Crossflow vs. Counterflow Air Stripping Costs

by John C. Little, Univ of California, Berkeley, United States,

Document Type: Proceeding Paper

Part of: Environmental Engineering

Abstract:

Crossflow towers offer a potential economic advantage over counterflow towers due to savings in fan power costs as well as material costs. These savings increase as contaminant volatility decreases and as water flowrate increases. The costs for both 2-inch plastic packing types examined (spheres and saddles) are comparable except for low volatility contaminants where the spheres result in lower costs.
