BW water reforming device (Trade name :The Biowater)is a product made by industrialization of Japanese traditional technology of water reformation. In old days, natural crystallized minerals were used. But, there are piece to piece variations for natural minerals, and reproducibility which is required for industrial products can’t be maintained. Therefore, we use artificial mineral crystal based on our own recipe of the combination of the ingredients. We use ceramic for base substance, but it is possible to use other substance like metals. Also, guide blades are built in the device in order to obtain better water reformation with water flow.
