Abstract
Abstract A water conditioning apparatus and method wherein raw water is supplied to a plurality of axially aligned stripping chambers to form a cove shaped sheet within said stripping chambers and to cause an aspiration of air in each of the stripping chambers. Alternating high and low pressure zones are formed in the stripping chambers to enhance the air stripping of the water. The water is discharged through an outlet nozzle where the water sprays against the side wall of the nozzle to cause the water droplets to coalesce.
