1. How Activated Carbon Works To Purify Air And Water 10/31/2019

   The first step is to define the performance limiting factors in the application. For this application, most of the adsorber is used for MTBE adsorption in the ppb concentration range. Adsorption of BTEX, TBA, or humic acids or other total organic carbon (TOC) components are removed by the front end of the column.

2. LC-MS/MS Analysis Of PFAS Extractables In Polyethersulfone Syringe Filters Using EPA 537.1 5/18/2022

   A key consideration for any PFAS method is to avoid contamination that can impact the accuracy of data, including those coming from sample preparation techniques such as filtration.

3. 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.

4. Removal Of Chloramines With Activated Carbon 12/30/2013

   In order to reduce the formation of harmful disinfection byproducts in drinking water, alternative disinfectant use has become increasingly widespread. Monochloramine is a leading alternative disinfectant that offers advantages for municipal water. This tech brief details the removal of monochloramine using activated carbon.

5. 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.

6. Innovative Solutions To Drinking Water Decontamination In Small And Medium Treatment Plants 9/21/2017

   Air stripping technology effectively removes VOCs, THMs, and CO2 for improved adherence to water quality regulations.

7. 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.

8. 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.

9. 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.

10. 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.
