For a pH sensor to maintain an accurate reading, the sensor must remain clean. Specifically, the glass measuring electrode cannot become coated, and the reference electrode assembly must not become coated, plugged or otherwise contaminated by the process solution. Here’s how to clean pH sensors to ensure correct operation.
In recent years, the debate about which technology is best suited for level monitoring and open channel monitoring (OCM) applications has taken some traction. There are those who argue that ultrasonic level technology has been uncontested as the standard for level and OCM applications in the water industry. The counter-argument is that radar technology is more effective because it is more robust and accurate than ultrasonic technology.
Users often question whether their measuring devices are working properly and within specified measurement accuracy. The new CoriolisMaster flowmeter models by ABB include technology for integrated online diagnosis and accuracy verification. This technology constantly monitors the oscillating meter tube within the flowmeter for erosion and coating deposits.
Achieving consistent water pressure is a challenge for geographical areas that have grown faster than the development of infrastructures to accommodate water demand and for businesses such as fast food restaurants and strip malls.
To ensure real-time monitoring of pump motor status at its five lift pumping stations, Sheboygan Regional Wastewater Treatment Facility, Sheboygan, WI, replaced its bi-metallic overload relays with Eaton’s Motor Insight™ overload and monitoring relays.
For decades, a Winnipeg utility used a multiple point-chlorination process to treat raw water drawn from remote Shoal Lake. Concerns eventually arose about the potential presence of chlorine-resistant pathogens–Crytosporidium and Giardia–and residual disinfection byproducts, which coincided with encroaching development near the lake. The Clari-DAF system was selected and now removes 70 percent of the organics at the Winnipeg plant, which also improves filtration and extends the intervals between filter backwashes.
Accurate measurement of water consumption across a large metropolitan area is no easy task, but for a water company it can mean the difference between profitability and throwing money down the drain. That’s why City West Water, a major water supplier to residential, commercial and industrial sites in and around the city of Melbourne, Australia, has been working with Siemens for more than a decade to install SITRANS F M MAG 8000 electromagnetic water meters at high-consumption sites and in fire service applications.
Call it what you want, but a busted pipe spells nothing but T-R-O-U-B-L-E.
A Municipal Water Plant in the Southeast United States treats and supplies potable water to a large metropolitan area. Part of the process requires accurate flow measurement of the water from individual pumps to the main distribution system. Part of the process requires accurate flow measurement of the water from individual pumps to the main distribution system.
When I look back at 2016 one of the most significant trends I observed was the growing acceptance of ORP measurements, especially for monitoring disinfection. With one caveat, the ORP value measured in a solution provides an unambiguous measure of the disinfection efficacy.
