ABSTRACT:
An aeration system for removing radon and other volatile compounds from a water or other liquid source. Water supplied from a well and/or water pressure/storage tank enters an aeration tank and is sprayed through a clog resistant nozzle. The nozzle creates a cone shaped spray of very fine water droplets or particles. Such spraying exposes the maximum amount of water surface area to the air stream and hence removes about 50% of the existing radon and other volatile compounds contained within the water. The sprayed water is then collected and fills the aeration tank and the collected water is then exposed to a source of high pressure, filtered air which is blown through a conventional sparger to vigorously agitate and aerate the sprayed and collected water in the aeration tank thereby removing any remaining radon and other volatile compounds from the water. The purified water is then re-pressurized and conveyed to the end user facility for use while the radon and other volatile compounds from the water removed from the water are exhausted to the outside environment.
