Wastewater Application Notes

  1. Dissolved Oxygen Measurement 11/11/2013

    One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

  2. How To Optimize Your DAF System With Air Dissolving Pumps 9/6/2024

    Despite their importance in modern wastewater applications, not all DAFs are created equal. Factors, such as the components that make up these systems, will influence how well they work and how long they last.

  3. Pikeville, Kentucky Medical Center Leak Found Despite Ambient Noise 6/23/2021

    Leaks found in 60 psi high density PE pipe by FELL in less than three hours. Acoustic and CCTV failed to find any leaks after more than a year of investigation. Read the full case study to learn more. 

  4. Dosing Of Sodium Hypochlorite Solution For Drinking Water Disinfection 9/22/2022

    A water purveyor was in urgent need of a chemically resistant flow instrumentation with a long life of service that allowed reliable and long-term stable dosing of the sodium hypochlorite solution.

  5. WWTP Utilizes Online Instrumentation And SCADA To Keep Operating Costs Low And Effluent Quality High 2/6/2013

    Providing the best value to wastewater customers requires a team of operators that have a deep sense of ownership and are committed to continuous improvement. Such is the case for the operating staff at one wastewater treatment plant whose progressive attitude and a philosophy of “do it right” led them to an investment in online instrumentation and SCADA for compliance, monitoring, and control.

  6. Active Energy Control – Energy Reductions Of Up To 10% Above Standard Drives 4/1/2017

    Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.

  7. Mapping And Identifying The Source Of Water Quality Issues 6/28/2017

    A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

  8. Performance Test Services For UV Advanced Oxidation Systems 12/1/2025

    UV AOP performance verification requires a robust test matrix covering design, operating, and control conditions. This process includes on-site execution, sample analysis, and troubleshooting to achieve successful regulatory approval.

  9. Process Monitoring And Control For Increased Productivity And Efficiency 4/9/2012

    The Littleton/Englewood wastewater treatment plant, Colorado, put in place processes to effectively monitor the levels of ammonia in their wastewater treatment.

  10. Reducing Total Phosphorus In Water Resource Recovery Facilities 9/10/2014

    Monitoring phosphate during the wastewater treatment process allows for fine-tuning and optimizing chemical dosing for removal of phosphate, which provides significant cost savings to the plant while protecting the aquatic environment downstream of the facility.
