ABSTRACT:
A water treatment apparatus for use in a post-mix beverage dispenser enables purification of water, removal of water hardness and sterilization of water which is normally accomplished by a precipitation/floculation process used in a bottling plant. This apparatus can treat the water for beverage dispensing purposes and will not require high capital expenditures. The apparatus includes a removable, disposable cartridge having a reactor or first section filled with sand, carbon granules or other heat-conducting material for removing the bicarbonate content and other impurities from the water and a filter or second section having a filter and activated carbon screen for removing solids, traces of chlorine and dissolved organic material from the water. The apparatus also includes heat exchanger coils and a heating element for raising the temperature of the water as well as a holding tank having a gas trap for collecting and removing carbon dioxide and chlorine gas. Various arrangements may also be used in the apparatus to lower the temperature of the water after it has been raised and before it reaches a downstream dispensing portion. An ion-exchange resin may also be included in the second section of the cartridge of the apparatus in order to remove nitrates, sulphates and sodium ions from the water.
