• Hydrolox Screens: Best Technology Available for 316(b)

    Section 316(b) of the EPA's Clean Water Act requires that the location, design, construction, and capacity of cooling water intake structures reflect the best technology available (BTA) for minimizing adverse environmental impacts - impingement and entrainment.  Under the terms of the rule, Hydrolox traveling water screens qualify as a BTA for minimizing impingement mortality ("modified traveling screens").  Specifically, the EPA noted that Hydrolox screen designs have "shown promise in reducing impingement mortality".

    The final Section 316(b) ruling was published to the Federal Register on August 15, 2014 and became effective on October 14, 2014.

    Equipped with Ristroph-style fish collection buckets, a low-pressure wash, and a fish handling and return system, Hydrolox traveling water screens are a powerful solution for enabling compliance with Section 316(b) of the Clean Water Act:

    • Designed to operate 24/7, year-round
    • Proven to last up to five times longer than traditional chain-driven steel screen systems
    • 40% lighter than comparable steel screens
    • Designed to operate virtually maintenance free
    • Lowest cost of ownership
    • Industry leading 4-year warranty

  • Section 316(b) applies to roughly 1,065 electric power plants, chemical manufacturers and petroleum refiners in the United States that withdraw at least two million gallons of cooling water per day and use at least 25 percent of that water for cooling purposes.  For more information about the EPA's Section 316(b) of the Clean Water Act, visit the the EPA's website.
