Reciprocating Tray Towers

Reciprocating tray towers can have holes 9/16 in. dia, 50-60% open area, stroke length 0.75 in., 100-150 strokes/min, plate spacing normally 2 in. but in the range 1-6 in. In a 30 in. dia tower, NETS is 20-25 in. and throughput is 2000 gal/(hr)(sqft). Power requirements are much less than of pulsed towers. [Pg.10]
