Wastewater Measurement White Papers and Case Studies

  1. Replacement Vacuum Feeders For Hypo Treatment End Heavy Feeder Maintenance Burden At WWTP
    4/30/2014

    The instrumentation supervisor for the City of Baltimore, MD’s 150-MGD Back River wastewater treatment plant (WWTP) reports that replacement of problematic vacuum feeders with more advanced vacuum feed units has ended heavy maintenance burdens associated with sodium hypochlorite (hypo) treatment of plant effluent.

    Monitoring nitrates, total suspended solids and sludge volume concentrations ensures effluent quality, which is critical for meeting water quality standards for various regulatory agencies. By Endress+Hauser, Inc.

  4. A Helpful Guide To The Benefits Of The Single Rolling Diaphragm
    1/5/2017

    Reducing water loss and saving money are two of the highest priorities—and most consistent challenges—facing water professionals. Both of these issues stem from water pressure control.

  5. Reliable Flow Monitoring Of Primary And Secondary Sewage Treatment
    3/17/2016

    Primary and secondary sewage treatment are designed to improve the quality of wastewater. These processes reduce bacteria, suspended solids, biodegradable organics, and other materials to improve effluent quality.

  6. Continuous Monitoring And Control System Improves Communication, Operating Efficiency
    3/7/2007

    In the early 1990s, the Borough of Ridgway purchased several separate systems to control their water treatment and five bay filtration processes. Through the years, technology obsolescence led to difficulties in obtaining support and spare parts for all the systems. At one point, the existing systems completely failed, leaving Ridgway employees to manually operate the plant for several months. A new, more efficient system was desperately needed.

  7. Using Virtual Reference Grounding For Electromagnetic Flowmeters
    7/12/2012

    Electromagnetic flowmeters (EMFs) are the leading choice for recording the volume flow of electrically conductive liquids in a wide range of industries, including chemical, pharmaceutical, water/wastewater and food. By Ralf Haut, KROHNE, Inc.

  8. The Importance Of pH Measurement During Industrial Treatment
    9/18/2018

    Nearly every industry requires water and wastewater treatment to some degree. From food and beverage to pulp and paper operations, influent and effluent must meet certain conditions to adhere to regulatory and/or performance requirements, and water used during the process must conform as well.

  9. Ignition Gets Data Flowing For Water District
    12/26/2017

    Western Municipal Water District replaced their full SCADA system using Ignition.

  10. City Solves Reliability And Maintenance Problems For WTP Hypo Feeds
    8/13/2014

    A municipal water quality manager reports replacement of sodium hypochlorite (hypo) vacuum feeder units with a more advanced type at one water treatment plant (WTP) has helped allow for continued reliability for chlorination.
