Wastewater Application Notes

  1. Membrane Degassing and Debubbling of High Viscous Fluids with 3M™ Liqui-Cel™ Membrane Contactors

    Increased gas content often leads to problems with bubble formation in highly viscous fluids. 3M™ Liqui-Cel™ Membrane Contactors can provide a simple, compact, and efficient in-line solution for removing bubbles from viscous liquids before they create problems in a process operation.

  2. Improving Compliance Through Real-Time Phosphorus Control

    Levels of phosphorus, a chemical element that promotes organic growth, must be controlled in wastewater coming from beverage, food and dairy processing plants. Failure to control phosphorus accurately has a negative impact on water quality and can lead to large fines.

  3. 3M™ Liqui-Cel™ Membrane Contactors Improve Water Quality and EDI Performance

    Electrodeionization (EDI) is a widely used water treatment process. EDI technology is an electrochemical process that uses ion selective membranes and an electrical current to continuously remove ions from water. The process uses ion exchange resin to remove the ions from the feed stream, producing pure water.

  4. Active Energy Control – Energy Reductions Of Up To 10% Above Standard Drives

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

  5. Increase Ink Jet Print Speeds By 15% With 3M™ Liqui-Cel™ SP Series Membrane Contactors

    Many high-speed, wide-format ink jet printer manufacturers are now using 3M™ Liqui-Cel™ SP Series Membrane Contactors to remove air bubbles and excess gases from ink to reduce downtime and improve yields. Entrained bubbles and excess gases are often the cause of printing surface defects and ink flow interruptions that can cause printer shut-downs.

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

    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.

  7. Ion Exchange Resins Reduce Pollution From Refineries

    A single operational oil and gas refinery produces millions of gallons of contaminated wastewater a year, leading to environmental pollution concerns. Ion exchange resins are a metal- and ion-removal solution to help clean this wastewater for plant reuse or safe disposal. This application guide explains how resins can be used to demineralize refinery water in process, boiler, and cooling water applications.

  8. Analyzing Total Organic Carbon In Sea Water

    The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

  9. Primary Wastewater Treatment: Influent Monitoring

    The raw sewage entering a wastewater treatment plant comes from a variety of sources. In addition to effluent from domestic users, effluent from industrial users and storm water run off can be present.

  10. Precipitant Savings Through Optimized Phosphate Elimination With Integrated Predictive Diagnostics

    Dosing of the precipitant was adjusted manually based on the laboratory measurement value of the daily composite sample and so was unable to respond to possible peaks. Although being compliant with the effluent limits, the values observed fluctuate between 0.2 and 0.8 mg/L.
