Wastewater Case Studies and Whitepapers

  1. Onsite STEP System Handles Seasonal Peaks At U.S. National Park 4/20/2020

    When it was determined that the septic tanks and drainfields at Stinson Beach were coming to the end of their useful lives, the Golden Gate National Recreation Area looked for a cost-effective replacement that would not be overly noticeable to park visitors.

  2. How AI Optimizes The Chemical Treatment Of Wastewater 11/5/2020

    Wastewater treatment is a complex process that has largely remained unchanged for the last 100 years. Besides the physical and biological processes, the chemical treatment of wastewater is the third and perhaps the most crucial part of sewage processing and wastewater treatment practices. Typical operations include the processing of sewage/effluent through various stages of comprehensive chemical treatment, like pH neutralization, oxidation, ion exchange, coagulation, and flocculation.

  3. Santa Monica, CA Case Study 12/22/2011
    The City of Santa Monica shut down the Charnock well fields in 1996 after finding methyl tertiary-butyl ether (MTBE) and later trichloroethylene (TCE) and 1,1-Dichloroethene (1,1-DCE) in the water.
  4. PFAS Remediation: How To Construct A Temporary Solution For A Forever Chemical 7/27/2022

    This article will discuss considerations for designing a temporary solution for removing per-and polyfluoroalkyl substances (PFAS) from water, including effective technologies and how to select a solutions provider.

  5. Foods - Biochemical Oxygen Demand And Chemical Oxygen Demand 1/25/2016

    A food manufacturer in Washington state had a source of well water contaminated with vegetable and fish oils. A five gallon sample was was sent to Kaselco for testing via our electrocoagulation process.

  6. Reconditioned And Rehabbed Filters Succeed At Large Treatment Plant 6/14/2019

    A large treatment plant includes several treatment processes that contribute to providing quality recycled water pursuant to the state of California Title 22 regulations. Major treatment processes include raw wastewater pumping, preliminary treatment, primary treatment, secondary treatment, tertiary treatment with Parkson DynaSand® filters, and disinfection.

  7. Addressing Fouling Challenges In Water Treatment With RO Membrane 4/18/2018

    Reverse osmosis (RO) membranes are widely used in potable water, wastewater, and industrial applications. However, a major issue in the application of RO membrane technology for desalination and wastewater reclamation is membrane fouling. It limits operating flux, decreases water production, and increases power consumption. Membrane fouling also increases the need for RO plants to perform periodical membrane CIP procedure. These problems decrease process efficiency, increase operation cost, and raise environmental issues related to the CIP solutions disposal.

  8. New Insights Into Waste Lagoon Water Mixing 8/31/2012

    All waste lagoons were first designed and thoughtfully planned considering their locations, soil makeup, and waste reduction processes prior to being implemented.

  9. Precision Accuracy Flow Measurement Through Ultra Mag Implementation 7/20/2022

    Explore why he Hach Ultra Mag is a fan favorite in numerous industries such as municipal water and wastewater, amongst others.

  10. Fox Lake's Wastewater Treatment Plant Retrofit Improves Performance And Increases Capacity 2/1/2021

    The existing aerated grit basin (AGB) grit removal system at Fox Lake, IL, was at the end of its useful life and needed to be replaced. There were two requirements for the replacement: they wanted to retrofit the new equipment in the existing area and to eliminate grit deposition in the grit basin which was very difficult to remove. Steve Vella, Fox Lake’s plant Supervisor, saw the HeadCell® at WEFTEC in Chicago. He liked the stacked tray concept, and thought it would be the ideal solution to their plant’s grit problem. He had seen similar operational principles in lamella systems. The stacked tray design would allow them to increase their surface area which would increase their grit system performance, while staying within the existing area used by the AGB.
