ABSTRACT:
A water and energy recovery process for an ice rink is disclosed. The process includes softening and carbon filtering water for use as flood water on an ice rink. The water is then demineralized by reverse osmosis to produce flood water having a specific conductance of about 2 to 30 micromhos/cm. The demineralized water is heated to 90.degree. F. and utilized in a resurfacer to flood the surface of the ice rink. The ice shavings removed from the surface of the ice by the resurface are deposited into a holding means and melted by utilizing recovered heat from the ice rink's refrigeration unit. The melted water from the holding means is used as a coolant in the ice rink's refrigeration unit. The steps of the process are then repeated, utilizing the warmed water from the refrigeration unit.
