Drinking Water Application Notes

41. 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.

42. 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.

43. Real-Time Water Quality Data For Agriculture 9/23/2020

    We arm farmers with mission-critical water data to help enhance crop yield and taste. KETOS delivers valuable insights for fluctuations in deficiency and toxicity.

44. Bringing Efficiency And New Confidence To BOD₅ Analysis 2/4/2013

    Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.

45. Application Note: Low-Flow Sampling Of Water Quality Parameters Used In Determining Groundwater Stability 1/20/2010
    In April 1996, the U.S. EPA developed and published a document entitled Low-Flow (Minimal Drawdown) Ground-Water Sampling Procedures. The document states that “the most common ground water purging and sampling methodology is to purge wells using bailers or high speed pumps to remove 3 to 5 casing volumes followed by sample collection.” Adverse impacts can occur through this method affecting sample quality by increasing levels of turbidity. These problems can often be mitigated by using low-flow purging and sampling to reduce sampling-induced turbidity. By YSI
46. The Active Control Program For Advanced UV Oxidation 12/1/2025

    This application note will explore how active control programs lower operational costs of compliant contaminant removal. 

47. Hemodialysis Patient Health 10/29/2021

    Controlling dialysate quality is critically important to hemodialysis patient health. Complications as minor as nausea and fatigue or as severe as metabolic acidosis and sepsis can result if dialysate composition is incorrect. All the factors that ultimately affect dialysate composition must therefore be carefully monitored and controlled: proper proportioning and mixing of concentrates with water; the quality of water mixed with concentrates to form dialysate; and the quality of water used in the reprocessing of hemodialyzers, system maintenance and disinfection.

48. Performance Test Services For UV Advanced Oxidation Systems 12/1/2025

    UV AOP performance verification requires a robust test matrix covering design, operating, and control conditions. This process includes on-site execution, sample analysis, and troubleshooting to achieve successful regulatory approval.

49. 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.

50. Leak Detection On Water Distribution Network Using Clamp-On Flowmeters 5/22/2023

    A global engineering company realized that their leak identification methods were time consuming and expensive, and so began to explore alternative solutions, such as ultrasonic flow meters.
