. A pilot‐scale test confirmed that malodorous air containing 600 mg l −1 ammonia can be passed through a soil filter with 98.5% removal efficiency. Furthermore, the concentrations of methyl mercaptan, dimethyl sulfide, dimethyl disulfide, actaldehyde, and trimethyl amine were also significantly reduced using soil as a filter. The tests provide technical information for planning of industrial‐scale soil filters: linear velocity, bed depth, properties of soil, reliability, and effects of soil deodorization on various types of odorous substances. It is concluded that the soil can be an effective filter to remove noxious and malodorous gases derived from industrial processes.
