WATER PURIFICATION SYSTEM AND PROCESS

A small processor produces potable water from contaminated water. Its components mount in a hermetically sealed housing, which include a boiler-condenser assembly and a compressor. Contaminated water is injected onto one or more aluminum shells inside the boiler-condenser assembly. Shell rotation enhances boiling heat transfer by causing the water to form thin films on the shells' inside surface and also enhances condensing heat transfer by assisting in removing the purified condensate from the shells' outer surface. The change of phase from vapor to liquid transfers through the shells to the boilers to cause boiling. Vapor boiled inside the boiler chambers flows toward the compressor, which raises the vapor's pressure and temperature to drive the process. Shell rotation causes centrifugal force that holds and directs remaining water on the shells' inside walls towards the output pumps. Wipers mounted adjacent each shell's boiler surface smooth contaminated water. Wipers adjacent the condenser ...
