Humic acid and other organic compounds present in eluates from filters used to process large volumes of treated tapwater using the Aquella virus concentrator were found to share certain properties. Both humic acid and the other organic compounds in the filter eluates adsorbed to membrane filters at low pH, were eluted from membrane filters at high pH, interfered with virus adsorption to membrane filters, formed flocs at low pH, and were removed by anion-exchange resins.
