Wastewater Treatment Case Studies and White Papers

  1. 3M™ Liqui-Cel™ Membrane Contactors Provide An Easy, Flexible Solution For Managing Dissolved Oxygen In Hard Cider
    7/11/2017

    Controlling dissolved oxygen (DO) levels during beverage production is vital for ensuring consistent product quality and shelf life. This is particularly true for canning, where high DO levels can cause breakdown of the can lining, corrosion and even leaking – which in turn can result in product waste and customer dissatisfaction. In some cases, can supplier warranties have exclusions for high DO levels.

  2. Sulzer Pumps Reduce Downtime At Water Utility
    6/26/2015

    Winslow Township — the largest town in Camden County, NJ — sought relief from its clog-prone, unreliable pumps.

  3. Aeration System Prevents Septic Conditions
    1/11/2018

    Circa 2010, Carollo Engineering designed and implemented expansions at wastewater treatment plants in Delano, California and Reedley, California to handle increased flows of up to 8.8 MGD and 5.0 MGD respectively. The proposals for both facilities specified a need for storage and processing of secondary sludge produced by the processes’ secondary clarifiers. Mazzei Injectors were selected to provide an efficient, zero maintenance method of freshening and mixing the sludge. Read the full case study to learn more.

  4. Integration Of Membrana Ultrafiltration And Gas Transfer Membrane Technologies Produces High Quality Water And Controls Corrosion In Cooling Water System
    2/11/2015

    By incorporating Membrana UF and Gas Transfer Membrane (GTM) a resort customer was able to reduce the risk of contaminating its cooling water and protect other system components from corrosion. The compact systems exceeded performance expectations and reduced maintenance and operating costs while maximizing the available space.

  5. Michigan Utility’s New Pumps Underscore Advancements In Wastewater Handling
    3/18/2014

    Ypsilanti’s pumps, originally put into service in 1982, became priority candidates for replacement after operating ten years beyond their expected 20 year service life. The Ypsilanti Community Utilities Authority (YCUA), included the project in the utility’s Master Plan.

  6. Why Municipalities Can’t Afford To Do What They’ve Always Done, Choose Closed Vessel UV
    1/9/2017

    Ultraviolet disinfection is now a standard feature in most wastewater treatment systems. UV has also been embraced by the drinking water community as an effective barrier against chlorine tolerant organisms such as Cryptosporidium and Giardia. The technology is widely favored in wastewater treatment due to its non-chemical nature, the fact that no subsequent dechlorination process is required and its ability to be unselective in disinfection performance.

  7. Case Study: City And County Of Broomfield, CO
    3/31/2011

    The City and County of Broomfield, Colorado, with a population of 48,000 was in need of improved wastewater treatment to meet effluent guidelines for phosphorus, ammonia, nitrates and BOD removal from their wastewater.

  8. Recognized Results Based On Quality Assurance And Quality Control
    5/11/2016

    Responsibility for analysis results lies with the users themselves or their supervisors. Both are therefore liable for any incorrect interpretations and decisions that are made as a consequence of incorrect data.

  9. FGD Purge Treatment In Coal-Fired Power Generation
    3/6/2015

    Stricter environmental policies and regulations worldwide are changing how industry approaches all aspects of business. Likewise, EU (European Union) environmental policies governing air, soil, and water quality have become progressively stringent.

    These policy changes affect the power industry’s balance of meeting growing European energy demands with compliance to environmental standards. In order to conform with EU standards specific for flue gas, a coalfired generation plant (at the time owned by Endesa, Italia, S.p.A.) in Monfalcone, Italy, undertook the measure of installing a state-of-the-art FGD (flue gas desulfurization) system at their facility. This system would remove SO2 (sulfur dioxide) from the emissions for the 336 MW coal-fired power station.

  10. Eco-Focused Winery Reuses Wastewater And Saves Space With TITAN MBR™
    7/30/2019

    Recognized as authorities of bio-dynamic farming techniques and sustainable winemaking in France, family owners of a particular Sonoma County winery sought to utilize eco-friendly practices also in their California vineyards. After purchasing the winery in 2004, the family ownership began overhauling their vineyards and overall winery operation to revitalize every aspect of the winery, from soil to wine making.
