Kiyomaru-Kun

"Kiyomaru-kun" is made from natural volcanic ash ”Shirasu”, so it has less impact on the environment than ordinary flocculants. It is safe and reliable to use at civil engineering sites that has to be environmentally friendly, and sites near rivers and the sea.

"Kiyomaru-kun" is made from natural volcanic ash ”Shirasu”, so it has less impact on the environment than ordinary flocculants. It is safe and reliable to use at civil engineering sites that want to be environmentally friendly, and sites near rivers and the sea.

This is a unit-type turbid water treatment facility that incorporates a powder feeder for "Kiyomaru-kun" and can be transported by truck.

By adding and agitating Kiyomaru-kun with a solution containing colloidal particles, the negative charge of the colloidal particles and the positive charge of Kiyomaru-kun ionically combine, causing the colloidal particles to coagulate.
Compared to general flocculants, Kiyomaru-kun is charged with more positive charges, so it can bond with multiple negative charges in colloidal particles, which increases the flocculating power the flocks difficult to break.
Since the number of condensed colloidal particles increases, large flocs are formed.
Furthermore, since there are still many positive charges that do not contribute to ionic bonding, the negative charges on the colloidal particles are attracted to Kiyomaru-kun, causing a bias in electrification, and the opposite side is charged with positive charges, forming an electric dipole.
Then, without going through Kiyomaru-kun, the colloidal particle that has become an electric dipole and another colloidal particle bond between the ion dipoles, making the flock becomes even larger.
