Drinking Water Application Notes

31. 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.

32. 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
33. FLEX-TEND® Flexible Expansion Joints, Features And Specifications 12/3/2020

    FLEX-TEND® flexible expansion joints are designed to protect structures and pipelines from differential movement whether this movement is earthquake induced or the gradual motion of soil subsidence. This bulletin offers a concise listing and discussion of the important features and materials of the double and single ball assemblies.

34. 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

35. 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
36. 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.

37. Improved Efficiencies In TOC Wastewater Analysis For Standard Method 5310B And EPA Method 415 10/16/2014
    Total organic carbon (TOC) measurement is of vital importance to the operation of water treatment due to organic compounds comprising a large group of water pollutants. TOC has been around for many years, and although it is a relatively simple analysis in theory, operational efficiency is paramount.
38. Operations And LRV Calculations At Southwest Pipeline Project Drinking Water Treatment Facility 4/14/2016

    This presentation will discuss the operation of a 4 MGD pressurized two-stage Ultrafiltration (UF) plant over a 14 month period at the Oliver-Mercer-North Dunn (OMND) Drinking Water Treatment Facility, North Dakota.

39. 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. 

40. Groundwater Remediation 12/1/2020

    Good quality groundwater is an important natural resource. It provides drinking water for the public as well as process water for industrial applications. Groundwater can become contaminated through a number of ways including improper handling of process chemicals or disposal of wastes.
