understood by customers. Thermal mass flow meters however, such as the Magnetrol® Thermatel® TA2, are a rapidly growing technology that is continuously evolving.
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.
The City of Alliance Ohio’s water system has experienced annual Taste and Odor (T&O) events since the mid 1950’s, when the first of two reservoirs, Deer Creek Reservoir, was placed into service. Nutrient contaminants, in particular phosphorous, in the watershed accumulate in the reservoirs causing algal blooms. By Terry Keep of TrojanUV, Said Abou Abdallah of Arcadis, and Dr. Dean Reynolds, Department of Water Treatment City of Alliance, Ohio
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.
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.
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?
Get to know the basics, best practices, and importance of flow meter calibration from an industry expert.
There are two practices that can help water utilities identify broken segments of their systems and reduce the nonrevenue water that results. Amidst the nation’s current infrastructure crisis, they are exercises worth considering.
Taking pH measurements may be the most common water quality testing performed around the world. From backyard pools to treatment plants serving millions, it has long been a reliable method of detecting red flags in water quality. But with rapid developments in sensor technology, is there room to innovate on such a routine practice? Water Online spoke with Thomas Roemer, the business development manager for KROHNE about the company’s efforts to do just that.
While it took a series of egregious bungles on several different levels to plunge Flint into the crisis, perhaps the most unforgivable lapse has been government officials’ negligent water testing.
