DRINKING WATER ANALYSIS RESOURCES

• Ribbon-Cutting, Blessings, Water Bubbles Open New Hydro Building

  New home for water quality lab opens new horizons for innovation, research and teaching.

• Top 6 Reasons To Consider Zeta Potential

  In this article, explore the top reasons you should consider a laboratory zeta potential system for coagulation dose control. 

• U.S. PFAS Analytical Instrumentation Market Expected To Generate Profound Growth Over Next 7 Years

  The current slope of the U.S. PFAS analytical instrumentation market advancement is steep due to U.S. EPA plans to propose water and wastewater regulations for PFAS. Additionally, some of the key drivers include an increased awareness about the widespread prevalence of PFAS contamination, public outrage, funding, and litigation scares.

• Water Sustainability: What Companies Are Promising And How They Can Deliver

  Water sustainability, conservation, and resiliency have become essential focus areas for many companies. While the US was once a water-rich country, certain areas are seeing what used to be an abundant resource become scarce.

• Calling On Utilities To Combat Legionella

  The risk level linked to delivered drinking water from municipal utilities is very small, even if some high-profile examples of failure (see Flint, MI) have degraded public confidence to a degree. Our treatment professionals usually hit their targets, so the onus then shifts to the research and guidance that determines the safe level of various constituents through U.S. EPA protocols. But there is one contaminant that rulemaking hasn’t quite caught up to and which is downright deadly — Legionella pneumophila.

• Optimal Coagulant Dosage Control Of Raw Water

  The following describes how combining of the latest data management and process management solutions can optimize the coagulation process. Coagulation is influenced by several raw water parameters. This new approach uses a feedforward model with machine learning of several raw water parameters for optimal coagulant dosage control. In addition, feed-back control can be used to trim the feed-forward model. In 2020, utilities that have installed the coagulation optimization system have achieved approximately 10% reduction in coagulant dosage while achieving similar settled turbidity.

• SWAN Corner: Unlock Data To Improve Water Distribution System Operations

  Water distribution system infrastructures are designed to deliver drinking water to end users, but utilities are continually faced with distinct challenges to fulfill this fundamental objective. For example, these utilities improve customer service by delivering water with high pressure, but on the other hand, water conservation policies push them to minimize water distribution leaks. For this reason, water utilities invest heavily in SCADA and telemetry technologies to support operational decisions. However, unlocking historical operational data and fusing it with other data (such as billing information from AMR/AMI networks) to generate actionable insights has proven difficult.

• Legionnaires’ Disease: How IoT Solves For Property Risks Emerging From The Pandemic

  Last year, COVID-19 emerged as a global health threat, in more ways than one. In additional to the toll posed by the virus itself, the pandemic presents a number of other safety threats as priorities and resources shift to tackle the larger concern at hand. In particular, as buildings shut down to accommodate stay-at-home orders, property teams may be suspending routine maintenance tasks for the time being, which enables harmful bacteria to spread until workforces return.

• Durham, NC Improves Water Quality With Remote Pressure Monitoring, Sampling, And Flushing Stations

  The City of Durham is committed to providing safe drinking water to a service population of more than 289,000.  The City’s Department of Water Management (DWM) ensures the delivery of water to approximately 99,000 service connections through 1,400 miles of watermains. Lake Michie and Little River Reservoir are the two sources that deliver raw water to the City’s two treatment plants, using a combination of gravity flow and electric and hydro-powered pumping systems. Together, these plants have the combined treatment capacity of 64 million gallons per day (MGD) with an average demand is 28 MGD.
