Wastewater Treatment Case Studies and White Papers

  1. WirelessHART® Networks: 7 Myths That Cloud Their Consideration For Process Control Measurement Made Easy

    Misinformation about WirelessHART networks prevails among many instrument engineers in the process industries. This article attempts to set the record straight by debunking seven myths about these networks.

  2. ATP And DNA – Who’s On First?

    As some of you may have heard, LuminUltra has partnered with Microbe Detectives to offer DNA testing services to the drinking water and wastewater industries. So “Who’s on First?” (pun intended); simply put, the partnership’s combined technologies tell you who is in a given water or wastewater sample, and how much is in that sample.

  3. Point Versus Continuous Level Measuring Technologies

    While point level measuring approaches are regarded as simple and user friendly, they lack the capabilities of more sophisticated continuous measuring instruments.

  4. Contact Lens Becomes Latest Pollutant In Wastewater

    The latest disposable causing a stir in the wastewater treatment world is the contact lens. Researchers from Arizona State University recently presented their findings at an American Chemical Society event showing that contact lenses flushed down the toilet or washed down the drain can pass through wastewater treatment plants and accumulate in sewage sludge. As sludge is often applied on land for disposal and fertilizing, macro- and microplastics from lenses enter terrestrial ecosystems.

  5. Instrumental Solutions For Better Process And Data Management

    Generating accurate data is essential for maintaining water treatment plant (WTP) process efficiency and regulatory compliance. Here are multiple considerations for automating critical instrument monitoring and management activities that can help generate reliable data as a means of supporting timely decision-making, accurate compliance, and maximum confidence in WTP performance.

  6. Fast-Tracked Arsenic Project For Food Processing Plant

    AdEdge Water Technologies was recently engaged by Pharmaceutical Services & Installations (PSI) to provide a treatment option for the Century Packaging Corporation in Las Piedras, Puerto Rico.

  7. 31% Energy Savings For Skanderborg Waste Water Treatment Plant With New 55 kW Atlas Copco ZS Blower

    With a savings goal set at 25 % for the Danish waste water industry, optimizing all parts of the operation, so even the aeration, is of the highest importance. In 2011, The Skanderborg Waste Water Treatment Plant replaced one of its 75 kW lobe blowers with a new 55 kW Atlas Copco ZS screw blower and were able to reduce their energy consumption with 31%.

  8. Case Study: Online Colorimetric System For The Chemical Phosphate Precipitation Process Optimization

    To optimize the chemical dosage to precipitate phosphates from waste- water, an orthophosphate ion analyzer is used, equipped with a reliable sampling system. By Endress+Hauser, Inc.

  9. Pumping Solution Gives Rolling Foothills Communities A Foothold On Wastewater Efficiency

    Beaver Falls, Pennsylvania, characterized by the rolling foothills of the Appalachian Mountains, is located in Western Pennsylvania, northwest of the City of Pittsburgh. By The Gorman-Rupp Company

  10. Meeting New Effluent Quality Requirements With MBRs

    When the California Regional Water Quality Control Board (RWQCB) issued a new waste discharge requirement, the Nevada County Sanitary District saw that a major upgrade of the existing WWTP's lagoon system would be required. An MBR system was selected due to its capability of meeting new effluent quality using the existing plant footprint and its competitive operating costs.
