Drinking Water Measurement

  1. Benefits Of Off-Line Calibration Of pH And ORP Meters
    7/17/2018

    One of the most commonly used measurements in the water and wastewater industry is pH. A measurement of how acid or alkaline a substance is, a pH reading can instantaneously indicate a problem with the water. Another common and useful measurement is oxidation-reduction potential (ORP). Treatment facilities use ORP sensors to optimize disinfection and biological nutrient removal processes.

  2. Instrument Resiliency For Tough Times

    Utilities have relied on numerous instruments for process control and monitoring for many years. But in today’s world, instrumentation is more crucial than ever. Most treatment facilities, pump stations, and other system components are automated to some extent. Instrument failure or inaccuracy may result in serious public health or environmental consequences. Resilient instruments can power through adversity and keep utilities running smoothly.

  3. Operational And Maintenance Benefits Of Portable Flow Instruments
    7/16/2018

    Accurate flow measurement is critical for process control and regulatory compliance. Flow meters are essential instruments for water and wastewater facilities, installed at multiple locations throughout entire systems. For the most part, these are permanent installations. However, portable flow instruments prove beneficial in certain situations.

  4. Six Top Factors To Consider When Selecting A Flow Meter

    Water utilities rely on accurate and dependable flow measurement for critical process controls. Regulatory agencies also require flow monitoring and reporting, with specific accuracy limits.

  5. How Calibration Impacts Flow Meter Performance

    Utility managers and operators rely on flow meters to provide critical information for process monitoring and control. They require and fully expect the flow data to be accurate and reproducible.

  6. How To Avoid System Downtime When Installing Flow Meters

    Water and wastewater utilities rely on accurate flow measurement for important process controls. These may include recycle streams, chemical dosing systems, and other operational functions. In addition, regulators require utilities to measure certain flows, such as treatment plant influent and effluent and potable water pumping. Accurate flow measurement is also important for monitoring and reducing unaccounted-for water.

  7. The Challenge Of Flow Disturbances On Meter Accuracy

    Accurately measuring flow is critical for water utility operations. Also, regulatory agencies mandate flow monitoring and require annual calibration of meters. But even a meter in perfect condition and properly calibrated can read inaccurately. Flow disturbances are a common cause of accuracy and repeatability errors.

  8. Sensitive Determination Of Iron In Drinking Water, Mineral Water, Groundwater, And Spring Water Using Rapid Photometric Tests

    The quality of drinking water is regulated by a variety of guidelines, such as the EU Council Directive 98/831,2 and WHO guideline. The key principles used to define these limits consider both health hazards and sensory and technical reasons. Iron, for example, does not exhibit a risk for health in concentrations usually found in drinking water.

  9. The Smarter Water Manager

    Communities around the world are facing a growing storm. Complex challenges including water scarcity, changing demographics, extreme weather patterns, and aging or overly stressed infrastructure are colliding to threaten critical water, energy, transport, enterprise and health networks. The water industry is in the eye of the storm.

  10. In Pursuit Of The Perfect Glass Of Water
    6/12/2018

    Water, classified as one of the basic elements since ancient time, is so essential, so simple, yet can be so challenging to deliver at high quality in high volumes. Pursuing the “perfect” glass of water involves two major influences: 1) regulatory requirements and 2) aesthetics or organoleptic quality (i.e., taste, odor, appearance, etc.). To start, it helps to be blessed with the good fortune of good source water quality, but beyond that it comes down to how a water utility treats and “polishes” the final product. Even for utilities not totally obsessed with garnering national taste-test honors, here are several factors to be considered when searching for the perfect glass of water, and the role that turbidity measurement can play in them.
