When selecting a new analyzer for your plant, there are many different features to consider. One of those is the choice of how the instrument will be calibrated, namely between an inexpensive manual calibration and a more complex automatic calibration method. (To be clear, we will define automatic calibration as a feature that involves no operator intervention at the instrument.) Factors that influence this choice are financial, process, staff levels, and personal preference. Let’s explore each of those.
Ocean Isle Beach is a small island community on the southeast coast of North Carolina. Only about five-hundred people live there year round, but during the summer months its beautiful beaches draw almost ten times that number. This poses unique challenges for the town's wastewater utility who must handle this extreme seasonal spike in usage.
In February of 2014, due to severe drought conditions, the Federal Bureau of Reclamation informed central California farmers that they would receive no irrigation water from the lakes, canals and reservoirs under the Bureau’s control.
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.
Filtration OEMs can use built-in device diagnostics to monitor and maintain automation component performance.
The CNSolution 9310 analyzer is used in precious metal processing to measure and control cyanide used in the hydrometallurgical leaching of gold and silver from the ore.
A municipal wastewater treatment facility located in Louisiana was having problems with a clamp-on ultrasonic flowmeter that was supplied by a Siemens competitor.
Water is a precious resource! Now, more than ever, businesses and facilities must take charge of their water usage to help with water conservation and lower water bills.
Wonderware InTouch has been the world’s number one Human Machine Interface (HMI) for over 25 years and offers legendary ease of use, market leading innovation, unequalled investment protection, brilliant graphics, unsurpassed connectivity, the industry’s best support and the broadest partner ecosystem.
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.
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.
Water quality test strips have been around for decades. They are usually constructed from a porous media, including different types of paper, and undergo a color change when dipped into water containing the analyte of interest. These test strips have seen application in swimming pools, aquariums, hot tubs, remediation sites, and other commercial/environmental areas.
Steinbach is the third largest city in Manitoba and one of the fastest growing census agglomeration areas in Canada with a population of about 50,000 people. Though Steinbach is primarily an agricultural community, it is also the regional economic hub of southeastern Manitoba. Due to the age of the wastewater control system, the city decided it was time for some new technology. This profile will describe the process of that upgrade and why they chose VTScada.
Clay County, located in Northern Florida, has a population of almost 200,000. In April 2016, Clay County Utility Authority (CCUA) needed a new SCADA system to monitor seven reclaimed water sites that the Authority uses to determine water storage times, using this data to route water from site to site. VTScada was selected by CCUA and their engineer.
As interest in biogas grows, more attention is being paid to measuring biogas flow, which has long been a problem area in process measuring technology.
The clarity of water in a stream, river or ocean is a key determinant in fostering a healthy and balanced aquatic ecosystem. The clearer the water, the greater the ability of light to penetrate to aquatic plants which generate the oxygen needed for aquatic life.
If you feel like you have too much data but not enough understandable or usable information, fine-tuning data collection and funneling it into an integrated data management system may be the way to become more proactive and make better decisions.
To minimize losses and address mounting concerns, the water industry is now adopting advanced sensor and communications solutions designed specifically for “smart” Internet of Things (IoT) water management. In large part, the move toward implementing smart water solutions is being driven by stricter government compliance requirements, the evolution of smart cities, and the need for water conservation.
Many industries use laboratory analyses to help with process control and regulatory compliance. However, process operators often need real-time results to make adjustments. Mobile testing methods are critical for troubleshooting problems and optimizing performance.
Satellites provide the latest, perhaps most efficient, method for spotting underground leaks, ushering in a new era of non-revenue water management.
