This invention relates to a process for reducing odor perceived by a nearby community from an odor-emitting system, e.g., sewage treatment, etc., by adsorbing on core particles, as described, condensible components present in the system. The malodorous components then cannot adsorb in a film of condensible components on the aerosol to be carried by the aerosol plume into the surrounding community, but remain with the humid gas plume to be dispersed upward into the atmosphere. The process is useful for any system which contains condensible components and malodorous components and whose emissions form aerosols.

A process for substantially reducing the odor perceived by the community of an aerosol plume emitted from an odor-emitting system, the system having malodorous, low-boiling, hydrophobic components and relatively nonmalodorous, high-boiling, condensible, hydrophobic components, and water, the process
A process for substantially reducing the odor perceived by the community of an aerosol plume emitted from an odor-emitting system, the system having malodorous, low-boiling, hydrophobic components and relatively nonmalodorous, high-boiling, condensible, hydrophobic components, and water, the process comprising (a) contacting the relatively nonmalodorous, high-boiling, condensible, hydrophobic components of the water-containing odor-emitting system with effective amounts of water insoluble core particles reactive with or adsorptive to the relatively nonmalodorous, high-boiling, condensible, hydrophobic components, said particles having substantially all their surfaces exposed on the exterior of the particles, whereby the relatively nonmalodorous, high-boiling, condensible, hydrophobic components react with or are adsorbed to the core particles forming a coating thereon, thus substantially preventing the formation on the aerosol of a film of the relatively nonmalodorous, high-boiling, condensible, hydrophobic components which would entrap the malodorous, low-boiling, hydrophobic components on said aerosol, (b) preventing the relatively nonmalodorous, high-boiling, condensible, hydrophobic components from being carried into the community with said aerosol plume, and (c) dispersing residual malodorous, low-boiling, hydrophobic components into the atmosphere.
