DRINKING WATER CASE STUDIES AND WHITE PAPERS

• Connecting The Water Cycle: Bridging The Physical-Digital Gap

  There are many reasons why an AMI system might fail, but more often than not it boils down to gaps in the physical-to-digital transition.

• Filter Membrane Predictive Maintenance

  At manufacturing operations using ultrafiltration systems, the ultrafiltration membranes are used for numerous batches without replacement, using Clean-In-Place (CIP) operations in between batches to maintain filter performance. However, ineffective CIP cycles or long-term fouling or degradation of the filter membrane can result in increased cycle times to move the desired amount of product through the filter, lost yield as the product is unable to permeate the filter, or poor product quality as membrane failure may occur.

• Energy-Efficient Blowers Help Clean Riachuelo River

  Cleaning tannery effluent is an energy-intense process. The Curtidor Industrial Park (PIC) has found a way to keep energy usage and costs down while reducing pollution in the Riachuelo River.

• Innovative Repair Products A Key To Optimized Asset Management

  For water managers, getting visibility into their distribution system through historical data offers a better understanding of which pipes are most likely to break, thereby making it easier to plan to make repairs before they become emergencies. Active leak detection can also reduce the number of emergency repairs by finding them when they are small leaks. A growing number of municipalities are taking advantage of those tools. At the same time, however, selecting optimal repair products plays just as critical a role in enhancing asset management.

• AFC Semper RPM: Topsfield Water Dept.'s Answer For Identifying Water Hammer

  For any water system, water hammer, also known as pressure transients, pose significant threats, from leaking joints to service connection failures and even pipes that burst. The damages resulting from these events can be costly to repair and leave customers without water.

• Historic Town Builds A “Smart” Water System With ORION® Cellular And BEACON® Software as a Service (SaaS)

  Paducah Water in Kentucky identified a need to upgrade its water system. The utility used a manual reading system for decades and investigated multiple solutions, including touch-read and drive-by systems. None of the solutions met its requirements. “In both of our attempts to deploy new solutions, we found the equipment and systems to be unreliable. We even had to stop our implementation efforts after having installed 1,000 new water meters,” said Bill Robertson, general manager of Paducah Water. “We had to keep looking.” Read the full case study to learn more.

• Understanding ISE Measurements In Wastewater Process Monitoring

  Analytic measuring technique provides a huge number of procedures to determine the concentrations of substances in an unknown sample, e.g. photometry, titration or mass spectrometry.

• Careful Management Of Our Water Supply Reduces Water Stress

  Every year the UN works to highlight the importance of one of our most precious natural resources on World Water Day. This year the UN’s campaign calls on people to share what water means to them. Thirst quenching, life giving and cleansing, it is significant to us all. Close management of our water supplies can ensure there is enough for everyone.

• The Hidden Dangers Of Manganese In Drinking Water

  Evidence indicates that manganese (Mn) is more than a nuisance: it's a threat to health. It's time to get serious about removing it from drinking water.

• The Challenge Of Flow Disturbances On Meter Accuracy

  Accurately measuring flow is critical for water utility operations. Also, regulatory agencies mandate flow monitoring and require annual calibration of meters. But even a meter in perfect condition and properly calibrated can read inaccurately. Flow disturbances are a common cause of accuracy and repeatability errors.
