| Abstract |
This research program was performed with the overall objectives of obtaining relevant design parameters and capital and operating costs of both adsorption and various aeration techniques for the removal of specific organic contaminants from the City of Glen Cove's drinking water supply. Major contaminants present were trichloroethylene, tetrachloroethylene, cis-1,2-dichloroethylene and 1,1,1-trichloroethane. A pilot plant was constructed and operated for three phases by using water from one of the City's contaminated wells as the influent to several treatment units. The four year pilot plant testing program was completed January 28, 1983. During this period the pilot plant studies evaluated the removal of the contaminants by adsorption using a synthetic resin (Ambersorb XE-340) and several aeration methods including diffused aeration, packed-column diffused aeration, induced-air spray aeration, packed-column induced-air spray aeration, and air-lift pumping. During the third phase, the U.S. EPA delivered, installed and operated a packed-column air-stripping system utilizing induced air. |
