All the effort and expense required to produce high-quality water can be for naught if the distribution system cannot maintain appropriate pressure to deliver it efficiently, at a reliable flow rate. Simply pumping more pressure into the system is not the answer. Learn how new pressure monitoring options make it easier to track pressure in every zone to deliver customer satisfaction at peak energy efficiency.
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.
A company with multiple natural gas liquid (NGL) fractionation process facilities located in the Southeastern U.S became concerned about a series of missed events and nuisance alarms caused by the flow switches installed to monitor potential overpressure situations with its pressure relief valves. The company wanted a highly reliable flow instrument solution that would detect a real event and avoid the lost productivity of nuisance alarms.
Drinking water utilities have a lot on their plates. Aside from the inherent technical difficulty of providing a vital service, they have to maintain positive customer relations, contend with increasingly strained budgets, and run operations with as little stress to employees as possible.
There is little doubt about the importance of taking turbidity readings as part of drinking water treatment. However, there are certain misperceptions about the associated requirements and procedures needed to confirm the validity of those readings. The major points of confusion seem to revolve around perception of the terms “approved,” “calibration,” and “validation.” Here is a quick synopsis on what you really need to know about meeting U.S. EPA Method 180.1: Determination of Turbidity by Nephelometry for accurate turbidity readings.
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.
One of the most commonly used measurements in the water and wastewater industry is pH. A measurement of how acid or alkaline a substance is, a pH reading can instantaneously indicate a problem with the water. Another common and useful measurement is oxidation-reduction potential (ORP). Treatment facilities use ORP sensors to optimize disinfection and biological nutrient removal processes.
In drinking water treatment’s ongoing battle between disinfection and disinfection byproducts (DBPs), most water utility customers are oblivious to the process. One thing they do notice, however, is when their water smells or tastes bad. Here are some insights that can help water treatment plant (WTP) operators deal with their internal concerns about DBPs and residual chlorine or ammonia levels, as well as their external concerns about customer perceptions of water quality.
A U.S. company develops energy technologies that are environmentally sustainable and provides their customers with the ability to use their energy sources in a more practical and cost-effective manner.
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.
Fox Thermal Flow Meters use a constant temperature differential (constant Δ T) technology to measure mass flow rate of air and gases.
Being able to accurately measure both the quantity and rate of water passing through a water distribution system is crucial to gaining an informed understanding of overall efficiency. As such, achieving a measurement that is exact as possible can have a significant impact on key areas including supply planning, maintenance and resource deployment, leakage detection and rectification and the overall environment, in terms of controlling abstraction and reducing unnecessary draw on natural resources.
What are some of the biggest global challenges, trends, and opportunities for the smart water sector in 2019? To answer these questions, the Smart Water Networks Forum (SWAN) interviewed four industry experts from Australia, North America, the UK, and India.
There are many options for ensuring accurate billing of water used at established industrial customer locations. But how do municipalities or businesses keep track of water availability and use for intermittent applications or movable access points? We spoke with McCrometer, Inc.’s Marc Bennett for insight into how water utilities and industries can efficiently track and allocate water use for billing or internal accounting purposes in such ad hoc applications.
When it comes to fixing pipeline infrastructure, the pressure is on — but is it being measured? Intelligent pipe solutions provide flow and pressure data for improved service and water quality.
The 38th Annual Esri User Conference in San Diego was another great success, and an opportunity for us to showcase our integration technology. This year OSIsoft has received the Esri Partner Award for “Delivering in Real-Time”, marking a major milestone in our common journey to deliver real-time data inside Esri's maps. Award winners were chosen based on demonstrated best practices in their advanced use of Esri technology, and their contribution to taking the ArcGIS Platform's latest features and geographic visualization to the next level.
The water burbling down the rural hillside, nurturing the thick foliage, certainly looked like a stream.
