Drinking Water Application Notes

  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. Determination Of Pesticide Residues In Honey, By An Automated QuEChERS Solution 9/17/2014

    The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

  3. Application Note: Troubleshooting A pH Electrode 1/26/2011

    Many factors affect performance of a pH electrode. When performance degrades, it is always a challenge for the analyst to identify the cause. Common troubleshooting procedures, which include evaluation of slope, electrode drift, time response, and accuracy, take considerable time. By Thermo Fisher Scientific

  4. A New Way Of Designing With Reverse Osmosis Membranes 7/23/2015

    Process design in water treatment is historically confined to proprietary or user-defined spreadsheets on a unit operation basis, with users manually adding results from each unit process upstream into the next operation.

  5. What Are You Doing To My Pipe: Can PVC Pipe Be Loaded? 4/13/2021

    The argument has been used that PVC pipe is delicate and can’t be subjected to any kind of loading. In EBAA's years of testing we have found that is not the case at all. PVC can take an extreme amount of strain.

  6. 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.

  7. Application Note: YSI Water Quality Monitoring Buoys Help Connecticut DOT Protect The Housatonic River 12/27/2005
    When replacement of the Sikorski Bridge spanning the Housatonic River was authorized, Paul Corrente and the Connecticut Department of Transportation (CT-DOT) set about the design and development of a water quality monitoring program to monitor the contractor’s in-water activities to insure full protection of the river from perturbation
  8. Deployment Of NextStep In Reverse Osmosis Systems 1/15/2026

    Pulsafeeder has secured a significant order for its NextStep series of stepper motor-driven metering pumps, specifically for use in advanced Reverse Osmosis (RO) applications. This deployment underscores the growing demand for precision chemical dosing in high-performance water treatment systems. The order includes NextStep NS1 and NS9 models, each selected for their unique capabilities in high-pressure and low-pressure RO environments.

  9. 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.

  10. Determining Biochemical Oxygen Demand (BOD) With Lovibond® OxiDirect 3/12/2026

    The Biochemical Oxygen Demand over a testing period of n days (BODn) is precisely defined and associated with experimental standards. It represents the quantity of oxygen aspirated in the course of aerobic breakdown of organic substances by microorganisms.
