A method for removing noxious, hazardous, toxic, mutagenic, and/or carcinogenic compounds and/or precursor compounds from a comingled gas, liquid, and/or solid stream is described. In one embodiment, the method is used to prepare the stream for feeding to an oxidizer, such as a thermal oxidizer, to reduce the amount of particulate matter discharged by the oxidizer and includes passing the stream through an ambient or chilled temperature condenser followed by an optional gas/solid separator, and one or more gas scrubbers prior to feeding to the oxidizer.

A ventilation system configured to be self-cleaning, wherein said ventilation system includes: a filtration unit configured to filter exhaust air led through it by at least one air duct; a condensation chamber configured to collect condensation water from the exhaust air; a heating element configured to heat the condensation water to a temperature equal to or above 65 degrees Celsius; and a sprinkler system configured to sprinkle the condensation water in one or more of the filtration unit, at least one of the at least one air duct, and/or the condensation chamber, wherein the ventilation system is thus configured to provide a self-cleaning of the ventilation system utilizing the condensation water.
