Drinking Water Application Notes

51. Why Should We Care About NSF/ANSI 61 Certification? 3/17/2021

    According to National Sanitation Foundation (NSF) and the American National Standards Institute (ANSI), it's a set of standards relating to water treatment and establishes criteria for the control of equipment that comes in contact with either potable water or products that support the production of water.

52. 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.

53. A Comparative Study Of On-Line And Laboratory TOC Analyzers For Analysis Of Raw And Finished Drinking Water 4/5/2013

    Total organic carbon (TOC) analysis is an important indicator of water quality throughout the drinking water treatment process. Raw source water is progressively treated in chemical coagulation, flocculation, sedimentation, and filtration steps to remove particulate matter and natural organic matter (NOM).

54. Ion Exchange Resins And Activated Carbons For Better-Tasting Water 12/18/2013

    For many, access to good-tasting tap water is limited, and buying bottled water can be expensive. Simple pour-through jug filters offer a low-cost and effective alternative. Activated carbons, in conjunction with ion exchange products, produce drinking water that is absent of all industrial pesticides and contaminants.

55. Network Monitors Water Quality In Shale Gas Drilling Region 9/2/2011
    High-pressure injection of water, sand, and chemicals that fracture shale deposits deep underground to free trapped natural gas is employed by drillers tapping the Marcellus shale beds, a geologic deposit that stretches from central New York to Virginia and contains gas believed to be worth hundreds of billions of dollars.

56. 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.

57. 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.

58. 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.

59. LC-MS Analysis Of PFAS Compounds In EPA Methods 537.1, 533 And 8327 11/4/2021

    The Ascentis Express PFAS HPLC column is designed for the separation of novel and legacy PFAS as per recent EPA methods. A specific PFAS delay column prevents background PFAS contamination from interfering with sample results in quantitative LC-MS methods.

60. Phosphate Corrosion Control In Drinking Water 11/21/2012

    Corrosion occurs because metals tend to oxidize when they come in contact with oxygenated water, resulting in the formation of stable metal oxides.
