The Grander process changes the inner structure of water and returns the water molecules to a highly ordered state, making the water more stable.

The Grander process involves a field effect generated by highly structured water ("information water") developed by Johann Grander. The precise method by which he produces "information water" is a trade secret. The information water passes structural information through its field to other liquids nearby. The water which passes near the information water takes on a new structure (is "revitalized").
