Wastewater Application Notes

  1. 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).

  4. Application Bulletin: Reverse Osmosis
    3/19/2008

    Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached

  5. 3M™ Liqui-Cel™ Membrane Contactors Are Widely Used In The Soft Drink And Brewing Industries To Control Dissolved Gasses
    7/10/2017

    Gas control is an important concern in the beverage industry. Oxygen in the water can oxidize flavor components and shorten the shelf life of the product. Carbon dioxide can also have an impact on taste and pH of the product.

  6. Analysis Of Pesticide Residue In Spinach Using The AutoMate-Q40 An Automated QuEChERS Solution
    10/16/2014

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

  7. Optimizing Air Flows To Aeration Basins
    4/17/2014

    As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then used as fuel in the cogeneration process. However, a clean environment calls for not just clean air and clean energy, but clean water as well.

  8. 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.

  9. Pipe Repair On A Budget
    3/7/2014

    A new pipe-repair solution promises to save time and money, while also being sustainable, long-lasting, fully scalable, and safe for workers.

  10. Primary Wastewater Treatment: Influent Monitoring
    11/10/2013

    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.
