Installing Granular Activated Carbon Today To Prevent Regulatory Issues In The Future
Installing Granular Activated Carbon Today To Prevent Regulatory Issues In The Future

In 2010, Shelby County Water Services (SCWS) was planning for the future. With new regulations on the horizon, SCWS determined that the Talladega/Shelby water treatment plant in Shelby County, AL, needed more effective removal of disinfection byproducts (DBPs). Specifically, the treatment plant needed help complying with the U.S. EPA’s new Stage 2 Disinfection Byproduct Rule (DBPR).

  • FMCW Or ToF? Which Radar Level Technology Is Best For Tank Gauging In Custody Transfer Applications?
    FMCW Or ToF? Which Radar Level Technology Is Best For Tank Gauging In Custody Transfer Applications?

    Measuring the level of tanks used to hold fluids for custody transfer can be expensive. This is not due to the cost of the measurement instrumentation, but to what inaccurate measurements can cost the company. Picking the right instrumentation for applications is important. Which radar level technology should you choose for tank gauging in custody transfer applications? Frequency Modulated Continuous Waveform (FMCW) or pulsed Time-of-Flight (ToF or PToF).

  • Are You Experiencing Deviation Alarms In Your High Pressure Process Vessels?
    Are You Experiencing Deviation Alarms In Your High Pressure Process Vessels?

    In this white paper, learn how to decrease alarms due to redundant level devices not matching, especially in applications with high pressure and/or high temperature. The importance of Gas Phase Compensation (GPC) and how it affects level readings of guided wave radar (GWR) devices is critical. The presence of polar gas also can have an effect on the accuracy of any GWR that does not have GPC when installed in applications where high temperature or pressure is present. This paper will discuss these issues and address how to overcome them.

  • 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.

How Continuous Monitoring Helps Systems Grappling With Quality Issues How Continuous Monitoring Helps Systems Grappling With Quality Issues

As regulations become more stringent and increased demand is putting pressure on sources, traditional sampling to maintain water quality just isn’t cutting it anymore. Relying on periodic samples analyzed in a laboratory means water managers aren’t in touch with potentially large swings in the organic load and other problems flowing into their treatment plants. In this Water Talk interview, Kerim Kollu, an applications research scientist for Real Tech, discussed the emerging technology that is enabling municipalities to reliably perform continuous monitoring.

Advanced Testing For Better Biofilm Control In Distribution Systems Advanced Testing For Better Biofilm Control In Distribution Systems

Excessive amounts of diverse microorganisms, also known as biofilm, significantly impact water quality and promote corrosion in distribution systems. The fastest way for biofilm to proliferate is through ineffective management. However, taking control isn’t as simple as adding plenty of disinfectant to the water, and traditional testing involves sending samples to a lab and waiting days. In this Water Talk interview, Dave Tracey, director of strategic sales channels for LuminUltra, discusses innovative biological monitoring technologies that simplify testing so it can be done in the field with immediate results.

The Onset Of Water's Digital Transformation The Onset Of Water's Digital Transformation

The future of water looks daunting with the ever-looming challenges of population growth, climate change, and failing infrastructure, but the future also includes technological advances that can help overcome these hard-to-solve issues. The key, explains Water Talk guest and digital technology consultant Gigi Karmous-Edwards, is to embrace our digital capabilities as they continue to develop. We are already in the age of smart water, but the majority of utilities are not taking advantage of the power of data for optimizing operations and informing decision-making. It is only when wide-scale implementation occurs that the digital transformation arrives. In the interview below, Karmous-Edwards explains the impact on the horizon.
