For more than 25 years, the Hach CL17 Colorimetric Chlorine Analyzer has been a well-established choice for continuous monitoring of free and total residual chlorine. Now, added connectivity, diagnostic, and maintenance features are making its trusted reliability and data accuracy more readily accessible and easier to manage than ever before. Here is how the experience of current users is being improved.
Managing three drinking water treatment facilities, multiple pump stations, more than 350 miles of pipelines, and a wastewater treatment facility is challenging even in normal conditions for a small city where agriculture is an economic driver and water demand can exceed 22 MGD.
A Digital Twin is a virtual replica of a physical asset that is updated in real-time via a two-way data connection and, as such, representative of its live characteristics.
A paint manufacturer produces a wide range of paint products for industrial, commercial, and residential applications. The products are manufactured in large batches of up to 10 tons. Before each batch is packaged and shipped, a number of tests are performed to ensure that the product meets strict quality control requirements.
A semiconductor manufacturing facility in France relies on an extensive cooling system to maintain stable conditions throughout their production facilities. The cooling system includes 19 cooling towers and 14 cooling water networks spread over a 135-acre site.
The main lift station serving the waste water treatment plant in Morgan’s Point, Texas, continually experienced problems with its three standard non-clog pumps. The pumps frequently clogged when rainfall totals reached or exceeded 2 inches. Shop rags, pieces of 2 x 4 lumber, plastic bottles, gloves, and wet wipes all commonly clogged the pumps when the standard demand increased. Pump removal, unplugging, and recurring repairs were required, but the service company was not always available for immediate assistance, causing problems for residents serviced by this lift station.
Denver Water serves 1.4 million people in the city of Denver and the surrounding suburbs. It is the largest — and oldest — water utility in the state of Colorado and its service area covers more than 335 square miles.
Water industry professionals are experiencing a data deluge. There’s a lot of data out there, gathered from sensors monitoring everything from water quality to pipe bursts — but altogether, it’s too much data divided among too many silos to make sense of what it all means.
Maintenance and performance of pressurized water distribution systems require a complete grasp on the pressure ratings of every component within the system. Mueller gives valuable insight here for pressure rating standards needed for flanged valves.
The need for a solid cybersecurity strategy has been discussed and debated for almost a half a century now, and yet the basic worm-type attacks first documented back in 1972 are still with us today. Why? Because even the most basic measures to protect control systems from these types of attacks are still not systematically employed.
The City of Rushville, Indiana had to remedy a consent order filed in 2007 for its untreated combined sewer overflow (CSO) discharges that were polluting the Flatrock River, a violation of the Clean Water Act. The city originally planned to install a 1 MGD stormwater storage tank, but was approached by Aqua-Aerobic representatives with a pilot test proposal utilizing a new technology.
Constant monitoring of critical motors while de-energized prevents failures on startup, reduces unscheduled downtime, saves on major rewinding repairs and increases personnel safety
Siemens offers to our customers the ability to both make process measurements and to remotely monitor the activity and health of that instrumentation without the need for SCADA systems or other expensive process control room products. By utilizing Siemens’ ability to offer unparalleled flow, level, pressure, temperature, and weight measurement as well as valve control, we can provide a broad range of process measurements and offer unequaled monitoring of the health and performance of those products.
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.
It took some time for computational fluid dynamics (CFD) to find its way to the water industry, but now that it has, a primer is warranted to understand its application.
The movie and sports term has infiltrated the business world and has important implications for the water/wastewater industry.
If you're not benefiting from the analytics readily available to your utility operation, you're missing out on efficiency and cost savings. For the curious and for skeptics, or if you want to advance your smart water journey, this Water Talk interview with Kevin Stively, Vice President and Smart Utility Services Leader at Brown and Caldwell, is a must-listen. Stively notes how the investment in smart technologies can be small — in comparison to the payback — and taken in "baby steps."
Installing flow meters in new piping is one thing. Replacing a 20-year-old meter or adding new metering to piping where it never existed before is quite another. In this Water Talk interview, Cheryl Ades Anspach, marketing manager with Badger Meter, offers a non-invasive alternative using easily retrofittable clamp-on ultrasonic meters offering accuracy to + 0.5 percent and flow rates to 33,000 gpm in pipes up to 48” diameter. Two palm-sized rail-mounted transducers provide simpler, more affordable installation than having to shut down or cut into a live pipeline or bring in heavy equipment to install a full-bore mag meter. Built-in datalogging backup (8 GB) with time-date stamp granularity down to one second provides ample opportunity for detailed flow analysis.
Everyone wants peak accuracy from their instrumentation, but nobody wants to disrupt their field process to verify it. Purvang Upadhyay, the global water industry manager for measurement and analytics with ABB, shared an attractive alternative to such disruption with the Water Talk moderators at WEFTEC 2019 — in-situ verification. This classic example of digitalization in the water industry enables users to check the health and accuracy of an electromagnetic flow meter against a digital ‘fingerprint’ of that meter’s performance the day it was originally calibrated or installed.
The water and wastewater industry has been dominated by automation based on programmable logic controllers working in tandem with SCADA. However, newer systems that better blend those aspects provide improved intelligence. As a result, plant operators aren’t required to maintain a separate engineering station to control strategy as well as the HMI.
