DRINKING WATER CASE STUDIES AND WHITE PAPERS

• Does Grinding Create Microplastics?

  Some industry professionals have concluded eliminating the use of grinders will prevent microplastics from entering the water cycle. This thinking is wrong for a range of reasons.

• Long-Term Performance And Boron Rejection Of LG SWRO Membranes In Malta Desalination Plants

  Malta is an archipelago of three islands situated in the Mediterranean Sea, around fifty miles south of Sicily. There are no rivers of any significance on the islands, and the sparse annual rainfall is only about 500 mm. In order to bridge the gap between supply and demand, Malta has long ago started desalination of seawater. The technologies were initially based on evaporation. In 1981 the Government decided to invest in RO desalination capacity.

• City Upgrades AMI System For Boost

  The city of Yakima was in search of a vendor who could provide a turnkey solution with a quality product line. The selected vendor also needed to have an endpoint that could withstand the extreme conditions experienced inside their meter pits.

• Disinfection Performance Testing Of High-Efficiency Ultraviolet Water Treatment Chamber

  This is the second in a series of three white papers describing the design and performance of the NeoTech Aqua ReFlex™ treatment chamber. The first describes in detail the theoretical basis for the very high efficiency demonstrated by the chamber. The third paper describes how this chamber design leads to some highly desirable operational advantages beyond just energy ad cost reduction. By J. R. Cooper, Ph. D. and Gwynne Cavender, NeoTech Aqua Solutions, Inc.

• A Better Way: An Application For Risk Characterization of HABs On The Ohio River

  When you think of water, you might imagine deep blue ocean waves crashing against a shoreline or perhaps the still calm of a forested lake, but on an August morning in the summer of 2015, the lockmaster at the Pike Island Lock and Dam saw something much different. That day, EPA’s regional office in Wheeling, WV, received a concerned phone call from the Ohio River Valley Water Sanitation Commission (ORSANCO) notifying them of what was described as “antifreeze-green colored paint” flowing down the Ohio River. But this was no paint spill. Rather, Microcystis, a naturally occurring species of cyanobacteria, or blue-green algae, known to produce toxins harmful to animals and humans, was quickly taking over one of the most influential rivers in the continental U.S.

• Pilot Test For Arsenic, Color And Iron Shows Great Results (Loprest)

  The City of Riverdale was running into issues with arsenic, color and iron treatment system at their Well 4 site, so they conducted a pilot test with the help of Loprest.

• The Enduring Value Of Ultrasonic Level Measurement In Water And Wastewater Level Applications

  Discover how using ultrasonic technology allows level and pump controllers to progress in ways that enhance both accuracy and usability — rather than remaining static.

• Global Omnium: Transforming From Conventional To Smart Water

  Lessons learned from building one of the largest smart meter networks in Europe.

• AMERICAN Flow Control's Semper™ RPM With “Lift And Shift” Capability Helps Lowcountry Regional Water Resolve System Pressure Issues

  In the summer of 2020, the Lowcountry Regional Water System in Hampton, South Carolina, had a customer located in an industrial park report a low water pressure issue. The company was a commercial laundry that served the hospitality industry and provided linens to hotels around the Hilton Head area. The low water pressure issue was causing the company’s heat recovery system to work improperly shortly before the July 4 holiday. In its first use of the AMERICAN Flow Control SEMPER™ Remote Pressure Monitor (RPM), Lowcountry Regional Water System deployed two units to resolve the issue. One device was located on the water system’s side of the meter and the other device was placed inside the company’s building, where water enters the facility at the backflow preventer.

• A Lesson In DMA Management

  White House Utility District (WHUD) is one of the largest water and sewer utilities in the state of Tennessee. While developing a network of pipelines, pumping stations and storage units was challenging, the greater test came in finding access to a plentiful water supply.
