Drinking Water Disinfection [Case Studies White Paper]

  1. California Mountain Town Cuts Salt Use, Doubles Disinfection

    The wastewater treatment facility of the remote mountain resort community of Pinecrest Lake bears the brunt of spring runoff and increased summer demands in the area's beautiful surroundings.

  2. EBMUD Successfully Manages Chloramine Residual In 10-Million-Gallon Reservoir With Chloramine Management System

    Located on the eastern side of the San Francisco Bay, the East Bay Municipal Utility District (EBMUD) treats and distributes water to over 1.3 million customers in Alameda and Contra Costa counties. As one of the largest utility districts in California, EBMUD is a leader in the water industry’s water quality, conservation, and sustainability efforts.

  3. Performance Of A Conventional Surface Water Plant Using Mixed-Oxidants For Microflocculation And Final Disinfection

    The surface water source is from snow-melt and summer thunderstorm run-off from the mountains. This water is detained in McClure Reservoir (7876 ft elevation) and Nichols Reservoir (7483 ft elevation) upstream from the CRWTP, a conventional plant built in 1974 with a design capacity of 8 MGD. Because the City has limited surface water rights, and due to decreased demand, the treatment plant usually shuts down for 60 to 90 days during winter. The reservoirs thaw in spring and turn over in autumn, and during the summer rainy season, raw water turbidities may exceed 5 NTU. By MIOX Corporation

  4. San Diego Plant Cuts THM Levels In Half

    The 34 MGD Otay Water Treatment Plant in San Diego, California serves a population of approximately 200,000. It is a conventional treatment plant that uses coagulation, flocculation, sedimentation, filtration and disinfection. The plant receives raw water from two different sources — imported water from the Colorado River and runoff water from three local reservoirs.

  5. Utility Enjoys More Than Seven Years of On‐Site Sodium Hypochlorite Production

    “To me, Microclor® is the top of the line on‐site generation system on the market due to low maintenance and it being very user friendly.” Larry English, Water Quality Manager, Daphne Utilities. Read the full project profile to learn more.

  6. Ozone System Delivers For Miramar Water Treatment Plant Upgrade And Expansion Project

    A combination of growing demand, aging infrastructure and regulatory requirements acted as drivers for a new ozone system at the Miramar Water Treatment Plant in San Diego, CA.

  7. Largest Ozone Facility In North America Meets Regulatory Requirements And Remediates Taste & Odor Problems

    The North Texas Metropolitan Water District began working to add ozone to its four interconnected water treatment facilities which operate as the Wylie Water Treatment Plant (WTP).

  8. Filtration Avoidance in Surface Water - North Tahoe, California (Case Study)

    With its mountain beauty and deep, clear waters, Lake Tahoe is one of the most popular vacation spots in the California/Nevada area.

  9. Taste and Odor Treatment with UV-Oxidation - Mississauga, Ontario (Case Study)

    The Region of Peel is the second-largest Canadian municipality after the city of Toronto, and draws its drinking water from Lake Ontario — the smallest of the five Great Lakes. To meet the projected population increase from 1,160,000 people currently to an estimated 1,571,000 people in 2031, the Region decided to upgrade and expand its water treatment plant. To deal with seasonal taste and odor compounds produced by algae blooms in Lake Ontario, the membrane plant will be equipped with a Trojan UV-Oxidation system.

  10. Dissolved Air Flotation Technology Nearly Doubles Treatment Capacity

    Faced with a tight capital budget, a city in British Columbia required a new design for a water treatment plant capable of a maximum daily water production of 21 MPG during peak demand periods, with an ultimate demand of 29 MGD.
