DRINKING WATER CASE STUDIES AND WHITE PAPERS

• ABB Flowmeters Help Cut Water Loss In Bangkok

  ABB’s AquaMaster flowmeters have been integral to the overall water management solution. Over 400 AquaMaster flowmeters actively serve the Bangkok Metropolitan area helping optimize the management of the water distribution network. 

• Desalination In The Caribbean

  More than 7,000 islands of the Caribbean Archipelago are scattered over a million-square-mile area between North and South America. Some smaller islands are naturally dry, but some volcanic islands — like Grenada and St. Lucia — are well forested and provide significant water catchment to support spring water and surface water. But, as populations, agriculture, and industry grow, desalination is becoming more attractive as a water source throughout the entire region.

• Alternatives To Pump Alternation Schemes Using Advanced Level Controllers

  This article will focus on the pump control functionality of advanced level controllers and how they can help to optimize your process.

• Water For A Healthy World

  We are pleased to present Xylem’s ninth annual Sustainability Report, which describes our efforts in 2019 to solve global water challenges and support a healthy world. The How We Think About Sustainability section of this report explains the connection between current and emerging issues of water scarcity, water systems resilience to climate change and other water challenges and water affordability, and Xylem’s pivotal role in addressing these issues. We close out our goals set in 2014 and share our initial progress report against our 2025 goals, which we introduced in 2019, including Signature Goals designed to tackle some of the world’s most pressing water issues.

• Filtration Of Invasive Zebra Mussels From Lake Michigan

  Due to new construction and foot print limitations for the Milwaukee Art Museum, a new chiller feed line was fed directly from Lake Michigan and a filtration system was needed to prevent zebra mussels from entering the feed line and clogging the system.

• Tennessee Town Checks For Water Loss In More Than 8,000 Feet Of Pipe

  Learn how Electro Scan helped a rural Tennessee town check for water loss and to find the sources of its non-revenue water (NRW). 

• Direct Burial Meters Offer Significant Savings

  Most pipelines are below grade, so vaults have traditionally been installed to provide access to any place where a meter and valve are necessary. Vault pits tend to be large, and the installation is by far the biggest expense of a metering project. The good news is that direct burial metering options can greatly simplify the installation requirements, significantly lowering the costs, while also boosting safety.

• The Chemistry Of A Bloom: What Water Tests Reveal About Toxic Algae

  Understanding the chemistry behind algal blooms is key to early detection, effective monitoring, and mitigating their impacts. Fortunately, water testing technologies are revealing powerful insights into what’s really happening below the surface. 

• On The Job In 72 Hours Following Utility's Massive Water Main Break

  On the morning of December 12, 2017, about 30 homes in the Shelby Park neighborhood of Lousiville, KY, were without water, and others were experiencing low water pressure after a massive water main break at the intersection of Clay and Oak streets. More than 20 million gallons of water flooded the neighborhood, covering a three-block area.

• An Alternative Mathematical Model For Oxygen Transfer Evaluation In Clean Water

  Energy consumption from aeration system is a biggest part of the total energy cost in wastewater treatment plant and account for as much as 60% of the energy consumption for the activated sludge process. Therefore, it is very important to know how effective the aeration system and significant attention has been paid to development and upgrade of standard method for quantifying oxygen transfer efficiency of the aeration system.
