Superior Technology Made Even Better Through Design
 The Bionomic HEI™ Wet Electrostatic Precipitator System represents a major breakthrough in the advancement of state-of-the-art fine particulate control. Centered around precipitator hardware improvements that deliver high reliability and outstanding collection performance, the HEI WESP System incorporates a unique discharge electrode technology that can be sized to specific applications. The system's electrode geometry concentrates a high intensity ionizing corona in strategic areas within the collecting tubes instead of distributing it along the entire length of the tube's treatment area. This high intensity corona provides particle charging fields that are two to three times stronger than those of conventional precipitators–resulting in higher particulate charges, higher migration velocities, and smaller precipitator size.
The Bionomic HEI WESP System also offers the user maximum flexibility through a choice of two innovative, adaptable designs that can meet any application or system layout requirement. Depending upon the particular contaminant properties and gas stream contents, the HEI WESP System can be configured in either a gas upflow or downflow configuration.
Rigid, large diameter mast-supported EZ AlignSM Charging Electrodes add to the simple yet robust construction, and low maintenance of the HEI WESP System. Available UnagonSM Extended Area Collecting Electrode Tubes extend system capabilities with increased efficiency and elimination of tube sheets that need to be cleaned due to sticky or scale forming particulates.
Other key features of the HEI WESP System are the available methods for collection tube cleaning, gas precleaning, and conditioning. Unlike other precipitator designs that utilize sprays, overflow weirs or packed marble beds, the HEI WESP System is the only design that can incorporate the Ultimix™ Conditioning System for gas saturation and collection tube cleaning, and the patented, nonfouling RotaBed™ Pre-Scrubber for acid gas removal and particulate loading reduction.
PLC-based voltage and spark controls to maintain maximum electric field stability, nonfouling insulator locations, and new, improved materials of construction that provide longer life and more resistance to corrosive gases complete the advanced yet economical HEI WESP System.
