The Smarter Water Manager

Communities around the world are facing a growing storm. Complex challenges including water scarcity, changing demographics, extreme weather patterns, and aging or overly stressed infrastructure are colliding to threaten critical water, energy, transport, enterprise and health networks. The water industry is in the eye of the storm.

  • How To Clean And Handle pH Sensors
    How To Clean And Handle pH Sensors

    For a pH sensor to maintain an accurate reading, the sensor must remain clean. Specifically, the glass measuring electrode cannot become coated, and the reference electrode assembly must not become coated, plugged or otherwise contaminated by the process solution. Here’s how to clean pH sensors to ensure correct operation.

  • Multi-Point Chlorination Process To Treat Raw Water Yields To A Multi-Barrier Chain Of Treatment Technologies
    Multi-Point Chlorination Process To Treat Raw Water Yields To A Multi-Barrier Chain Of Treatment Technologies

    For decades, a Winnipeg utility used a multiple point-chlorination process to treat raw water drawn from remote Shoal Lake. Concerns eventually arose about the potential presence of chlorine-resistant pathogens–Crytosporidium and Giardia–and residual disinfection byproducts, which coincided with encroaching development near the lake. The Clari-DAF system was selected and now removes 70 percent of the organics at the Winnipeg plant, which also improves filtration and extends the intervals between filter backwashes.

  • Ozone Vent Gas For Aeration At Wastewater Plant Expansion In China
    Ozone Vent Gas For Aeration At Wastewater Plant Expansion In China

    The Jimo, China, municipal wastewater plant was originally designed to treat a combination of municipal and textile wastewater (120,000 m3/d) with Class IB effluent limits for BOD, COD, ESS, TN, NH3-N and TP.

  • Carbon Dioxide For pH Control Of Landfill Leachate
    Carbon Dioxide For pH Control Of Landfill Leachate

    A landfill operator’s leachate treatment plant in Missouri required pH reduction following lime-softening and prior to the biological wastewater treatment process. Carbon dioxide (CO2) was chosen as a substitute for sulfuric acid due to improved process control and a reduced tendency to form scale.

  • In-Situ Oxygenation System Enables Increase In Capacity For Municipal Wastewater Treatment Facility
    In-Situ Oxygenation System Enables Increase In Capacity For Municipal Wastewater Treatment Facility

    To increase capacity within the existing footprint of a wastewater treatment facility in Michigan, two existing tanks were converted to aeration tanks with pure-oxygen aeration provided by Praxair’s In-Situ Oxygenation (I-SOTM) System.

    The City of Wilmington, Delaware is situated where the Christina River and the Brandywine Creek flow into the Delaware River.

  • High Turbidity Water Treatment Reached With Mobile Water System
    High Turbidity Water Treatment Reached With Mobile Water System

    Starting in 2010, the drinking water plant in Wellsboro, PA, began experiencing high turbidity and algae in the water which caused emergency notices for citizens to boil their water before use.

The Most Misunderstood Fact Behind Dissolved Oxygen Sensors (It’s The Pressure, Not The Concentration)
The Most Misunderstood Fact Behind Dissolved Oxygen Sensors (It’s The Pressure, Not The Concentration)

A dissolved oxygen sensor ought to be simple to understand. Whether it is membrane or optically based, it gives a signal that is proportional to the concentration of oxygen concentration in water.

DRINKING WATER ANALYSIS PODCASTS

Predictive Maintenance Enabled By Moving Secured Data To The Cloud Predictive Maintenance Enabled By Moving Secured Data To The Cloud

Cloud-based monitoring and reporting was all the rage at WEFTEC 2017. Water Talk sat down with Tom Perry, National Product Manager with Veolia to discuss Aquavista, one of the more established technologies for capturing critical data, storing it in the cloud and allowing it to be accessed real time, 24/7 from any smart, web-enabled device.

Real-Time Monitoring Aids Adoption Of New Water Treatment Technologies Real-Time Monitoring Aids Adoption Of New Water Treatment Technologies

With the ability to store mass amounts of data, real-time monitoring and the timely analysis of that data is spurring significant change in the water industry. As Rick Bacon, CEO of Aqua Metrology Systems, explains in this Water Talk interview, high frequency data is not only aiding in the battle to identify contamination but also in summarizing performance once a solution has been installed to fix it.

Microbial Contamination Monitoring For Water Distribution Systems Microbial Contamination Monitoring For Water Distribution Systems

Back in 2014, Louisiana’s Department of Health and Hospitals wrote an executive order for municipalities to boost their chlorine residuals as high as possible to burn off all biofilm and stop the outbreak of brain-eating amoeba (Naegleria fowleri) that had been detected as the cause of death in a number of individuals.

Water Regulations Change As Data Accuracy Intensifies Water Regulations Change As Data Accuracy Intensifies

It makes sense that water regulations are written in line with the available means to detect contaminants. The same logic would suggest that as newer, more accurate diagnostic technologies become available, the list of MCLs and the depth of water regulations will continue to evolve.

Mazzei Degas Separators Selected For Wichita Aquifer Project Mazzei Degas Separators Selected For Wichita Aquifer Project

A key component of the water supply plan for the City of Wichita, Kansas, was recharging the large aquifer that lies under the region with water from the Little Arkansas River. The river basin contains substantial farming operations which, during rain events, spike the river water with the commonly used herbicide Atrazine. Atrazine concentrations in the river frequently rose forcing the city to shutdown the bank filtration system. Advanced oxidation process (AOP) was selected to remove the herbicide. The AOP reactor’s design limited the amount of hydraulic backpressure it could tolerate. Consequently, Mazzei was challenged by the project’s design team to remove the entrained gas bubbles that remained from the prior oxidation treatment at a “not to exceed” hydrostatic backpressure of 19 feet.
