Wet and Dry ESP technologies operate on the same electrostatic principle and are similar, but many questions arise as to when to use one technology over the other, as well as the advantages and limitations of each technology. Hamon Research Cottrell provides both wet and dry ESP technology for a variety of industries,
including iron and steel. Dry ESPs are used to capture coarse solid particulate matter while wet ESPs capture sub-micron solid particulate matter, condensable particulate, water droplets and acid mist. Where particulate characteristics play a large role in the sizing of dry ESPs, this is not the case with wet ESPs, as they are not prone to resistivity problems such as back corona or re-entrainment. This paper compares the two technologies and when it is recommended to utilize the technologies.
