Wastewater treatment facilities use multiple processes and a variety of equipment to produce water clean enough for reuse. Each process within the treatment train may serve a different function yet use the same or similar equipment. In such cases, standardizing equipment may be beneficial.
Evaporative cooling towers are key components in the effective operation of plants in the electric power, industrial process and manufacturing industries.
Last year when a R&D chemical manufacturer needed help with their largest capital project to date; the Greenfield plant construction project, they turned to Texas Industrial Control and Manufacturing (TICM) who provided the electrical design support and control panels for the project along with Arrington Automation to architect the control system, lead the control system design process, and implement the controls solution.
In addition to managing operational efficiency and customer usage, utilities are driven by demanding regulations for improved quality, safety, and security. For remote monitoring applications, data acquisition systems (DAS) can provide an enhanced understanding of network operations through detailed documentation. This white paper presents the advantages of remote DAS over SCADA, including the ability to measure data even when communication channels fail or computers crash. By Barry Ceci
Serving a suburb of the Greater Austin Metropolitan Area, Dripping Springs Water Supply Corporation (DSWSC) recently decided to replace their Wonderware and WIN-911 system with VTScada, with the help of Austin area integrator, Central Texas Water Maintenance (CTWM).
Whether it is dining out less often or putting off that new car purchase just a bit longer, it seems that doing more with less is something many of us have become accustomed to over the last few years. Consumers are not the only ones feeling the pinch. By Doug Johnson, Emerson Process Management Power & Water Solutions
Flow measurement instrumentation options abound, and the challenge of picking the right one for a particular application can be daunting.
Measuring DO in the CBOD procedure was once troublesome and inefficient for lab personnel and operators alike at the Southside Wastewater Treatment Plant in Tyler, Texas. But all that changed when they adopted new luminescent technology that has eliminated problems with instrument drift, slow measurements, and frequent maintenance.
Business process management (BPM) has proven extremely successful in managing both gradual and radical improvements in the industry and various business functions. While digitization brings incredible new opportunities, it also brings the distinctive challenge of correctly positioning and scoping BPM in organizations.
While point level measuring approaches are regarded as simple and user friendly, they lack the capabilities of more sophisticated continuous measuring instruments.
At a water treatment plant that provides drinking water for distribution to a large area of customers, a contractor decided to switch to SITRANS FM MAG 5100W flowmeters. A local representative saved a the contractor time and money by recognizing the need for the magmeter to be isolated from the piping protection before startup, which also saved the customer from added downtime.
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 digital revolution has reached our utilities, but not everyone is taking advantage of how it can, for example, make water and wastewater cleaner, healthier, and more efficient. National news media seemingly report daily on U.S. infrastructure, but they rarely get down in the trenches with the public works professionals who are accomplishing so much. Three of them, who are using the Internet of Things (IoT) to better manage critical assets, tell their stories here.
There is little doubt that America’s infrastructure is aging, and in some cases, operating well beyond its originally intended lifespan. With labor costs representing up to half of the cost of pipe replacement, the key to cost-effective water and wastewater utility strategies revolves as much around labor-saving installation efficiency as it does around the physical performance of a particular material. Here is a look at historic failure rates, causes, and factors to consider when replacing existing water distribution and sewer networks.
Q&A With Opworks™ User And Developers
I became interested in water and the Internet of Things (IoT) several years ago when I had a below groundwater leak at home that resulted in a large water bill. Since I live in the Silicon Valley, CA, the high tech capital of the world, I thought there should be a better way to track water usage so problems can be identified and solved sooner.
Research studies, empirical evidence, and the march of time all suggest that the implementation of next-generation technologies at wastewater utilities is profoundly important, if not imperative, for efficient operations.
