Wastewater Application Notes

  1. Aerated Biological Nitrogen Removal 7/16/2013

    Excess ammonia in receiving waters causes algal blooms that decrease oxygen levels. For this reason, many wastewater treatment plants (WWTPs) must limit ammonia in discharge. Mike Rousey, Hach Company

  2. A Comparative Study Of On-Line And Laboratory TOC Analyzers For Analysis Of Municipal Wastewater 2/7/2014

    This application note presents comparative data obtained on influent and effluent wastewater samples using laboratory and on-line TOC analyzers employing the heated sodium persulfate oxidation technique in USEPA-approved methods 415.3 and SM 5310C.

  3. Monitoring IWW Effluents With FP 360 sc Oil-In-Water Sensor 5/14/2024

    This application note explores a test which demonstrated significant improvements in Oil-in-Water monitoring of industrial wastewater in comparison to the weekly grab sample analysis method.

  4. Removal Of PFCs With Activated Carbon 12/30/2013

    In recent years, various perflorinated chemicals (PFCs) have come under increasing scrutiny due to their presence in the environment, in animals, and in human blood samples. There are two major classes of PFCs: perfluoroalkyl sulfonates such as perfluorooctanesulfonic acid (PFOS) and long chain perfluoroalkyl carboxylates such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA).

  5. Simplify And Optimize Your Process With Level And Pump Control 3/1/2022

    Level controllers have evolved to meet today’s environmental challenges and industry demands. Learn how they support improved process management and, ultimately, a better bottom line.

  6. Wet Weather Treatment Using AquaStorm® Cloth Media Filtration 6/4/2025

    This application note from Aqua-Aerobic Systems highlights the effectiveness of the AquaStorm® Cloth Media Filter as a flexible, compact, and highly efficient solution for Combined Sewer Overflow (CSO) and Sanitary Sewer Overflow (SSO) events.

  7. Lab Gas Sub-Metering Accuracy Improves With Thermal Flow Meters To Save Money 12/1/2017

    Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.

  8. Repair Or Rethink 8/7/2015

    The Moundsville Wastewater Treatment Plant in West Virginia chooses not to fix a broken blower unit, but rather to correct an outdated approach. The result is a savings of $50-60K a year in energy costs.

  9. Dissolved Oxygen Measurement In Wastewater Treatment 11/11/2013

    A wastewater treatment plant separates solids from the liquid, and consists of two basic stages: primary treatment and secondary treatment.

  10. Veterinary Drug Residue Analysis Using The AutoMate-Q40: An Automated Solution To QuEChERS 10/1/2014

    QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.
