Zusammenfassung:	A composition and method for reducing odors and cleaning packing media and other components in a wet air scrubber using nonionic surfactants, amphoteric surfactants, and a source of humic acid. Preferred nonionic surfactants include regular and low foam nonionic surfactants. The source of humic acid is preferably organic peat humus. The treatment composition is added to water in the wet scrubber at a concentration of 50-1000 ppm. The treatment composition is a premixed composition in a single container, making it unnecessary to separately add ingredients to the water. The treatment composition is effective at reducing odors by at least 50% compared to no treatment. The treatment composition is also effective at significantly reducing foam levels, making it unnecessary to add a separate defoamer to the water being treated. The treatment composition does not need to use defoamers, enzymes, oxidizers, chlorine compounds, or strong acids to be effective.
