CASPERON Solution Brings Process, Operation And Cost Benefits To Michigan Facility
CASPERON Solution Brings Process, Operation And Cost Benefits To Michigan Facility

For 15 years, plans to double the capacity of Michigan’s Zeeland Clean Water Plant remained stalled as the City of Zeeland worked toward a joint wastewater treatment contract with two neighboring Ottawa County communities. As a result, maintaining efficient aeration control posed a challenge for the 1.65 million gallons per day (MGD) facility. When expansion plans moved forward in 2016, the city alleviated those problems with the Xylem Sanitaire CASPERON activated sludge solution process, which eliminated the use of lime to treat waste and significantly reduced the volume of biosolid residuals.

WASTEWATER CASE STUDIES AND WHITEPAPERS

  • ICEAS SBR Technology Enters 30th Year Of High-Quality Effluent Production
    ICEAS SBR Technology Enters 30th Year Of High-Quality Effluent Production

    In the late 1970s, a wastewater treatment plant (WWTP) in Tullahoma, TN, built in 1955, was overloaded and deteriorating.

  • Grit Washer Turns La Crosse’s WWTP Grit Into Green
    Grit Washer Turns La Crosse’s WWTP Grit Into Green

    La Crosse’s WWTP wanted to make some improvements to their treatment processes to make their plant more efficient and effective. Because of the odor, hazardous nature, and sheer weight of the organics-laden grit, La Crosse’s disposal fees were quite significant.

    Emergency Chlorine Scrubber Refurbished After Inspection Reveals Serious Problems

    In December 2006, Integrity Municipal Services (IMS) was contacted by the City of California City Plant Manager Greg Fielding to perform an inspection of their RJ-2000® emergency chlorine vapor scrubber system.

  • Using ATP In Suspended Growth Wastewater Treatment Systems – What Is The Benefit?
    Using ATP In Suspended Growth Wastewater Treatment Systems – What Is The Benefit?

    Suspended growth systems, such as activated sludge, are a very common form of secondary wastewater treatment. The potential to optimize and improve the operation of such treatment plants using ATP is tremendous. ATP can directly quantify active biomass, which is key to providing secondary treatment. Two of the many potential uses for ATP in a wastewater treatment plant are aeration and solids optimization and toxicity monitoring and identification.

  • Advanced Membrane Degassing Technology For Radiation Source Term Reduction And Corrosion Control In Nuclear Power Plants
    Advanced Membrane Degassing Technology For Radiation Source Term Reduction And Corrosion Control In Nuclear Power Plants

    Dissolved gas control in a nuclear power plant’s water system, including the primary make-up water storage tank and refueling water storage tank, can be essential to reduce radiation source term (defined as a release of radioactive material). In particular, controlling dissolved gases can also help reduce the formation of unwanted radionuclides, such as 14C and oxides of 60Co, and alleviate primary water stress corrosion cracking (PWSCC).

    Lime Slakers Restoration In Dallas, TX Leads To Almost $1M Saved Compared To New Systems

    Since opening in 1930, the Bachman Water Treatment Plant in Dallas has increased its processing capacity from 30 million gallons per day to 150 million gallons per day, with the latest upgrade in 2007.

  • Rinse, Repeat: The Rise Of Water Reuse

    I may not be “old school” in the water/wastewater industry, but I have been around long enough to see a number of ideas graduate from sideshow to center stage. In wastewater, the topic in the spotlight at the moment is water reuse — and its role won’t soon diminish. Depending on your part of the world, it will sooner or later be the norm — but the smart ones are planning ahead.

  • Case Study: Steel Processor Wastewater Recycle

    The reuse of industrial wastewater is becoming increasingly common because of water shortages, environmental necessities, economic incentives, government mandates, and societal desires. By David Christophersen, Technical Support Manager, Veolia Water Technologies

    Self-Cleaning Lift Stations And Hydroscreen Drastically Increase Efficiency In Brewery

    ClearBlu provided duplexing in-ground lift stations and a self-cleaning waterfall hydroscreen for the brewery who self-installed the equipment.  ClearBlu design and instructions made it possible for the brewery to install the lift stations and screen themselves, as well as to have the screen stand fabricated locally.  ClearBlu lift stations are fabricated from fiberglass which resists deterioration from acidic wastewater and are self-cleaning.  Round basins can be stirred so that they never have to be cleaned out.

  • The 3 Main Reasons To Use Carbon Dioxide For pH Control
    The 3 Main Reasons To Use Carbon Dioxide For pH Control

    Finding ways to improve everyday processes in more efficient and productive ways is an important goal for most companies. Many water and wastewater treatment facilities use sulfuric acid when pH reduction is needed, but face safety and process risks as a result. As an alternative to sulfuric acid, carbon dioxide (CO2) offers several benefits.

Purge and Trap Background 
When using a concentrator system, it is not essential to understand how it works. However, a good grasp of the fundamentals helps you prevent problems and assists you when you are faced with tasks such as method development and troubleshooting. This section is not intended to be a full theoretical evaluation of purge and trap gas chromatography. The main purpose is to help you develop an understanding of how and why compounds are concentrated.

    Common-Sense Perspectives On Waste Treatment — With A 'Western' Flair

    I have been in the waste treatment business for some years now, and I am continually surprised with what I see promulgated by the people that do this every day and should know better. Out West (Texas, actually), we see life as a more or less continual struggle with all kinds of adversaries. Collectively we call them varmints, and they are ever present as we go about our daily duties. There is much to be learned from folklore in establishing a common-sense perspective, and the convergence of Texan culture and waste treatment technology (and even water treatment) are cases in point.
