Our Gravel Bed Filter (GBF) technology was developed from fundamental research at the Massachusetts Institute of Technology (MIT) and has been proven in more than 100 installations worldwide since 1980. Over decades of operation, the GBF has demonstrated exceptional reliability and performance across a wide range of industrial applications.

The GBF operates with a slowly moving bed of gravel positioned between two grounded louvers, through which particulate-laden gases flow horizontally. When high voltage is applied to a central electrode, particles become charged and are efficiently captured on the gravel surface.
