A hydro-active scrubber and reactor (HSR) system and apparatus is disclosed that includes a main body, an inlet configured to receive a first fluid medium comprised of pollutant particles, and a nozzle configured to dispense a second fluid medium within the main body. In addition, the HSR system and apparatus may also include a cylindrical body or hydro-vortex generator within the main body having a plurality of horizontally positioned rods projecting therefrom, wherein the cylindrical body further comprises a plurality of openings. Further, the HSR system and apparatus can include a motor configured to rotate the cylindrical body thereby directing the first and second fluid mediums through the cylindrical body. In addition, a first area within the main body can receive the pollutant particles from the first fluid medium, and a first outlet within the main body can be configured to direct the received pollutant particles out of the main body.

A system, apparatus, and method are provided for preventing the accumulation of particulate matter such as combustion soot on sensors positioned in exhaust gas conduits of internal combustion engines. In an embodiment, the apparatus includes a device for deflecting soot deposits from sensor surfaces. In an embodiment, the apparatus includes a device employing a surface acoustic wave generator for dislodging soot accumulation or measuring soot accumulations to trigger burn-off events. In an embodiment, an injector injects pressurized bursts of gas toward a sensor surface to dislodge particulate matter. In an embodiment, charged electrodes attract charged particles of soot from the exhaust gas flow to form deposits that are then subject to burn-off events.
