Contacting Power Rule

Through experience, investigators have observed that scrubber efficiency for similar aerosols, regardless of scrubber design, is related to the power consumed by the scrubber in making the liquid-particle contact. Thus, scrubber grade efficiency appears to be a function of power input. Scrubbers are high-energy devices. That is, in general, the higher the energy input per unit volume of gas treated, the more efficient the scrubber is for smaller sized particle collection. Also, higher power inputs imply smaller scrubbing liquid drop sizes and more turbulence.

Semrau (1960) shows that the efficiency of any scrubber for similar aerosols is strongly affected by the power
