  • Lead exposure assessment device
    Patent number: 10968113
    Abstract: The invention relates to a device and method to quantify the lead exposure of an aqueous feed to humans, remove lead from the aqueous feed, and identify the presence of lead service lines. The device includes an inlet to receive a lead-containing aqueous feed; an outlet to discharge a lead-depleted treated aqueous feed; and at least one cartridge containing sampling media positioned so that the lead-containing aqueous feed passes from the inlet and through the cartridge to produce the lead-depleted treated aqueous feed for discharge through the outlet.
    Type: Grant
    Filed: September 7, 2018
    Date of Patent: April 6, 2021
    Assignee: GOVERNMENT OF THE UNITED STATES AS REPRESENTED BY THE ADMINISTRATOR OF THE U.S. ENVIRONMENTAL PROTECTION AGENCY

  • Biological filter for oxidizing ammonia in drinking water treatment
    Patent number: 8029674
    Abstract: A process for treatment of water to convert ammonia to nitrate including: feeding water containing dissolved ammonia, as an influent introducing water to be treated, into a packed column containing filter media as packing; introducing air through a diffuser at the bottom of the packed column to maintain the water saturated with oxygen throughout the packed column; establishing colonies of bacteria converting ammonia to nitrate within the column; and removing an ammonia-free and nitrite-fee effluent from the column.
