1. New Developments In Thermal Dispersion Mass Flow Meters

    This paper describes a newly developed microprocessor-based thermal dispersion mass flow meter that uses four temperature sensing elements in its flow sensor instead of the traditional two elements and automatically manages changes in gas selection, gas temperature, gas pressure, and outside temperature. By John G. Olin, Ph.D., Founder/Chairman, Sierra Instruments

  2. A Tale Of Two Thermals: Capillary & Immersible

    For gas mass flow measurement and control, Sierra offers the broadest selection of thermal mass flow measurement products on the market. By Mark McMahon, Scientific Product Manager, Scott Rouse, Industrial Product Manager, Sierra Instruments

  3. Math Solutions: Volume Calculations

    Water Online’s “Math Solutions” series, presented by wastewater consultant and trainer Dan Theobald (“Wastewater Dan”), provides an understanding of the sometimes difficult calculations involved in achieving wastewater operator certification.

  4. WEDECO Duron® vs. Medium Brochure

    The WEDECO Duron is head and shoulders above the competition. Medium pressure systems come up short when it comes to energy efficiency, design, system footprint and operation and maintenance costs. The Duron offers the latest in Lo-Hi UV technology that was specifically designed with owners and operators in mind.

  5. Bring On The Bacteria: Conventional Treatment Methods Not Enough To Produce Safe Drinking Water

    Around the world there are guidelines and regulations regarding the quality of drinking water distributed by water treatment plants. These guidelines/regulations are sometimes national, such as U.S. regulations and Canadian guidelines.

  6. Reducing Total Phosphorus In Water Resource Recovery Facilities

    Monitoring phosphate during the wastewater treatment process allows for fine-tuning and optimizing chemical dosing for removal of phosphate, which provides significant cost savings to the plant while protecting the aquatic environment downstream of the facility.

  7. Screentec Pump Station Bar Screen

    Screentec is an automatic vertical bar screen for headworks, pump stations, lift stations, wet wells and manholes. It protects pumps from rags, wipes, plastics and other solids. Screentec prevent pumps from clogging up, extend their life cycle and improve quality of wastewater treatment. Thanks to its vertical bar screen design, it fits into narrow and deep structures, avoiding costly structural changes. Screentec does not have any moving parts under grade level, providing easy and safe maintenance for the operational staff.

  8. Township Success Story With Pump Station Bar Screen

    New Jersey’s Lower Township Municipal Utilities Authority had a problem. The utilities authority operates a 5 MGD plant, with wastewater inflow arriving through a 48-in pipe routed 23 feet below grade level. Their manual inflow pump screening setup was difficult and hazardous to clean, and its 2.5” screen spacing let entirely too much non-dispersible waste through. Their 3,000 GPM non-clog pumps were constantly clogging, and workers were repeatedly exposed to a hazardous situation.
