Contaminant Removal Case Studies and White Papers

  1. Moving Forward For America's Drinking Water

    Our nation’s record of progress in advancing public health under the Safe Drinking Water Act is significant.

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

    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.

  3. Chlorine Gas Replaced By Dry Calcium Hypochlorite System In New York Suburb

    Town of Greenburgh Consolidated Water District No. 1, serving Greenburgh in Westchester County, west of New York, serves approximately 39,993 people via 11,500 service connections, pumping seven million gallons per day on average.

  4. Ozone To Enhance Removal Of Iron And Manganese And Reduction Of THM

    The U.S. EPA's promulgation of the Stage 2 Disinfection By-Products Rule required  the Public Works Department of Danvers, MA, to establish a Two-Phase upgrade of the plant’s treatment process in order to comply.

  5. Improving The Quality Of Tertiary Effluent For Indirect Potable Reuse With Geographic Constraints

    The Mazzei Sidestream Venturi Injection – Pipeline Flash Reactor System provides a feasible alternative for dissolution of ozone at the Clark County Water Reclamation District (CCWRD) in Las Vegas, because it allowed for flexibility in basin design to meet geographic site constraints.

  6. Clarification And Filtration Upgrades Using ACTIFLO Technology

    The City of Somersworth has a historical background dating back to the early 1900s when it became the first community to start using chlorine to disinfect it’s drinking water.

  7. Indirect Potable Reuse With UV-Oxidation - Big Spring, Texas (Case Study)

    In an effort to reduce reliance on dwindling surface and groundwater supplies in Texas, the Colorado River Municipal Water District (CRMWD) constructed a new Raw Water Production Facility (RWPF) in Big Spring. Big Spring is a 27,000-member community located in West Texas approximately 300 miles west of Dallas. This RWPF treats secondary wastewater to a standard that allows it to be re-introduced directly into the raw water supply for the water treatment plants of Big Spring, Odessa, and other communities in the region.

  8. Project Profile: Berea, Ohio Detects Cryptosporidium In Source Water, Installs ETS-UV™ Systems For Protection

    First settled in 1836, the City of Berea, Ohio gained acclaim as being the source for dimensioned stone formed from locally quarried sandstone, notably grindstones. The grindstones were shipped to Cleveland by oxcart and, as demand grew, later by a purpose-built railroad to the Big Four Railroad across the Midwest. Now many of the former quarry pits are better known as Baldwin Lake, Wallace Lake and Coe Lake.

  9. Tank Shark® Active Tank Mixing Proven To Be Superior To Dedicated Tank Inlet/Outlet Design

    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.

  10. Mitigating Environmental Impact Of Gold Mine’s Wastewater Through Ozone Oxidation And Aquifer Re-injection

    Installing and operating an ozone oxidation system for wastewater remediation at a gold mine located in a remote region of Alaska is full of challenges.
