Patent ID: 7785674

Claim:
A process of delivering functional compounds to a substrate, the process comprising: introducing an aqueous effluent comprising at least one functional compound through at least one inlet port of an elongate housing of a treatment chamber, the housing comprising longitudinally opposite ends and an interior space, the housing further being generally closed at at least one longitudinal end, and wherein the housing comprises an adsorbent located within the interior space; ultrasonically energizing and electrically charging the adsorbent at a predetermined ultrasonic frequency and electrode potential within the housing using an electrically-charged elongate ultrasonic waveguide assembly, the waveguide assembly comprising an elongate ultrasonic horn; adsorbing the functional compound to the surface of the energized and electrically charged adsorbent to form a carrier component of a delivery system; exhausting the carrier component from at least one outlet port of the housing; and contacting the carrier component with a substrate.
