Technology and skills
Modern society is full of toxic substances; we can detect numerous substances that emit toxic gas. We measure the amount of toxic substances in industrial fields and daily life, take countermeasures against it and realize gcreation of comfortable environmenth.
We are a venture company started in Keio University. We have been engaged in research and development of gas capturing and removal method called diffusion scrubber method using diffusion tendency of gas. We developed it based on the research results of the Laboratory of Environmental Chemistry (A research group lead by Prof. Shigeru Tanaka and others). Compared to conventional technology such as chemical filter method and activated carbon method, diffusion scrubber method has the following merits:
-- Handle 10 times more air than the conventional method
-- Running cost is one tenth of those of conventional ones.
-- Removal liquid can be recycled many times when running continuously. (Waste of removal liquid can be significantly reduced.)
-- Lowered removal efficiency can be detected
We believe air filtering by diffusion scrubber method will become a standard in Japan and worldwide in the near future.
We would be glad if we could solve your environmental problem.
