ABSTRACT:
A mechanical release system and method for eliminating scale conditions in water are described. The mechanical release system may include a pressure vessel comprising a head that has a through hole extending from an inlet to an outlet on opposite sides of the head, the through hole divided by at least a circumferential partial rib into an inlet section and an outlet section. Implementations may work without restricting water flow or “water-starving” equipment and control water before it enters equipment and create a scale-eliminating environment within water for extended periods of time (e.g., up to six months or more).
