For municipal water systems, the endless demand to maintain water quality can be challenging. Anytime the quality or pressure drops far enough to necessitate a boil notice, the costs to inform residents and get the problem under control can be extensive. It can also create a public relations nightmare. Newer solutions provide a cost-effective way to build an entire smart utility network to more proactively manage water quality and generate greater ROI.
Contact ultrasonic level switch technology was first applied to process control in the 1960s – and continues to provide accurate and reliable liquid level measurement in virtually every process industry today.
“You can’t manage what you don’t monitor”, an adage first attributed to Lord Kelvin applies to practically everything including water distribution systems.
MidCoast Water delivers water and sewerage services to 40,000 households in the Manning, Great Lakes, and Gloucester communities of New South Wales in Australia. It also supplies 8 billion liters of water a year to Karuah in the south, Crowdy Head in the north, and Gloucester in the west.
Water and wastewater leaders are unsung heroes. Clean, safe water is essential to human life and to the well-being of the environment, yet it is grossly underfunded. Limited resources lead to deferred maintenance and difficult decisions.
NSISP is one of South Australian Water Corporation’s (SA Water) biggest infrastructure projects undertaken in Adelaide metropolitan to connect the north and south drinking water distribution systems and to increase access to their desalination plant. The project included the construction of 32 km of pipeline through metropolitan main roads and suburban inner streets. This is no small feat and getting it done right meant fitting together a lot of different moving pieces.
When selecting a new analyzer for your plant, there are many different features to consider. One of those is the choice of how the instrument will be calibrated, namely between an inexpensive manual calibration and a more complex automatic calibration method. (To be clear, we will define automatic calibration as a feature that involves no operator intervention at the instrument.) Factors that influence this choice are financial, process, staff levels, and personal preference. Let’s explore each of those.
When Northshore Utility District began searching for a new meter reading solution in 2006, achieving a strong return on investment was a critical factor in its selection process.
You want good pH data. Who doesn’t? You deserve good data, but for good pH data you need to calibrate. You need to calibrate well and calibrate often. By Lyndsey McDermand
Control of dissolved organics has been one of the highest priority concerns for most water treatment plants for over 20 years. Organics monitoring is an even more critical issue today in the face of more stringent regulations and concerns around trace organics, emerging contaminants, and even counter-terrorism or water security. Despite the critical need, many plants still rely primarily on turbidity for monitoring and process control.
SUEZ Water Technologies & Solutions designs and manufactures Sievers Total Organic Carbon (TOC) Analyzers that enable near real-time reporting of organic carbon levels for treatment optimization, quality control & regulatory compliance. TOC has a wide range of applicability at a drinking water plant, and therefore any drinking water utility — large or small — can measure TOC in their laboratory or online in their treatment process.
As the world’s population continues to increase at a fast pace, more food and water will be needed to sustain humanity. In the past 50 years, we have tripled our need for water and food, and there are no signs of this trend slowing down. As a result of these conditions, smart, innovative agricultural practices are needed now more than ever. Technology can, and already does, aid agriculture in innumerable ways. One prominent part of agriculture that can use technological innovation to increase efficiency and effectiveness is irrigation.
Water in petrochemical feedstocks can cause problems for processors. Freezing of pipe lines and valves and poisoning of expensive catalysts are just a few examples.
The analysis of water for volatile organic compounds is important due to their toxicity. The current methods for this determination lack of sensitivity, selectivity or capability for automation. This paper presents the new ISO 17943 Standard using Solid Phase Microextraction (SPME) and GC/MS. The sample preparation by SPME enables limits of detection and easy automation of the whole method. GC/MS provides the required sensitivity and selectivity. This ISO Standard was validated by an interlaboratory trial, which results confirm the outstanding performance for this method.
In this paper the importance of reagent water quality for toxic element environmental analyses is discussed, and the suitability of fresh ultrapure water produced using MilliporeSigma water purification systems for ICP-OES and ICP-MS trace element analyses in environmental laboratories is demonstrated.
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.
The water municipality at a mid-size city in the Western region of the U.S. serving a population of about 180,000 people needed to address a chlorine disinfection system problem at one of its water treatment plants.
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.
The task of managing the quantity and quality of potable water is unimaginable without online instrumentation to help water utilities to measure, treat and deliver drinking water to consumers. ABB’s Aztec 600 colorimetric and ion-selective electrode (ISE) analyzers have been designed to measure the key parameters that affect water quality – aluminium, iron, manganese, phosphate, color, ammonia and fluoride.
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.
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.
