Wastewater Treatment Solutions

  1. Iron Salts 7/15/2024

    Iron salts are a proven technology for long-duration hydrogen sulfide control in collection system gravity and forcemains; solids processing units, solids transfer lines and anaerobic digesters. They have been used for over 30 years in hydrogen sulfide control applications and are a well understood technology.

  2. Why Measuring Hydrogen Sulfide In Wastewater Matters 7/11/2024

    Hydrogen sulfide (H2S) gas in wastewater environments is a familiar concern. But waiting until its odor is detected can be too late to exert as much control over it as desired. Fortunately, a new ability to monitor H2S concentrations — in the liquid wastewater stream, in real time — is advantageous for wastewater professionals in terms of safety, cost, and consumer complaints. Here are four ways to capitalize on that capability.

  3. Biosolids Odor And Corrosion Control 7/8/2024

    For more than 20 years, USP Technologies’ comprehensive biosolids odor and corrosion control solutions have been extremely effective at reducing sulfides and other odor causing compounds in municipal and industrial wastewater treatment systems.

  4. GS1440 Sensor H2S 7/8/2024

    Water or air, measure H2S where it matters – right at the source.

  5. Achieving A Delicate Balance To Maintain RO Membranes 7/8/2024

    This application note explores the importance of maintaining a delicate balance in reverse osmosis systems to protect RO membranes.

  6. Comparison Of Ultra Low Range Total Chlorine Residual Limits Of Detection And Quantitation Across The Water Industry 7/8/2024

    Limits of Detection and Quantitation are key to understanding analytical instrumentation capabilities, especially when non-optimal process control can lead to damage of sensitive equipment due to insufficiently accurate readings.

  7. Is ORP Really Your Best Option For Dechlorination Measurement? 7/8/2024

    In this application note, explore considerations for achieving more reliable accuracy when quantifying dechlorination results for applications ranging from RO membrane protection to wastewater discharge compliance.

  8. Nutrient Removal 6/28/2024

    Phosphorus and nitrogen, while necessary elements for life, when concentrated in the effluent of a wastewater treatment plant, are harmful to the environment, especially aquatic plants and animals. When concentrated amounts of these elements enter bodies of water, it causes algae blooms, which reduces dissolved oxygen in the water and can be damaging to animal populations. It can be a very serious problem for natural areas downstream of industrial or municipal discharge.

  9. PRI-CEPT® Phosphorus Removal From Wastewater 6/28/2024

    When applied to plant influents, hydrogen peroxide destroys dissolved and/or total sulfide that otherwise scavenges Fe3+ added for CEPT and/or chemical phosphorus removal from wastewater. The foundational aspect of this PRI-TECH application (called PRI-CEPT) is that one lb of total sulfide theoretically consumes 3.5 lbs Fe3+ and thus represents an additional cost of $2 – 3 per lb influent sulfide.

  10. PRI-SC® Technology 6/28/2024

    Sulfide odor control within sanitary sewers has been practiced for over 50 years, yet only recently have substantive advances been made. Where once the choice of chemical treatment was either chlorine or iron salts, safer and more environmentally benign technologies based on nitrates, hydrogen peroxide, and/or magnesium hydroxide have gained acceptance. These new alternatives, however, can increase treatment costs substantially and present limitations in themselves. Therefore, it makes sense to explore new avenues for lessening the adverse impacts of the older, cheaper mainstays, particularly iron salts (ferrous/ferric chloride or sulfate) that provide other benefits to wastewater treatment operations.
