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.

A water treatment apparatus for use in a post-mix beverage dispenser comprising: cartridge means for housing at least first and second sections, said first section having at least an annular portion which defines a central aperture therein, said annular portion containing a heat-conducting material, said second section containing at least a filter portion and an activated carbon screen; water input means for introducing water into said first section; heating means for increasing temperature of water introduced into said first section, said heating means being insertable into said central aperture of said first section, said increased temperature of said water causing bicarbonates contained in said water to decompose and to be precipitated and deposited onto said heat-conducting material contained in said first section; water storage means for receiving water from said first section of said cartridge means after the temperature of said water has been raised; gas collection means located in said water storage means for trapping gas produced in said first section and gas produced from said water in said storage means, said collection means preventing said gas from being redissolved into said water in order to aid purification of said water; means for removing said water from the water storage means and for introducing said water to said second section of said cartridge means, said second section thereafter removing impurities from said water in order to further purify said water; means for discharging said water from said second section and for permitting said water to move to a dispensing portion of said post-mix beverage dispenser.
