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.
