    The challenge for Sulzer was to prove that the new products are even better than the reliable and proven components previously used in two aeration basins of the new Pulawy wastewater treatment plant in Poland.

  2. Ceramic Membranes Offer High Performance, Long Life, And Lower Operating Costs For Water Treatment
    7/23/2018

    Microfiltration and ultrafiltration have become mainstays in the water treatment arena. These processes remove contaminants from water by passing it through a low-pressure membrane. Membrane filters are constructed with a variety of materials with various pore sizes. The challenge is determining which best suits the application with regard to performance, cost, and ease of operation.

  3. Smart Water: Remote Sensing
    7/19/2018

    Automated metering systems (AMSs) or “smart meters” can provide valuable data for electric and water utilities. Data analytics can be used to improve customer service, boost conservation, monitor the system, and even forecast demand. An ultimate goal might be to eventually monitor everything from streetlight intensity to fire hydrants.

  4. City Of Havre, Montana Successfully Utilizes Mechanical Tank Mixing To Prevent Ice Formation And Improve Water Quality
    7/17/2018

    Located in north-central Montana, the City of Havre is located in a geography that sees summer temperatures over 100°F (38°C) and winter temperatures that can plunge as low as -40°F (-40°C) accompanied by sustained arctic winds of over 20 mph. These dramatic swings in temperature can wreak havoc on disinfectant levels in the summer by creating a “stratified” tank environment conducive to pathogen growth and allow for ice formation in the tank during the winter. Ice formation can lead to tank coating and appurtenance damage as large chunks of ice can suddenly drop from a higher tank elevation and create catastrophic tank damage. The City of Havre realized that adding simple mechanical mixing to their newly refurbished 3.5 MG West Water Tank would solve both the potential summer water quality and winter asset protection issues.

  5. 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.

  6. Instrument Resiliency For Tough Times
    7/17/2018

    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.

  7. 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.

  8. California — A State Ready And Willing To Embrace Recycled Water
    7/13/2018

    Water has never been more in demand, and innovative approaches to improving water security have never been more imperative. As our global population grows exponentially, cities and towns expand to accommodate new inhabitants, providing the resources and services they need. Rapid agricultural and industrial development continues apace.

  9. Internet Of Water To Tackle Growing Water Risks
    7/13/2018

    Flanders pioneers the internet of Water, a unique intelligent water management system based on a network of connected sensors, that enables a permanent and real time follow-up of water quality and water quantity. This internet of Water will enable Flanders to tackle the growing threat of water inconvenience, water scarcity and water pollution.

  10. Six Top Factors To Consider When Selecting A Flow Meter
    7/13/2018

    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.
