Abstract
An air stripper assembly includes a housing having at least one sieve tray operatively positioned therein. Each sieve tray is selectively removable from the housing. If more than one sieve tray is positioned within the housing, each is removable without a need to change orientation of any other sieve tray positioned within the housing. Thus, an operator can easily clean and maintain a selected sieve tray, without disassembling the entire assembly or affecting the location of other sieve trays.
