Core Technology

Our technology is centered at foamed porous glass “Porous Alpha” from glass and shell as core technology, developing its application

Core technology and some of applications are patented in Japan

Our solutions based on our technology applications
Water treatment: Adsorption & desorption of fluorine
Water treatment: Adsorption & desorption of Phosphorus ion

Porous Alpha is made by burning of mixture of pulverized glass and shells

Porous Alpha is a soda-lime glass composed mainly of silicon dioxide (silica), calcium oxide and sodium oxide
