Our new concept is to irradiate discharge plasmas to a water film falling
on the internal wall of a pipe. This method enables high-speed, mass water
treatment. A 3D printer is utilized to create optimal reactor shapes. Recent
study has revealed that reactors providing swirl flows of dropping water
show high treatment efficiency.
