Evaluation and control of air quality/ malodors

Measurement techniques to evaluate air quality and odors, especially using human sense of smell, is studied. In Japan, the use of “olfactory measurement” to assess malodors has been established by legislation, and the purpose of this study is to find the way of its application to comprehensive evaluations of air quality in the environment. 
And, a biological treatment system is being developed for use in removing gaseous organic compounds (VOCs or Volatile Organic Compounds), which are major air pollutants currently, and odorants. This equipment is generally known as “biological deodorization” or “biofiltration,” and our research is focusing on high efficiency of pollutants removal and on fine control of microbial activity and biomass growth to achieve its practical use.
  • Air sample at a spot of roadside is collected. Pollution level of the target air is evaluated using both human noses and instruments.

  • A pilot apparatus of biofiltration system for the preparation of its practical use. Unique structures are equipped in gasflow and filter material (patent has been approved)
