As water and wastewater treatment plant (WTP/WWTP) processes and control systems become more sophisticated, maximizing operator effectiveness becomes more complex as well. A well-planned alarm and control strategy can make a significant difference between valuable decision-making information and confusing, disjointed, data points. This article highlights key strategies for foreseeing problems in advance, fixing them faster, and having a higher success rate by maximizing operator effectiveness.
A large percentage of the flow meters purchased for municipal water plants are replacements for older meters in existing facilities or distribution systems. It’s a common practice to replace aging meters with the same technology, often from the same manufacturer.
Wastewater treatment can be a dirty job — but someone has to do it. At a Canadian wastewater treatment plant (WWTP) serving around 75,000 citizens, between 240 and 300 cubic meters of digested sludge are treated each and every day!
Located just south of Montgomery, Alabama, the City of Troy is a unique mix of southern small-town charm and big-city amenities. Read the full case study to learn how the City leveraged Sensus’ Advanced Metering Infrastructure (AMI) solution to gather more data and monitor for issues likes leaks or pipe breaks
Water is a precious resource! Now, more than ever, businesses and facilities must take charge of their water usage to help with water conservation and lower water bills.
Due to their critical role in protecting the health of customers, drinking water treatment systems require a high degree of care and oversight.
Service. A large part of customer service is creating a seamless experience between the customer’s expectation, and your ability to exceed their anticipated need.
In 2008, the public utility manager in Ogden City, Utah sent out a request for proposal on a system-wide changeout of its meters, absolute encoders, and radio frequency meter interface units (RF MIUs), with a goal of eliminating estimating and replacing all their meters with AMR technology to read year-round. Read the full case study to learn more.
Evaporative cooling towers are key components in the effective operation of plants in the electric power, industrial process and manufacturing industries.
Yorkshire Water produces 1.3 billion liters of clean water and treats one billion liters of water in its waste water networks every single day. The company has 686 treatment facilities spread across northern England and 83,000 kilometers of water pipelines, which is enough to circle the earth twice.
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.
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.
Most of us don’t have to think about the vital infrastructure that supports our society. Water is delivered to our homes and businesses 24/7, and wastewater is efficiently and cleanly whisked away. The ability of our utilities to manage these services means we only take notice at times of inconvenience: water outages, sewer blockages, or stormwater overflows.
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.
