In the agriculture sector today, where water usage reporting is increasingly becoming a requirement for irrigation system operators that divert water in regulated areas from ground and surface sources, accurate metering is critical.
Water and wastewater treatment professionals are constantly looking for as much information as possible about the quality of their water. If knowledge is power, then understanding the properties of their water is key to running an effective and efficient facility.
Water management professionals know all too well that problems arise — usually sometime after 2 a.m., or just as you’re walking out the door for a holiday weekend. No matter how well-prepared you are, or how sophisticated your system, sometimes you’re going to run into challenges. It’s simply the nature of the industry. When you experience an issue with your valves (especially when they’re failing to open or close as expected) your first instinct is to call the factory for support. While some cases may require factory assistance, this isn’t always the most efficient solution.
Evaporative cooling towers are key components in the effective operation of plants in the electric power, industrial process and manufacturing industries.
When municipalities choose to manually feed phosphates into their potable water, this often creates an over-feed of chemicals. Learn how employing an automatic-dosing phosphate analyzer can reduce operating costs and improve reliability.
To ensure real-time monitoring of pump motor status at its five lift pumping stations, Sheboygan Regional Wastewater Treatment Facility, Sheboygan, WI, replaced its bi-metallic overload relays with Eaton’s Motor Insight™ overload and monitoring relays.
Satisfying water purification and volume requirements at the treatment plant or wellhead are not the only cost-performance impacts on physical operations. There are other variables related to distribution operations that affect head loss and energy costs throughout a distribution system. Here are several strategies for identifying, calculating, and minimizing head loss.
Lead in drinking water has become a very visible issue of considerable concern over the last few months. While municipalities across America have been scrutinizing the quality of their drinking water, it should at least be some consolation that manufacturers of measurement instrumentation have taken serious steps to assure that they are not contributing to the problems that have been encountered.
As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas.

You want good pH data. Who doesn’t? You deserve good data, but for good pH data you need to calibrate. You need to calibrate well and calibrate often. By Lyndsey McDermand
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.
The water municipality at a mid-size city in the Western region of the U.S. serving a population of about 180,000 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.
The task of managing the quantity and quality of potable water is unimaginable without online instrumentation to help water utilities to measure, treat and deliver drinking water to consumers. ABB’s Aztec 600 colorimetric and ion-selective electrode (ISE) analyzers have been designed to measure the key parameters that affect water quality – aluminium, iron, manganese, phosphate, color, ammonia and fluoride.
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.
The landscape is changing for water consumers and suppliers and the delivery systems that connect them, with data and analytics forging the path ahead.
In the small community of Llimbe in Peru, water sources were running dry. The population had grown from 35 to 50 families, and some of the families were using more water than they actually needed. Because of this, if you lived higher on the hillside, you may only have water for an hour a day.
Research scientists are making strides to advance the safety and application of potable water reuse through the use of metagenomics for water quality analysis.
Is water hammer pounding your pipeline infrastructure into submission? Here are some tips for avoiding issues associated with hydraulic transients.
The U.S. is currently facing a water crisis. Potable water is scarce and considered valuable everywhere in the world. However, with the infrastructure that is currently in place, the U.S. has been squandering this precious resource. According to the American Society of Civil Engineers, about 6 billion gallons of treated water are lost every day due to broken and leaky pipes alone.
