Description:
In preparation of the U.S. Environmental Protection Agency (USEPA) revising the arsenic maximum contaminant level (MCL) in the year 2001, a project was initiated to evaluate the performance of nine, full-scale drinking water treatment plants for arsenic removal. Four of these systems, two activated alumina (AA) plants and two ion exchange (IE) plants, were small systems treating ground water with arsenic concentrations ranging from 20 to 86 ug/L of arsenic. The objective of the project was to determine the arsenic removal capability of the plants over a sustained period of time (6-12 months). This paper describes the general design and operation of the AA and IE plants and presents the arsenic removal results during the monitoring periods.
