Free Webinar: Paradigm Shifts in Water Quality Sensor Design

Data from continuous water quality monitoring networks inform critical activities across every sector of the surface water industry today, from meeting federal and state water quality standards and ensuring safe recreational waters, to researching and managing the effects of climate change. As such, continuous water quality monitoring networks must produce results that meet the data quality objectives for a given program while operating within the constraints of limited human resources and budgets.

Until now, however, deploying and cost-effectively maintaining an autonomous monitoring network has been limited by lack of advancements in sensor technology.

Join David A. Bossie for a free online training webinar exploring how innovations in water quality sensor design are challenging old beliefs about the ability of autonomous, long-term monitoring networks to produce representative, comparable data at a price point within reach of most organizations.

Specifically, we’ll learn how you can operate pH sensors hands-free for months that previously required calibration every 1-2 weeks.  We’ll see how turbidity sensor accuracy is no longer worrisome due to improved linearity across the range of 0-4000 NTU, and how the use of LEDs and filters provide stability not found with incandescent light sources.  Finally, we’ll explore how you can deploy conductivity sensors in biofouling environments without loss of accuracy thanks to an innovative, open-faced design that allows wiping.

Learning Objectives
Attendees can expect the discussion and education of the following learning objectives:

  • Learn how limitations of existing technologies in continuous water quality-monitoring networks affect data quality and network maintenance costs.
  • Explore how the evolution of the pH sensor design results in improved stability, data quality and reduced calibration frequency.
  • Discover how improved turbidity sensor design increases linearity and accuracy in clear and high sediment environments.
  • Examine how improved conductivity sensor design coupled with anti-fouling systems improves performance in high biofouling environments.

On the Pulse – Smart meters and acoustic sensors limit non-revenue water loss.

The town of Olds in Alberta, Canada, faced a daunting task. The public works and utilities department, serving the town of approximately 8,000, set out in 2007 to decrease the municipality’s total water usage by 10% by January 2017, using the amount of water it consumed in 2006 as a baseline.

To meet this goal, town officials knew that they would have to address the water that leaked out of Olds’ water delivery system each year. And in this challenge, Olds is far from alone.

According to information published by energy and water resource management company Itron, more than 32 billion cubic meters of treated water leak from urban water supply systems across the world every year. That is equal to more than $18 billion of non-revenue water.

Cost-Saving Strategies for Water Utilities – Forester Network

Please note that the article Cost-Saving Strategies for Water Utilities – Forester Network was written by Carol Brzozowski for March 10, 2017.

Water utility operators face many financial hardships these days. Today, cash-strapped utilities are challenged to deliver optimal levels of service while saving money on water treatment costs.

Treatment costs are not isolated and must be considered as part of the overall cost of water service, points out Brian Bokowy, business manager CIM for AllChem Performance Products. “Water utilities—particularly utilities that have multiple locations and multiple well sites, booster stations, and multiple treatment areas—have all of the logistics of transportation, storage, handling, and safety concerns of securing all of those individual sites,” notes Bokowy.

Oftentimes, safety concerns will dictate more than one employee going out to a site whenever chemicals are being handled, he adds. “All of these additional visits out to sites, all of the additional safety and handling concerns, add real costs to chlorinate that water for the municipality,” says Bokowy.

“By moving to safer, less hazardous chemicals, it reduces costs by eliminating some of the storage concerns, and eliminating some of the extra personnel and trips out to the sites that may be involved with the manhours associated with going out to those sites.”

AllChem Performance Products specializes in chlorination equipment, especially tablet feed systems. The systems are designed as an effective way to chlorinate drinking water and wastewater without the costly safety and hazard concerns associated with handling, transporting, and treating with gas chlorine or liquid chlorine sodium hypochlorite, notes Bokowy.

One system offered by the company is the PTF-100 Feed System, consist­ing of the Horizon PTF-100 Tablet Feeder and Horizon 90 PT Tablets.
