Wastewater Disinfection WHITE PAPERS

  1. UV Disinfection Upgrade For Water Reuse - EWA Beach, Hawaii (Case Study)
    3/15/2017

    The Honouliuli Water Recycling Facility (WRF) includes filtration and UV disinfection to treat to Class R-1 reuse standards for various uses, including irrigation. In order to maintain high-level reuse, simplify maintenance, and reduce operation costs, the Honolulu Board of Water Supply decided to replace its 15-year-old TrojanUV4000™ with a TrojanUVSigna™.  With the high cost of power in Hawaii, this system upgrade will provide significant power savings (estimated at 75%) and will enable equipment payback in less than 2.5 years.

  2. Florida County Partners With The WateReuse Association To Find The Best Use For Reclaimed Drinking Water
    2/14/2017

    In 2016 Hillsborough County Public Utilities, a forward thinking organization, initiated the first direct potable reuse pilot project in Florida. In its efforts to utilize 100 percent of its reclaimed water, the progressive utility created a successful program to effectively suspend surface water discharges.

  3. Safe, Energy Efficient Disinfection For 45 MGD Combined Sewer WWTP Improves Water Quality
    2/14/2017

    The Hudson River, in the Capital District of Albany, NY, is a popular recreational area for boating, swimming and fishing. Unfortunately combined sewer overflows following storm events and snow melt from sewer systems dating back to the 1800’s were causing increased fecal coliform counts which in turn resulted in health alerts and limited access to the river. After considering several alternatives, the Albany County Sewer District selected a Wedeco Duron 60i2-2.5X4, with high power Ecoray 600W lamps, for their disinfection system.

  4. Project Profile: WWTP Dundee, Oregon Earns An Incentive By Reducing Energy Consumption With The Help Of ETS-UV™ Disinfection Systems
    2/3/2017

    The City of Dundee is a growing community with a strong economy boasting three wineries within the city limits and several others in the surrounding Willamette River Valley. The City’s existing WWTP was nearing capacity, and the limited discharge to the Williamette River would not adequately support Dundee’s planned growth.

  5. The World’s Largest Drinking Water Plant Using Ozone Serves 1.6 Million Customers
    1/20/2017

    Facing new limits on acceptable levels of DBPs in the drinking water, as well as age-old complaints about the taste of the water during the summer algal bloom, the North Texas Municipal Water District turned to ozone disinfection as a possible alternative able to address both concerns.

  6. Indirect Potable Reuse With UV-Oxidation - Big Spring, Texas (Case Study)
    12/12/2016

    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.

  7. Emergency Chlorine Scrubber Restoration Saves County Of Maui Over $100,000
    11/18/2016

    Read the full case study to learn how the County of Maui Department of Water and IMS determined that spent caustic used at the local wastewater treatment plant and the acid wash solution generated during the cleaning process could be neutralized on-site and disposed through the local wastewater treatment system.

  8. Emergency Chlorine Scrubber Refurbished After Inspection Reveals Serious Problems
    11/18/2016

    In December 2006, Integrity Municipal Services (IMS) was contacted by the City of California City Plant Manager Greg Fielding to perform an inspection of their RJ-2000® emergency chlorine vapor scrubber system.

  9. Removing 12” Of Caustic Build-up Returns Chlorine Scrubber To Optimal Performance for Oglala Sioux Rural Water
    11/18/2016

    The MNI Wiconi Water Treatment Plant in Ft. Pierre, SD was built for the Oglala Sioux Rural Water Supply System between 1997 and 2002 with a grant provided by the U.S. Department of Interior.

  10. Chlorine Scrubber Installation Protects World-Class Water Treatment Plants In The Phillipines
    11/18/2016

    In 2014, bids were solicited to design, supply, install, and commission two Emergency Chlorine Scrubber Systems at the La Mesa Treatment Plants 1 and 2 in Quezon City, Philippines.
