Method for water degasification and distillation

A method for producing a distilled water product that is at least partially aerated which comprises providing a distillation apparatus including a water reservoir container having a water inlet and outlet thereto connected so as to create a reservoir of water therein and a boiler smaller than the reservoir container with an open connection between container and boiler for water flow to or from the boiler, a steam line overhead of the water level in the boiler leading to a condenser immersed in the reservoir and an outlet from said condenser for discharge of condensate, the distillation apparatus further including a filter at the outlet of said condenser for filtering the condensate and for sterilizing and filtering any air entering said filter through reverse flow, and a mechanically operated stirrer in the reservoir to cause swirling in the reservoir water and generation of steam bubbles therein;

• maintaining a predetermined level of reservoir water by introducing feed water into and removing water from said container at a flow rate which maintains a temperature in the range of about 180.degree.-190.degree. F. in the reservoir and heating the water in said boiler to generate steam, the steam passing into said condenser to be condensed therein by heat exchange against the reservoir water whereby the reservoir water becomes heated while at the same time mechanically stirring the water of said reservoir so as to cause generation of steam bubbles in the reservoir water whereby the heated reservoir water becomes devolatilized and deaerated prior to entering said boiler, and passing air into said filter whereby devolatilized water converted into steam in said boiler and thereafter condensed in said condenser to become the distilled water product absorbs filtered and sterilized air during passage through the condenser and through the filter.
