Abstract:
A method of purifying a batch of liquid with ozone wherein the batch of liquid is released from a storage container and is mixed with an ozone-containing gas produced from a generator to form a liquid/ozone mixture, wherein the mixture is conveyed through a passageway to produce a purified batch of liquid that can flow out of the purifier through a dispenser, the method comprising:a. after mixing the ozone-containing gas with liquid flow commencing at the beginning of the batch purification cycle, directing the liquid and ozone mixture in an upflow chamber in which an initial flow of liquid rises as bubbles of ozone-containing gas rise at a faster rate to overtake the preceding liquid so that a leading volume of liquid flow is contacted with ozone early in its advance through the passageway; andb. blocking entry of untreated liquid into the passageway except when the purifier is purifying liquid flow.
