ABSTRACT:
Water containing scale forming materials is passed in a tortious path into contact with a series of alternating positively and negatively charged grids, causing scale to be selectively deposited on the grids. The grids are vibrated periodically to break up the scale into fine particles, which do not redissolve or form scale elsewhere.
