Abstract
Abstract A liquid purification and aeration system including a condenser coil for preheating supply liquid, an external steam heater for superheating the liquid, a centrifugal nozzle for injecting the superheated liquid into a flash chamber surrounding the coil, a baffled overflow tube within the coil for maintaining a predetermined water level, a particulate aeration bed beneath the flash chamber for dispersing the sterile water overflow, and a filtered blower for forcing clean air up through the bed to aerate the fresh sterile water. The superheating pasteurizes the supply liquid to destroy bacterial impurities, the flashing removes and vents entrapped gaseous contaminants, and the aeration further purifies the liquid and oxidizes any remaining impurities.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
46 words
A system as recited in claim 1 wherein the flash chamber and the aeration chamber are cylindrical, the condenser coil is helical, and the means connecting an outlet of the superheating means to the flash chamber comprises a liquid conduit tangentially secured to the flash chamber.
Claim 2
Dependent Claim
63 words
A system as recited in claim 1 wherein the liquid overflow means is positioned within the condenser coil, the means for venting the forced air is positioned within the condenser coil and connected to the liquid overflow means by an anti-siphoning tube, and the baffle surrounds the liquid overflow means and the forced air venting means and extends above the liquid overflow means.
Claim 3
Dependent Claim
63 words
A system as recited in claim 2 wherein the liquid overflow means is positioned within the condenser coil, the means for venting the forced air is positioned within the condenser coil and connected to the liquid overflow means by an anti-siphoning tube, and the baffle surrounds the liquid overflow means and the forced air venting means and extends above the liquid overflow means.
Claim 4
Dependent Claim
35 words
A system as recited in claim 1 wherein the aeration chamber comprises liquid permeable support means adjacent the bottom of the chamber and the dispersing means comprises a particulate bed disposed above the support means.
Claim 5
Dependent Claim
35 words
A system as recited in claim 2 wherein the aeration chamber comprises liquid permeable support means adjacent the bottom of the chamber and the dispersing means comprises a particulate bed disposed above the support means.
Claim 6
Dependent Claim
35 words
A system as recited in claim 3 wherein the aeration chamber comprises liquid permeable support means adjacent the bottom of the chamber and the dispersing means comprises a particulate bed disposed above the support means.
Claim 7
Dependent Claim
35 words
A system as recited in claim 4 wherein the aeration chamber comprises liquid permeable support means adjacent the bottom of the chamber and the dispersing means comprises a particulate bed disposed above the support means.
