  1. The Role Of Zeta Potential In Water Treatment Process Control 5/27/2020

    Physical processes such as sedimentation, flotation and filtration remain at the heart of most process trains for the treatment of water and wastewater flows.

  2. LC-MS Analysis Of 33 PFAS Compounds In 5 Minutes 11/4/2021

    In response to environmental testing demands for faster LC-MS analyses, the new Ascentis® Express PFAS HPLC and delay columns allow the highly efficient separation of 33 PFAS compounds in 5 minutes with reduced background contamination.

  3. Application Note: Ozone Measurement In Potable Water 3/1/2010

    Ozone is a powerful oxidizing agent that can be used to destroy the organic compounds that affect the taste and odor of potable water. Environmental concerns have led to increased use of ozone because, unlike chlorine, it does not form hazardous by-products.

  4. Bardac® LF 18 — A Novel Cooling Water Algaecide 10/23/2020

    The active ingredient in Bardac® LF 18 is dioctyl dimethyl ammonium chloride. This product comes in two concentrations: -10WT (10% w/w) and -50WT (50% w/w). Several chemical properties of this product yield key benefits that set it apart from other industrial cooling water products. It is a quaternary ammonium compound (quat). Quats are typically low cost and highly effective biocides for a broad spectrum of organisms.

  5. Optimization Of Water Treatment Using Zeta Potential 5/27/2020

    Drinking water in the US and developed nations of the world is treated to remove contamination of foreign materials, both mineral and organic.

  6. LC-MS Analysis Of PFAS Compounds In EPA Methods 537.1, 533 And 8327 11/4/2021

    The Ascentis Express PFAS HPLC column is designed for the separation of novel and legacy PFAS as per recent EPA methods. A specific PFAS delay column prevents background PFAS contamination from interfering with sample results in quantitative LC-MS methods.

  7. Secret To Disinfection Monitoring For High Chlorine Residual Wastewater Applications 8/2/2015

    Some wastewater applications require chlorine residuals greater than can be effectively monitored using DPD due to the oxidation of the Wurster dye to a colorless Imine. Such applications include industrial wastewater processes that inherently have a high chlorine demand thereby requiring a more robust monitoring method.

  8. Activated Carbon And Adsorption Of Trichloroethylene (TCE) And Tetrachloroethylene (PCE) 12/30/2013

    Trichloroethylene (TCE) and Tetrachloroethylene (PCE) are two of the most common solvents that contaminate groundwater supplies in the United States. Both solvents see frequent use in the extraction of fat, in the textile industry, in the production of various pharmaceutical and chemical products. TCE is also used as a degreaser from fabricated metal parts, and PCE serves as a component of aerosol dry-cleaning solvents.

  9. Municipal Real-Time Water Quality Monitoring 9/24/2020

    We arm municipalities with actionable data necessary to make informed decisions about water quality in their communities
