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.
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.
Reducing water loss and saving money are two of the highest priorities—and most consistent challenges—facing water professionals. Both of these issues stem from water pressure control.
In today’s economic climate, it’s tempting to want to buy the cheapest test equipment you can now. But, how can you tell what the true cost of test equipment is? You have to consider how widely your water and chemical consumption will vary as the readings on your instrumentation does. By Heather Rekalske, Myron L Company
Oxidizing antimicrobials, such as chlorine, are common disinfectants used to treat water. Test strips, DPD kits, and colorimeters are currently the most popular methods for determining the relative disinfecting power of oxidizing antimicrobial agents in these applications. By Myron L Company
With the recent growth in demand and production of liquefied natural gas (LNG), there has been an increase in trade and the need to transport it globally via LNG tanker ships.
A municipal wastewater treatment plant investigated a sudden increase in fecal coliform exceedance events.
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.

The University purchases water from Illinois American Water which is distributed across the campus for uses as diverse as chemistry labs, agricultural research, and competitive swimming complexes.
Privatization of the United Kingdom’s (UK) water industry 25 years ago required providers to implement asset management programs (AMP) whereby water boards tendered contracts to construction firms to update the industry’s antiquated assets and help keep infrastructure properly maintained.
A large east coast water supplier faced a number of challenges with one of its pumping stations. It was built more than 35 years ago on a 25’ earth mound (“ant hill”) to protect it from flooding, the pumping station was becoming very expensive and inefficient to operate.
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.
The Series 71P11A Gas Pressure Reducing and Shutoff Valve is a diaphragm-type gas pressure regulating valve designed for use on chlorine, sulfur dioxide and ammonia gas service. The valve is used in a gas dispensing system to prevent liquefaction of the gas by providing a controlled pressure drop in the piping system. Downstream pressure is regulated to a reduced value by adjustment of the control setting. If the downstream pressure exceeds the pressure at which the valve is set, gas flow will be shut off.
