Quick Summary

A spray-tower scrubber is a type of wet scrubber used for air pollution control. In this technology, an upward-flowing airstream is sprayed with water or another liquid from nozzles. The liquid washes particulates out of the air as they collide with the water droplets. Spray-tower scrubbers can effectively remove about 90 percent of particulates larger than 8 micrometers. This method is also used for gas absorption, where a liquid absorbent captures gaseous pollutants from the air.12

Scrubbers
In a spray-tower scrubber, an upward-flowing airstream is washed by water sprayed downward from a series of nozzles. The water is recirculated after it is sufficiently cleaned to prevent clogging of the nozzles. Spray-tower scrubbers can remove 90 percent of particulates larger than about 8 μm.
