Water hardness can wreak havoc on your boilers, creating holes in tubes, eating away at the walls. To keep the hardness at bay, you’re going to need to monitor the levels of calcium and magnesium seeping into your system. There are things you need to know to ensure that you are doing this properly. First, use an automated system to increase reaction time to hardness. Next, monitor the softeners; they are critical in keeping the system functioning. Last, learn the temperament of your individual boiler; no two are alike.
Industrial pumps consume up to 20% of the world’s energy production and can be responsible for 25 to 50% of a process plant’s energy bill, according to Europump, the Hydraulic Institute and other sources. Nothing moves without them in a process plant, and they are expensive to purchase, maintain and even more to repair or replace. Reducing pump lifecycle costs (their purchase, operation and maintenance) is critical in a process plant optimizing efficiency and product output. The process and the surrounding equipment configuration can be responsible for unnecessary high pump lifecycle costs.
Reducing water loss and saving money are two of the highest priorities—and most consistent challenges—facing water professionals. Both of these issues stem from water pressure control.
Many water quality plants are using flow controls to help achieve critical operational goals. This recent case study shows how thermal dispersion flow meters can help your plant ensure compliance with stringent government regulations.
Monitoring chlorine and fluoride levels in the drinking water of Utah’s Taylorsville-Bennion Improvement District used to be expensive, labor intensive, and often sensitive to interference from the variable frequency drives used to operate the chlorine injection pumps. That is, until the district upgraded to Rosemount free chlorine and fluoride sensors and analyzers from Emerson.
GF Piping Systems technology and its unique approach to business are an integral part of Akron’s plant improvement plans.
Responsibility for analysis results lies with the users themselves or their supervisors. Both are therefore liable for any incorrect interpretations and decisions that are made as a consequence of incorrect data.
In today’s economic climate, it’s tempting to want to buy the cheapest test equipment you can now. But, how can you tell what the true cost of test equipment is? You have to consider how widely your water and chemical consumption will vary as the readings on your instrumentation does. By Heather Rekalske, Myron L Company
In recent years, the debate about which technology is best suited for level monitoring and open channel monitoring (OCM) applications has taken some traction. There are those who argue that ultrasonic level technology has been uncontested as the standard for level and OCM applications in the water industry. The counter-argument is that radar technology is more effective because it is more robust and accurate than ultrasonic technology.
Fox Thermal Flow Meters use a constant temperature differential (constant Δ T) technology to measure mass flow rate of air and gases.
Being able to accurately measure both the quantity and rate of water passing through a water distribution system is crucial to gaining an informed understanding of overall efficiency. As such, achieving a measurement that is exact as possible can have a significant impact on key areas including supply planning, maintenance and resource deployment, leakage detection and rectification and the overall environment, in terms of controlling abstraction and reducing unnecessary draw on natural resources.
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.
Disinfection is a very important part of the drinking water treatment process, and choosing between an amperometric and colorimetric chlorine analyser is a decision that depends on a variety of factors. Below you will find out why a colorimetric analyser was the right choice for our customer, given their specific situation.
"The variable concentration of solids when purging lamella clarifiers creates problems with sludge dewatering. These problems are exacerbated when changing the flocculant. Read the full application note to learn how automatic control of purge cycles for clarifiers using the Sonatax sludge level probe resulted in reduced energy consumption and maintenance at the plant."
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.
Determining trihalomethane levels using standard analytical methods requires expensive equipment and highly qualified personnel, which also means that analysis costs are very high. For these reasons, trihalomethane analysis poses a serious problem for companies that supply drinking water. Read the full application note to learn how two drinking water laboratories improved quality control of water delivered to end users.
In 2013 the Drinking Water Inspectorate for England & Wales announced that water samples collected in England and Wales must be tested in a laboratory that meets specific standards for drinking water sampling and analysis. At the time of the new instruction, the chlorine method employed at the Welsh Water Bretton laboratory was unable to meet these requirements, notably for the prescribed limit of detection. This prompted the laboratory to investigate new analytical options for monitoring residual chlorine.
In the early days of variable frequency drive (VFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars, and aluminum foil.
The C445 motor management relay offers the most configurable protection options in the industry, with features specifically designed to protect critical pumps from costly damages due to dead-head and other underloaded or starved pump conditions.
Advancements in submetering and cloud-based data analytics help reduce consumption, lower costs, and improve operational efficiency.
The utility of the future will become an integral part of “smart cities.” These forward-thinking cities and utilities will have a complete sense of operations and millions of points of data streaming in at all times, allowing them to operate more efficiently and effectively. One component of the advanced water utility is already in the hands of many: smart meters.
A research project is vetting streamlined analysis for detecting NDMA in water. It could save laboratories time and money, and maybe even change the way they test for all trace contaminants.
Kansas City’s Smart Sewer program represents the nation’s first federal consent decree to include green infrastructure solutions in the reduction of wastewater overflows, as well as the city’s largest infrastructure investment to date. Projects that include the words “first” and “largest” do not come along without the strong leadership of a “Water Champion” such as Special Assistant City Manager Andy Shively, PE, who shares his experience and expertise in this Q&A.
Water utilities are tasked with ensuring a sustainable and safe supply in addition to achieving business and service excellence goals. These goals are typically based on criteria that measure operational performance, meeting bond covenants, and customer satisfaction.
