Rise off the WESPs

摘要

Dry Electrostatic Precipitators (ESPs) have long been the weapon of choice for utility and industrial paniculate control needs. But a recent trend has seen more customers, particularly in industry, move toward the installation of wet ESPs for use as a polishing device because of their greater effectiveness in achieving ultra-low fine paniculate emissions, as well the added benefits of removing acid mist and some heavy metals. In the U.S., wet ESPs are becoming an important tool for complying with the industrial boiler MACT rule, enacted in 2013.
