Wastewater Case Studies and Whitepapers

  1. Town Of Kittery, Maine Relies On Lime Feeders For pH Control For More Than 25 years
    6/26/2017

    The Francis L. Hatch water filtration plant is in the coastal town in York county Maine and has an average capacity of 2.6 MGD. This is a surface water plant that utilizes hydrated or “slaked” lime (calcium hydroxide) to maintain the pH level around 7.0. For over 25 years, the district has used two of the UGSI Chemical Feed model 32‐055 Feeders to mix dry hydrated lime with water to create a lime slurry solution that can then be added to the finished water treatment.

  2. Flow Conditioning Improves Flow Measurement Accuracy And Reduces Plant Cost
    12/15/2017

    If you're planning to expand, upgrade or retrofit your plant in the near future, chances are that you'll be facing a real estate crisis when it comes to finding a place for all your new or upgraded equipment. 

  3. Headworks Bar Screen Just Keeps On Running In Topeka, KS
    3/2/2017

    Headworks International has installations all over the United States and in over 40 other countries.  We are always interested to learn about the community our equipment serves.  One interesting place is Topeka, Kansas.

  4. Breakthrough By Dynamic Approach In Sewage High Technology Project
    9/4/2015

    This is a brief overview of a demonstration study for Advanced Pre-treated Tricking Filter System. Demonstrating the efficiency of “A-PTF” which utilizes existing structures efficiently and reduces energy consumption while ensuring high treated water quality, as an alternative to the conventional activated sludge process.

  5. Predicting WWTP Sludge Production And Power Savings From Facultative Operation Of Aerobic Digesters
    9/4/2014

    The objective of this white paper is the prediction of the wastewater treatment plant (WWTP) sludge production and subsequent power savings realized from operating the aerobic digesters via facultative digestion using technology from ENNIX(6)  INC. Development of the predictive spreadsheet permits one to demonstrate the power savings to potential users of the facultative digestion(6) technology.

  6. Waste Lagoon Rehabilitation A New Look At An Old Problem
    9/19/2011

    Throughout the last half-century the municipal and industrial wastewater treatment industry has depended heavily upon the use of waste lagoons in order to provide relatively clean water that could be returned to the environment. These are often called stabilization lagoons. By Jim Dartez, RELIANT Water Technologies

  7. Savings Helps MABRs Gain Traction In Municipalities
    5/9/2018

    An MABR is essentially a biological wastewater treatment process that utilizes seemingly passive aeration through oxygen-permeable membranes. Oxygen transfer through the MABR membranes is diffusion based: driven by concentration differences such that oxygen passes from air at atmospheric pressure into water at a higher hydrostatic pressure. This oxygen transfer mechanism, wherein air is supplied to the process at very low pressure, is the reason MABRs have significantly lower energy consumption compared to other wastewater treatment processes, such as conventional activated sludge (CAS), that utilize diffusers. This energy savings is one of the key reasons MABRs are gaining traction in the municipal wastewater industry.

  8. Luxury Resort Chooses AdvanTex® For Its Low Life-Cycle Costs
    5/1/2018

    A new luxury resort was planned for a scenic location just outside the small Greek village of Paliouri. With no municipal sewer available, the investors needed a decentralized wastewater treatment system. The system would have to consistently meet discharge limits, allow for future expansion, and offer low life-cycle costs. Also, it would need to operate with minimal odor or sound, so as to go unnoticed by guests.

  9. Natural Gas-Fired Combined Cycle Power Plant Improves The Performance Of Water Treatment System
    7/19/2016

    A natural gas-fired combined cycle power generation facility located in Idaho contacted QUA to find a solution to improve the performance of a water treatment system used to recycle the plant’s cooling tower blow down water.

  10. How To Improve Biogas Generation In The Food And Beverage Industry
    6/13/2008

    Anaerobic wastewater treatment processes have been increasing in popularity across the food and beverage industry. Anaerobic processes effectively treat both the normal industrial wastes (higher concentration than municipal wastes) and the very high-strength/low-volume wastes generated by the industry. A welcome side benefit is the generation of biogas for energy production. A food and beverage company can save money, improve sustainability, and lower its carbon footprint. Other drivers include potential legislation in some states to reduce organic waste in landfills and the significant reduction in land application process viability.
