<p>Active acoustic piping (10) that allows treatment of material flowing in is disclosed. An inner pipe (12) has a plurality of transducer elements (14) disposed on its external perimeter. A buffer zone (18) around the transducer elements (14) provides an acoustic impedance mismatch, which concentrates the acoustic energy into the flow material traveling in the inner pipe (12). Processes such as decontamination, flow unclogging, fluid and particulate mixing, particulate size reduction, treatment of wastewater and other fluids, and particulate separation are enabled.</p> |
