ABSTRACT
This chapter discusses the theory of countercurrent packed tower aeration. It presents all the aeration methods can be applied for the removal of radon. Aeration in water treatment is the process of bringing air into intimate contact with the water for the purpose of exchanging gases between the two phases. Fouling of the packing media is one of the major operational problems affecting the performance of the packed tower aeration (PTA) process. The quality of the water to be treated influences the degree and severity of fouling of the media. Air stripping of volatile organic compounds with microporous polypropylene hollow-fiber membranes has been introduced as an alternative method to PTA, with advantages over PTA in both size and operation. The principal volatile odorous compound in many groundwaters is hydrogen sulfide gas, which imparts a characteristic rotten egg smell. The spray jet aeration system is a high-intensity end-of-line aerator.
