Drinking Water Measurement White Papers and Case Studies

  1. Are Test Strips Still Relevant For Water Analysis?
    9/26/2017

    Today’s environmental laboratories are audited and accredited companies where quality control (QC) and quality assurance (QA) reign. Advanced technology is needed to measure parameters for regulatory compliance down to parts per billion. In a world of regulatory mandates, can test strips still be used for water analysis?

  2. Need Water Quality Assurance? UV254 Can Help
    5/21/2009
    Superior water quality, it is why we treat our waters. All around the world we are continually striving to improve the safety of our drinking water to protect public health. However, how are we assuring the success of our efforts? UV254 testing provides valuable assurance about your water quality by detecting organic matter in water. This is something that turbidity can’t do. Just because you have low turbidity does not mean that you will have low organics. By Real Tech Inc.
  3. Town Of Hillsborough Relies On Hach For Free-Ammonia Testing And Nitrification Control
    1/8/2012
    When Bay-area water wholesaler San Francisco Regional Water System (SFRWS) changed its residual drinking water disinfection process from chlorine to chloramine, the town of Hillsborough’s Water Quality staff faced the challenge of updating its water testing procedures to prevent nitrification and continue to meet state-mandated drinking water quality standards.
  4. Utilizing A Phosphate Analyzer To Monitor And Control Chemical Feed Reduces Operating Costs And Improves Reliability
    2/6/2014

    The Environmental Protection Agency (EPA) administers the Safe Drinking Water Act (SDWA), which provides for the enhancement of the safety of public drinking water supplies through the establishment and enforcement of nationwide drinking water regulations. Congress gave the primary responsibility for establishing regulations to the U. S. EPA.   Until 1990, the EPA administered a certification process for chemicals, including phosphates, to be used for potable water treatment. By Randy C. Turner, Technical Director, Swan Analytical USA

  5. The Eaton M-Max VFD Provides QuantumFlo With A Cost-Effective, Energy Efficient Solution
    4/26/2017

    Achieving consistent water pressure is a challenge for geographical areas that have grown faster than the development of infrastructures to accommodate water demand and for businesses such as fast food restaurants and strip malls.

  6. Understanding Head Loss … And Why It Matters
    2/2/2018

    Satisfying water purification and volume requirements at the treatment plant or wellhead are not the only cost-performance impacts on physical operations. There are other variables related to distribution operations that affect head loss and energy costs throughout a distribution system. Here are several strategies for identifying, calculating, and minimizing head loss.

  7. The Next Generation In Water Filtration For The Oil And Gas Industry
    4/17/2013

    There is a need in many segments of the oil and gas production industry for an improvement in water filtration over traditional methods. By Michael Dejak, P.Eng. 

  8. Precise Biogas Flow Measurement
    4/25/2016

    As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas. By Scott Rouse, VP Product Management, Sierra Instruments

  9. An Energy System For Power Generation Relies On Quality Monitoring Instruments From Siemens
    11/23/2015

    A U.S. company develops energy technologies that are environmentally sustainable and provides their customers with the ability to use their energy sources in a more practical and cost-effective manner.

  10. Utah Water District Saves Time And Resources, Improves Accuracy By Upgrading Sensors And Analyzers
    7/20/2015

    Monitoring chlorine and fluoride levels in the drinking water of Utah’s Taylorsville-Bennion Improvement District used to be expensive, labor intensive, and often sensitive to interference from the vari­able frequency drives used to operate the chlorine injection pumps. That is, until the district upgraded to Rosemount free chlorine and fluoride sen­sors and analyzers from Emerson.
