Wastewater Contaminant Removal White Papers & Case Studies

  1. Water Works Commission Lowers Risk Profile By Converting To A Safer Disinfectant
    7/24/2018

    Chatsworth Water Works Commission provides both water and wastewater services to the 5,000 residents of the cities of Chatsworth and Eton, GA.

  2. City Of Springfield, MO, Upgrades Disinfection System From Gas Chlorine To On‐Site Sodium Hypochlorite Generation
    7/24/2018

    In April 2013, City Utilities started up three Microclor Model MC‐1500 skid systems, each rated at 1,500 pounds per day of free available chlorine.

  3. Cheyenne Board Of Public Utilities In Cheyenne, Wyoming Successfully Moves From Calcium Hypochlorite Tablets To Microclor® On-Site Hypochlorite Generation
    7/24/2018

    The Cheyenne Board of Public Utilities (BOPU) operates the water and wastewater systems for the capital of Wyoming which has a population of more than 63,000. Located in the fast growing Front Range Urban Corridor, BOPU is challenged by growth, periodic water scarcity and aging infrastructure.

  4. City Of Havre, Montana Successfully Utilizes Mechanical Tank Mixing To Prevent Ice Formation And Improve Water Quality
    7/17/2018

    Located in north-central Montana, the City of Havre is located in a geography that sees summer temperatures over 100°F (38°C) and winter temperatures that can plunge as low as -40°F (-40°C) accompanied by sustained arctic winds of over 20 mph. These dramatic swings in temperature can wreak havoc on disinfectant levels in the summer by creating a “stratified” tank environment conducive to pathogen growth and allow for ice formation in the tank during the winter. Ice formation can lead to tank coating and appurtenance damage as large chunks of ice can suddenly drop from a higher tank elevation and create catastrophic tank damage. The City of Havre realized that adding simple mechanical mixing to their newly refurbished 3.5 MG West Water Tank would solve both the potential summer water quality and winter asset protection issues.

  5. Optimizing Tank Flushing Using A Rapid Decision-Making Framework
    7/5/2018

    In 2017, a municipal water treatment plant was commissioning a new elevated tank. The tank had been cleaned, flushed and disinfected, but initial test results indicated unacceptable water quality. After a second cleaning, the tank was refilled and water samples were sent to the lab for follow-up testing.

  6. Aerobic Treatment Of Wastewater For Fish Flour And Fish Oil Company Reuse
    6/29/2018

    A fish flour and fish oil processing company produces 100 tons of flour a day from fish waste resulting from the broth concentration plant and from drying of flour, washing water, boiler blowdown and cooling towers. The company needed to treat its wastewater and to reduce its water supply costs.

  7. UV Kind Of Town, Chicago Is (Case Study)
    6/22/2018

    The Metropolitan Water Reclamation District of Greater Chicago (MWRD) — of which the Terrence J. O’Brien Water Reclamation Plant (WRP) is part of — has made a number of upgrades to its treatment process in recent years.

  8. 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.

  9. Two Products Combine To Provide An Enhanced Nutrient Removal Advantage To Protect Our Waterways
    3/23/2018

    Cherokee County, GA, conducted an extensive on-site pilot evaluation of several available process options and technologies, including various plate settler designs. Read the full case study to learn how enhanced nutrient removal (ENR) integrated design continues to deliver water quality of <0.1 mg/L Ammonia, <0.07 mg/L Phosphorus and <0.5 NTU. Not only does the WWTP consistently meet EPA direct discharge limits on BOD, Total Nitrogen, Phosphorus and Turbidity, but these final effluent values readily exceed surface water discharge permits levels.

  10. Southern California Water District Reduces Polymer Usage 30% With PolyBlend® Polymer Activation System
    2/28/2018

    Santa Margarita Water District (SMWD), located in southern California’s Orange County, between Los Angeles and San Diego, provides drinking water and wastewater services to over 165,000 residents and businesses. SMWD approached UGSI Solutions about a PolyBlend® Polymer Activation System trial at their 3 A Water Reclamation Plant.
