UGSI Case Studies

  1. Treatment Plant Upgrade Eases Operations And Increases Safety
    2/22/2018

    Now in operation for well over two years in the Malambo, Colombia, the Microclor® system has proven itself in terms of reliability and safety. According to management, the clear, vertically-oriented cells and the system’s open architecture allow for easy inspection and simplify any minor maintenance that might be required.

  2. Residual Control Technology Saves Millions Of Gallons Of Water While Maintaining Consistent Chloramine Residual Levels
    12/5/2017

    Like many cities within the Dallas-Fort Worth metroplex, the City of Coppell experienced water quality challenges at different periods throughout the year. In particular, the City had difficulty maintaining adequate chloramine residuals at the 1.5 MG Southwestern elevated storage tank during the warmer summer months when outdoor watering was restricted to conserve water.

  3. Treatment Plant Upgrade Includes Conversion To On-Site Sodium Hypochlorite Generation To Ease Operations And Increase Safety
    9/15/2017

    Fairmont, Minnesota, known as the City of Lakes, is located in Martin County in southern Minnesota. The city’s water treatment plant serves a mix of customers including approximately 3,900 residential taps, 500 commercial and 17 industrial customers. Looking to the future, Fairmont city leaders began to investigate upgrading the city’s water treatment plant in 2010. The existing plant had been in operation for well over 70 years and relied on gas chlorine for disinfection.

  4. Automated Residual Boosting System Improves Chloramine Levels, Eliminates Nitrification In 400,000-gal Tank
    7/31/2017

    Like many municipalities in urban and suburban areas, San Bruno’s source water comes both from its own groundwater supply and through a purchase agreement with a major water utility — in this case, San Francisco Public Utilities Commission (SFPUC). And, like many municipalities in California, SFPUC, along with San Bruno, switched from free chlorine to chloramines in 2003 largely to reduce disinfection by-products.

  5. Disinfectant Residual Control System Eliminates Need For Deep Cycling, Breakpoint Chlorination And Improves Pressure Zone Water Quality
    6/27/2017

    Walnut Valley Water District spans a 29 square mile area in semi‐arid southern California about 20 miles east of Los Angeles. Like many water districts planning for growth amid periodic droughts is challenging and compounded by the need to deliver high quality water throughout the district of over 100,000 people and more than 26,000 service connections. Read the full case study to learn how Walnut Valley aggressively pursued operational strategies in their water storage tanks to limit nitrification risk.

  6. 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.

  7. Thermally Homogenous But Chemically Stratified: Active Mixing Achieves Uniform Residual Levels In 5 MG Concrete Tank
    6/22/2017

    Pinellas County, Florida is typical of many major metropolitan water systems, with over 700,000 customers, 2,000 miles of piping and several large water storage facilities.

  8. City Of Punta Gorda Improves Distribution System Residuals By Installing The Tank Shark® Mixing System In Two Million Gallon Punta Gorda Isles Reservoir
    6/14/2017

    Historic Punta Gorda, located on the shores of scenic Charlotte Harbor on the west coast of Florida prides itself in the proactive management of its water supply. With the responsibility of providing water to over 34,000 customers in the 38 square mile service area, Punta Gorda manages 237 miles of distribution pipe and two water storage facilities. The 1 million gallon (MG) Burnt Store elevated tank and the 2 MG Punta Gorda Isles ground storage tank provide distribution system balance as well as the ability to meet peak demands and fire protection capacity.

  9. Polyblend® Mechanical Polymer Activation System Outperforms Hydraulic Polymer Mixing Unit
    6/8/2017

    Henry N. Wochholz Regional Water Recycling Facility (WRWRF) consists of primary, advanced biological secondary and tertiary treatment with advanced total nitrogen removal. Always interested in enhanced treatment performance, the staff members recently examined the polymer use of the existing dewatering belt filter presses. 

  10. Tank Shark® Active Tank Mixing Proven To Be Superior To Dedicated Tank Inlet/Outlet Design
    6/6/2017

    San Jose Water Company (SJWC) provides drinking water for over a million people in the greater San Jose Metropolitan region and is a recognized leader in drinking water treatment and distribution system water quality management. With over 90 water storage facilities in service, planned maintenance and rehabilitation of capital assets is a key component of SJWC’s CIP program.
