WATER INDUSTRY FEATURES, INSIGHTS, AND ANALYSIS

  • Beyond The Barriers Of Water Reuse
    Beyond The Barriers Of Water Reuse

    Water reuse may be the moment’s most talked about treatment industry topic. It’s no wonder that as drought persists in regions throughout the world without sign of subsiding, questions about how we can make the most of our water are being asked.

  • Keep Tabs On Your Lift Stations
    Keep Tabs On Your Lift Stations

    Lift stations are so omnipresent in wastewater collection systems that it’s not uncommon for a given utility to maintain hundreds of them.

  • How To Evolve With SCADA
    How To Evolve With SCADA

    Supervisory control and data acquisition (SCADA) systems are the digital pulse of water and wastewater treatment plants. Serving as the information hub, SCADA makes the most of the day’s cutting-edge technology and in turn uses it to make the most of the plant’s operations. But how to keep up with a system that evolves as quickly as the greatest minds in the field will allow?

  • How To Use SCADA To Avoid Overflows
    How To Use SCADA To Avoid Overflows

    If wastewater treatment plant operators have nightmares, it’s a good bet that many of them have to do with sewage overflows. Few events are as catastrophic for a wastewater facility as a surge of water it can’t process being churned out into the public sphere, in violation of environmental regulations, and to the detriment of public health.

  • Does Chlorine Get A Bad Rap?
    Does Chlorine Get A Bad Rap?

    When it comes to disinfection at treatment plants, chlorine has quite the reputation. To some, it’s known as a reliable and trusted solution. To many others, especially among the public at large, it’s looked at with skepticism and concern – but that may be simply a matter of not knowing the facts. Either way, it’s one of the ubiquitous aspects of water and wastewater disinfection… and for good reason.

  • High Purity Water For Pharmaceutical Application
    High Purity Water For Pharmaceutical Application

    Production had shut down because the client’s existing EDI could not meet the water quality requirement. QUA worked swiftly with the OEM to supply FEDI® Rx in two days, enabling them to resume production immediately. QUA was able to do this due to its high quality product and dedicated technical support team.

  • Is Iron In Drinking Water A Public Health Risk?
    Is Iron In Drinking Water A Public Health Risk?

    It’s long been thought that the presence of iron in drinking water is a cosmetic problem rather than a public health concern. But some scientists are now saying that while the iron itself might not be hazardous to your health, what it does to your drinking water is.

  • Carbon Dioxide For pH Control Of Landfill Leachate
    Carbon Dioxide For pH Control Of Landfill Leachate

    A landfill operator’s leachate treatment plant in Missouri required pH reduction following lime-softening and prior to the biological wastewater treatment process. Carbon dioxide (CO2) was chosen as a substitute for sulfuric acid due to improved process control and a reduced tendency to form scale.

Fox Model FT1 Gas Mass Flow Meter Fox Model FT1 Gas Mass Flow Meter

The Fox DDC-Sensor™ is a new state-of-the-art sensor technology used in the Fox Model FT1 Thermal Gas Flow Meter. The DDC-Sensor™, a Direct Digitally Controlled sensor, is unlike other thermal flow sensors available on the market. Instead of using traditional analog circuitry, the DDC-Sensor™ is interfaced directly to the FT1 microprocessor for more speed and programmability. The DDC-Sensor™ accurately responds to changes in process variables (gas flow rate, pressure, and temperature) to determine mass flow rate, totalized flow, and temperature.

Lyso™ Ozone Sludge Reduction Lyso™ Ozone Sludge Reduction

About 40-60% of wastewater treatment cost comes from the handling, treatment and disposal of excess sludge. As more restrictive regulations are put in place and energy costs rise, so does the cost of sludge management and disposal. This is where Praxair can help.

FLT93S FlexSwitch Flow Switch FLT93S FlexSwitch Flow Switch

The FLT93S insertion type FlexSwitch for flow and temperature monitoring represents the first true technological breakthrough in thermal technology in over a decade
