It seems that everywhere that you go in the water industry at the current time, somebody is talking about digital transformation…or if we go back five minutes, it was Water 4.0…and 10 minutes ago (it seems), it was “smart water.” These are all very well used buzzwords that the industry is destined to think about for a short-term and then promptly forget about. In reality, though, we as an industry have been hit by a number of different concepts for a number of different technological aspects for a good number of years now. For almost as long we have had a term for all of this — “widgets.”
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.
The movie and sports term has infiltrated the business world and has important implications for the water/wastewater industry.
Water utilities with highly successful monitoring programs tend to share a common trait: they have a well-defined plan for calibration that emphasizes frequency and tracking. However, when done properly, this process is time-consuming and often leads to unnecessary labor and downtime. The good news is that advanced metering technology is available for plants to get a better handle on the instrument’s performance with significantly less effort.
Digital devices provide two-way communication, so they can be programmed from the control room. However, the bigger benefit is that they can be part of a system offering assured interoperability to provide a seamless flow of information. This type of integration between key components of the water treatment and distribution process improves decision-making and overall equipment optimization.
When water and wastewater plant operators can’t get accurate flow measurements or analytical readings — or lack confidence in their instruments’ readings — it creates challenges with the process. When substandard water goes to homes and causes a boil order, or discharge pollutes a lake or reservoir, the resulting bad press, fines, and potential lawsuits erode public confidence. Avoiding these kinds of problems is rooted in good preventive maintenance habits.
Water and wastewater utility operators work diligently to operate within strict guidelines, ensuring their facilities are producing the best drinking water and highest quality effluent possible. Despite all their efforts, however, it can be easy to fall outside of regulatory compliance without even being aware. The key to avoiding problems like these is to understand how silent noncompliance can happen and knowing when to raise a red flag.
This paper presents the results of 12 V-Cone DP Flow meters tested over a period of 17 years. Service applications for the V-Cones included natural gas as well as coke oven gas measurement, a dirty aggressive fluid that is problematic over long period of time for most flow meters. All testing was conducted in air by a 3rd party calibration laboratory, CEESI Colorado. Results will be presented for each of the meters over the 17 year span. Conclusions and recommendations will be made to the long term performance and recalibration intervals for the V-Cone flow meter.
Water scarcity. Aging infrastructure. Uncertainty due to climate change. Experts from across the water sector agree that water challenges are intensifying, and that action and public awareness is a necessity. Now we have the need — and the opportunity — for those same voices to raise the volume on one of the most powerful ways to address increasing water threats: digital innovation.
In 2010, Shelby County Water Services (SCWS) was planning for the future. With new regulations on the horizon, SCWS determined that the Talladega/Shelby water treatment plant in Shelby County, AL, needed more effective removal of disinfection byproducts (DBPs). Specifically, the treatment plant needed help complying with the U.S. EPA’s new Stage 2 Disinfection Byproduct Rule (DBPR).
Fox Thermal Flow Meters use a constant temperature differential (constant Δ T) technology to measure mass flow rate of air and gases.
The Signet 2750 and 2760 pH/ORP Sensor Electronics and Preamplifiers, featuring connectors, provide a variety of functions to suit various requirements
Hach, the leader in water quality, has developed a customized solution for water quality testing that takes the guesswork out of your measurements.
Ideal Usage for Roll Off Box - Phase Separators: Separating and dewatering sludges, slurries and waste streams.
Purge and Trap Background
When using a concentrator system, it is not essential to understand how it works. However, a good grasp of the fundamentals helps you prevent problems and assists you when you are faced with tasks such as method development and troubleshooting. This section is not intended to be a full theoretical evaluation of purge and trap gas chromatography. The main purpose is to help you develop an understanding of how and why compounds are concentrated.
