Proper operation of water treatment processes depends on accurate flow measurements. Also, flow data is often required by regulatory agencies.
Many thermal mass flow meters are of the insertion type. As a starting point, proper insertion depth and straight run per the manufacturer’s recommendations should be adhered to.
Yorkshire Water produces 1.3 billion liters of clean water and treats one billion liters of water in its waste water networks every single day. The company has 686 treatment facilities spread across northern England and 83,000 kilometers of water pipelines, which is enough to circle the earth twice.
For many years, the Miami-Dade Stormwater Utility has been using Bristol Babcock controllers and proprietary HMI software to monitor and control a dozen remote sites across the county. By Chris Little
A landfill operator’s leachate treatment plant in Missouri required pH reduction following lime-softening and prior to the biological wastewater treatment process. Carbon dioxide (CO2) was chosen as a substitute for sulfuric acid due to improved process control and a reduced tendency to form scale.
The Metropolitan Sewer District of Greater Cincinnati’s Wastewater Collection Division manages 3,000 miles of main sewer line and services some 200,000 individual customer sewer laterals and accounts that cover nearly 1 million residents and businesses. When things go wrong with those pipes, the division hears about it from customers loud and clear.
The city of Laredo, Texas, had been walking to read its 67,543 water meters – 59,138 residential and 8,405 commercial accounts – using a manual method that took up to ten staff on the streets nearly an entire month to read to meet a monthly billing schedule. With the dawn of advanced metering infrastructure (AMI) systems, the City began their search for the right metering solution for the department’s needs.
The Philadelphia Water Department (PWD) is a municipal utility providing a population of nearly 1.7 million people in three eastern Pennsylvania counties with integrated water, wastewater, and stormwater services. The utility is responsible for planning, design, construction, operation, and maintenance of the necessary infrastructure.
Instrumentation is heavily pushed to achieve efficiency, but it only works when you use it correctly – and many utilities don’t.
Automation and information systems represent a major investment for industrial businesses, both large and small. Long-term protection of that investment should be a significant consideration when selecting a partner and a system.
A Telemetry Expert Describes How and Why Temporary Mobile I/O Will Transform Remote Asset Management
One of the most common processes in wastewater treatment is the activated sludge method, which biologically treats the wastewater through the use of large aeration basins. This process requires the pumping of compressed air into the aeration basins where a diffuser system ensures the air is distributed evenly for optimum treatment. The energy needed to provide compressed air is a significant cost in the operation of a wastewater treatment plant.
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.
Coriolis measurement has been adopted as a default technology in many application scenarios due to its high accuracy and immunity to process variables (temperature, pressure and flow profile). However, Coriolis wasn't always widely accepted. Two applications, in particular, helped what was once a nascent flow measurement technology gain a foothold in the marketplace.
Fox Thermal Flow Meters use a constant temperature differential (constant Δ T) technology to measure mass flow rate of air and gases.
Dosing of the precipitant was adjusted manually based on the laboratory measurement value of the daily composite sample and so was unable to respond to possible peaks. Although being compliant with the effluent limits, the values observed fluctuate between 0.2 and 0.8 mg/L.
Hach LDO® technology improves the efficiency of pharmaceutical plant’s wastewater treatment process, helping to protect the environment and the community.
Levels of phosphorus, a chemical element that promotes organic growth, must be controlled in wastewater coming from beverage, food and dairy processing plants. Failure to control phosphorus accurately has a negative impact on water quality and can lead to large fines.
Compliance and consistent high quality are two of the key goals within the beverage industry. Hach® provides support for these goals through comprehensive analyses of water and beer.
There are several basic methods for reducing harmonic voltage and current distortion from nonlinear distribution loads such as adjustable frequency drives (AFDs). Following is a description of each method, along with each method’s advantages and disadvantages.
Organic carbon compounds vary greatly. In fact, one of the first lessons in most introductory Organic Chemistry courses explains that the number of possible carbon compounds is virtually infinite due to carbon’s ability to form long, chain-like molecules. While chromatographic methods like gas chromatography (GC) or high-performance liquid chromatography (HPLC) are able to make quantitative determinations for specific compounds, the user must first know which specific compounds to look for.
In the developed world, potable water is delivered to people via a complex infrastructure consisting of water catchment, water treatment, water storage (reservoirs, towers), and water distribution (pipes). The first two elements are well understood; what is less understood is what happens to water as it journeys to the tap.
What are some of the biggest global challenges, trends, and opportunities for the smart water sector in 2019? To answer these questions, the Smart Water Networks Forum (SWAN) interviewed four industry experts from Australia, North America, the UK, and India.
With time, labor, and money at a premium, state-of-the-art controls on filtration equipment can ease the burden on operators while improving uptime and lowering costs.
The big problem with Big Data has always been turning all that information into action. A recent survey reveals how far utilities have come and what might come next.
Did you ever have a paper route or go door-to-door selling items to your neighbors for a charitable cause in your younger years? Remember the house with the big dog? Or the overgrown yard? Maybe even the dark house at the end of the lane that the spooky old woman known to all as “the witch” lived in?
