A pollution control system for removing particle and gas phase pollutants in a waste airstream exhausted from commercial cooking operations may include a plurality of filters arranged within a housing for filtering particle and gas phase pollutants in the waste airstream. Various ones of the filters may be composed of a variety of different materials, and ozone may be provided within the housing to assist with removal of the pollutants. In some examples, a wash mechanism may be included to wash surfaces of a filter to remove grease therefrom. In some examples, the system may further include means to spray droplets (such as in a fog or mist form) into the waste airstream to condense a portion of gas phase pollutants into condensed particles.

Provided is a solvent separation method and a solvent separation apparatus in which a vaporized solvent is collected at one internal side of a solvent separation unit by attracting the vaporized solvent based on electric field, while the vaporized solvent is prevented from coming into contact with electrodes, and the collected solvent is discharged from the solvent separation unit. Different electric fields are alternately applied to a pair of first electrodes and a pair of second electrodes present at predetermined locations inside a tetragonal tubular solvent separation unit to attract a vaporized solvent toward the second electrodes. Thus, the vaporized solvent is collected in a space between the second electrodes inside the solvent separation unit, and the collected solvent is discharged from the solvent separation unit, together with a portion of the exhaust atmosphere present around the collected solvent.
