Nearly every industry requires water and wastewater treatment to some degree. From food and beverage to pulp and paper operations, influent and effluent must meet certain conditions to adhere to regulatory and/or performance requirements, and water used during the process must conform as well.

One of the world’s largest manufacturing plants improves efficiency by adopting a unified HMI to monitor water/wastewater, compressed air & liquids, and lighting. By Christopher Little
Water treatment plant (WTP) and wastewater treatment plant (WWTP) operators are increasingly supporting better decision-making by leveraging digitalization capabilities available through instrumentation and plant management systems. Successful adoption of digitalization starts with identifying the right balance of tools (i.e., web-networked instrumentation) and systems (i.e., analytical data management software). Maximizing the value, however, is as much about exercising a mind-set of efficiency as it is about tracking raw numbers.
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).
KROHNE has successfully deployed its TIDALFLUX electromagnetic flowmeter solution for many applications throughout North America to provide crucial process information. This document high-lights the results of two such projects.
Water hammer is a very common term in the world of water. Not only can this phenomenon happen in water treatment plants but also just about any pumping system and even steam systems.
Distributed control systems (DCSs) and programmable logic controllers (PLCs) are not mutually exclusive technologies. When the end-use application serves as the basis for making a sound decision, the selection process becomes more efficient, and a more effective outcome results. This white paper provides general guidelines and highlights key considerations when choosing a control system platform. While the details of each application are critical to the selection process, use the following as a guide when designing, specifying, and implementing controller technology.

Continuous analyzers are an integral part of the process to maintain quality, ensure compliance, and protect public health. Therefore it is imperative to ensure the analyzers are functioning properly and provide accurate and reliable data. This requires validation of the data provided by the analyzer on a routine basis. In addition some continuous analyzers incorporate internal data validation capabilities to inform the end user the reliability of the data provided by the analyzer. This paper discusses integrated data validation and how they may be integrated into SCADA systems.
In response to the devastation from a 2013 typhoon that caused the Yongxin and Yongjiang rivers in Ningbo, China to overflow, Ningbo Raw Water Group Ltd. commissioned the detailed design and construction of a CNY 178 million emergency sluice pump. The pump would provide flood control measures and mitigate future flood losses to improve urban infrastructure services within the Zhejiang province. To avoid the risk of additional flooding from another typhoon, the Raw Water Group required the urban flood control project to be delivered in a demanding eight-month schedule—a process that would ordinarily take 24 months to complete.
Proper measurement of pH is a key factor of corrosion risk surveillance in water-steam cycles.
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.
It has long been established that predictive maintenance of existing equipment will reduce operating costs and help ensure safe operation.
With data comes decision-making power, but how each utility wields that power will be different. The Smart Utility approach tailors digital capabilities to arrive at specific and optimal outcomes.
With a little help from AI (artificial intelligence) and IoT (the Internet of Things), Kansas City gives a lesson on UEA-MEP — utilizing existing assets to the maximum extent possible.
A survey of water utilities conducted by Black & Veatch reveals to what degree and how rapidly (or not) data analytics are being implemented in the real world.
While it may be premature to claim wastewater management’s arrival in the digital age, we can herald the eventuality, chart the progress, and examine potential implications.
