Drinking Water Case Studies and White Papers

  1. City Of Springfield, MO, Upgrades Disinfection System From Gas Chlorine To On‐Site Sodium Hypochlorite Generation 7/24/2018

    In April 2013, City Utilities started up three Microclor Model MC‐1500 skid systems, each rated at 1,500 pounds per day of free available chlorine.

  2. Membrane Treatment Of Groundwater 4/2/2015

    The groundwater that a southern Louisiana water utility supplies to local residents has traditionally carried a high amount of organic material and color. In the past, the organics were oxidized and broken down by chlorination, but this practice had gone out of favor due to production of disinfection by-products (DBPs) such as Trihalomethanes (THMs) and Haloacidic Acids (HAAs).

  3. A More Cost-Effective Tool For Oxygen Injection Flow Measurement 4/23/2021

    Variable area (VA) flow meters offer an economical solution in many hazardous wastewater applications, as well as a variety of other uses, but are often overlooked by engineers and plant operators who think a higher level of flow measurement technology is necessary. 

  4. Why Static Metrology Is Important In A Modern Era 4/10/2023

    As sustainability, climate change resilience, and the overall increasing cost of water increasing come into focus, the needs of water utilities and their customers have shifted.

  5. Filtration That Works: Proven Solutions For Clean, Reliable Water 4/21/2025

    This article explores various real-world applications of Harmsco’s filtration solutions, highlighting how tailored filtration systems improve water quality, reduce maintenance costs, and enhance operational performance across industries.

  6. Simple And Smart: How Radio-Read Meters Are Improving Meter Reading 4/22/2020

    When Hank Zwart took over as director of public works in 2014, the city was in the initial phases of installing a walkby system that was eight-year-old technology. Knowing this older metering technology is not the best way forward, Zwart and the City of Prescott decided to implement the latest AMR technology that supports future migration to AMI. To meet this goal, City of Prescott chose Kamstrup’s READy AMR system.

  7. Why It's Time To View Plastic Pipe In A Whole New Light 12/23/2019

    Because recent advances in plastic materials and processing have led to a new generation of plastic piping systems to handle challenging water and chemical environments, it is important to understand why some older piping choices might no longer be the best bet. Here are some key reasons to consider new plastic-piping choices for municipal and industrial water/wastewater applications in a whole new light.

  8. How To Utilize pH Neutralization Systems And Adhere To Discharge Regulations 9/17/2018

    For any drinking water or wastewater treatment operation, pH neutralization is never far from top-of-mind. The regulatory standards for pH to which effluent must adhere, also known as “pH neutralization,” are central to ensuring that treatment is performed accurately and that the water or wastewater leaving a plant is safe.

  9. Testing Better Paths To Contaminant Control 8/10/2020

    As a utility, it is tough enough to be notified that you need to remove a new contaminant of emerging concern (CEC). It’s even harder without having a complete picture of what is involved. 

  10. AMERICAN Flow Control's Semper™ RPM With “Lift And Shift” Capability Helps Lowcountry Regional Water Resolve System Pressure Issues 5/5/2021

    In the summer of 2020, the Lowcountry Regional Water System in Hampton, South Carolina, had a customer located in an industrial park report a low water pressure issue. The company was a commercial laundry that served the hospitality industry and provided linens to hotels around the Hilton Head area. The low water pressure issue was causing the company’s heat recovery system to work improperly shortly before the July 4 holiday. In its first use of the AMERICAN Flow Control SEMPER™ Remote Pressure Monitor (RPM), Lowcountry Regional Water System deployed two units to resolve the issue. One device was located on the water system’s side of the meter and the other device was placed inside the company’s building, where water enters the facility at the backflow preventer.
