Water and wastewater professionals rely on accurate flow measurements for process operation and regulatory compliance. Selecting the best flow meter for each application is essential to obtaining accurate flow data.
Because blowers are run continuously, energy costs associated with the aeration basin are typically the largest expense for wastewater facilities. The wastewater treatment plant in the city of Grand Rapids was looking to reduce aeration energy costs and recently upgraded the facility with a Hach Real-Time Control System. The result was a nearly $60,000 energy efficiency incentive payment from Consumers Energy, and the plant is now on track to save the city more than 735,000 kilowatt hours of electricity and $62,000 annually.
By making hypochlorite solution only as needed, the compact Constant Chlor unit brings efficiency, consistency to water reuse system.
Since 1977, Endress+Hauser has produced over two million electromagnetic flowmeters. That is more than any other manufacturer. “This magic number stands for high-quality measuring technology and, above all, satisfied customers in all kinds of industries,” says Bernd-Josef Schäfer, Managing Director of Endress+Hauser Flowtec AG, the center of competence for flow measuring technology.
The Jimo, China, municipal wastewater plant was originally designed to treat a combination of municipal and textile wastewater (120,000 m3/d) with Class IB effluent limits for BOD, COD, ESS, TN, NH3-N and TP.
Misinformation about WirelessHART networks prevails among many instrument engineers in the process industries. This article attempts to set the record straight by debunking seven myths about these networks.
A medical research company in the Midwest United States offers comprehensive services to help determine the safety of life-changing compounds and assist in bringing them to the marketplace as rapidly as possible. Their drug safety evaluation research services offer dedicated expertise in a wide variety of medical arenas.
Wastewater treatment plants use numerous pumps in a variety of types and sizes to move water through the process. Depending on plant configuration, they may pump influent, activated sludge, thickened or digested sludge, biosolids, scum, filtrate, effluent, or reuse water. Each matrix has specific characteristics that engineers consider when designing pumping systems.
Wastewater treatment can be a dirty job — but someone has to do it. At a Canadian wastewater treatment plant (WWTP) serving around 75,000 citizens, between 240 and 300 cubic meters of digested sludge are treated each and every day!
Maintaining the quality of wastewater (WW) effluent is more important than ever before, as municipalities deal with aging treatment systems, budget restrictions, and evolving compliance standards. As a result, water professionals need accurate and efficient tools to check water safety in the lab and in the field to determine levels of chemicals such as sodium, chloride, calcium, fluoride and ammonia, as well as pH, conductivity, and dissolved oxygen.

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.
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?
With more water and wastewater utilities, as well as industrial facilities, moving toward digitalization, it’s important to understand the needs of data gatekeepers and decision-makers to set them up for success.
Guided wave radar technology provides accurate and reliable level and interface measurement in effluent treatment areas, ensuring regulatory compliance and reducing costs in wastewater applications.
The 38th Annual Esri User Conference in San Diego was another great success, and an opportunity for us to showcase our integration technology. This year OSIsoft has received the Esri Partner Award for “Delivering in Real-Time”, marking a major milestone in our common journey to deliver real-time data inside Esri's maps. Award winners were chosen based on demonstrated best practices in their advanced use of Esri technology, and their contribution to taking the ArcGIS Platform's latest features and geographic visualization to the next level.
