DRINKING WATER CASE STUDIES AND WHITE PAPERS

• Jar Testing Gets An Upgrade

  Jar testing is a common laboratory procedure used at water and wastewater treatment plants. In a set of beakers a defined amount of water is mixed with varying amounts of coagulant, and through observation by a trained operator the optimal amount of coagulant can be determined.

• Top 10 Customer Touchpoints

  Cities must gain the buy-in and support from the public and elected officials to secure necessary funding for smart water tech. Optimizing the initial costs of deploying smart water tech are going to vary, mainly depending on the size of the utility. Buy-in and support will only occur when utilities effectively make people understand, what’s in it for the customer. Water utilities need to communicate the value of AMI through the lens of what matters most to the end user—your customer, the consumer of your product, the ratepayer.

• 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.

• Water Authority Chooses Siemens Pressure Transmitters For Accuracy, Reliability And Ease Of Use

  A county water authority in the Northeast U.S. supplies over 40 million gallons per day to its 340,000 residential customers. In this case study, learn why they chose Siemens pressure transmitters. 

• How To Take Charge of Your Water Quality Analysis For Chlorine Disinfection

  The use of chlorine to treat and disinfect drinking water and wastewater has been in practice for decades, with the earliest recorded attempt dating all the way back to 1893. Since then, it has come a long way.

• 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.

• Pumping And Performance Analytics: A Penny Saved Is A Penny Earned

  Pump performance analytics are just as important as having properly maintained pumps for saving money through optimized treatment plant and distribution system operations. Discover how one utility is using real-time analytics to manage in-plant operations as well as the long-distance relationship between its remote water treatment facility and city distribution system.

• Membrane Aerated Biofilm Reactor Technology Validated For Title 22 Compliance

  Title 22 of California’s Water Recycling Criteria is among the strictest water treatment standards for water recycling and reuse in the United States. Fluence’s MABR demonstration plant was installed at the Codiga Resource Recovery Center (CR2C) in Stanford, California, in January 2018 for the purpose of third-party evaluation. The testing parameters included criteria to evaluate reliable enhanced nutrient removal in the form of Total Nitrogen, which is increasingly important across the United States and difficult and costly to achieve through conventional wastewater treatment.

• Connecticut Water Utility Successfully Removes 45% Of Trihalomethanes (THMs)

  While the addition of chlorine is one of the safest and most effective means for water disinfection, under certain circumstances chlorine in combination with naturally occurring organic compounds in water can lead to the formation of undesirable disinfection byproducts (DBPs).

• Shedding Light On Buried Infrastructure Management

  A longstanding U.S. EPA document on management challenges and strategies relating to the deterioration of buried drinking water infrastructure raises issues that are still very relevant today. Here are multiple thought-provoking perspectives on how to address those issues today, in order to protect both the investment in existing infrastructure and the health of the populations they serve.
