1. 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.

2. Drinking Water Testing By Ion Chromatography Using Ultrapure Water 9/29/2022

   This application note demonstrates the suitability of ultrapure water produced by a Milli-Q IQ  7000 water purification system for the IC analyses of inorganic ions and DBPs in drinking water.

3. 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.

4. 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.

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. Free Chlorine Measurement In Drinking Water Treatment 12/21/2005

   Before water can be used as a safe and reliable source for drinking water, it must be properly treated. Since water is a universal solvent, it comes in contact with several different pathogens, some of which are potentially lethal, and inactivation is accomplished through chemical disinfection and mechanical filtration treatment. This treatment consists of coarse filtration to remove large objects and pre-treatment which includes disinfection using chlorine or ozone

7. ASM-10-HP Application Note 3/12/2026

   ResinTech ASM-10-HP is a strongly basic hybrid anion exchange resin specially formulated to selectively remove arsenic.

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. Aries Arsenic Reduction 1/7/2026

   Arsenic has no smell, taste, or color when dissolved in water even in high concentrations. It is a potential concern to those who live in areas with high natural deposits of arsenic, receive runoff from orchards, or from glass and electronic production waste.

10. 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.
