What Is a Dry Scrubber, and How Does It Work?

A dry scrubber, or dry scrubber system, is a type of pollution control equipment that is designed to remove harmful gases and particulates from industrial exhaust streams. Dry scrubbers are primarily used to abate acidic gases, like those associated with acid rain. This is one of the most common pieces of equipment found in manufacturing plants, because of its ability to handle high temperature, highly acidic exhaust streams. A dry scrubber works by combining carefully chosen chemical reagents with the exhaust stream at incredibly high speeds, that react with or absorb the compounds in the stream. These chemicals react differently, depending on which compounds are being targeted; reactions either neutralize the dangerous. Teral-Aerotech’s or absorb them into a different compound all-together. Once converted, the substance left over can then be disposed of or transported easily. Each type of scrubber media removes particles and compounds in a different way; some chemical reactions, while others use electrostatic adhesion.
