Tokyogawa can remove rust and water scale from water distribution pipes.
This device works by releasing rust from inside the pipes, preventing blockages in water distribution. Tokyogawa can control the electric potential of positive particles around the water surface by electromagnetically modulating at a certain frequency from the outside of the pipe.
