New wet electrostatic precipitator for control of fines
Bionomic Industries
In January, this company launched its new HEI (high-energy ionizer) Wet Electrostatic Precipitator (WESP) system (photo). Said to be a breakthrough in the advancement of state-of-the-art fine-particulate-matter control, the HEI WESP System incorporates a unique discharge electrode technology that can be sized to specific applications, and concentrates a high-intensity ionizing corona in strategic areas within the collecting tubes instead of distributing it along the entire length of the tubes’ treatment area. The resultant particle charging fields are two to three times stronger than conventional precipitators and deliver higher particulate charges, higher migration velocities and a smaller precipitator size for gas capacities from 1,000 through 300,000 actual cubic feet per minute (acfm), says the manufacturer. Unlike other precipitators that utilize sprays, overflow weirs or packed marble beds, the HEI WESP incorporates the Ultimix Conditioning System for gas saturation and collection-tube cleaning and the patented RotaBed Pre-Scrubber for acid removal and particulate-loading reduction. Typical applications include submicron particulate-matter scrubbing, aerosols, mists and smoke removal. — Bionomic Industries, Inc., Mahwah, N.J.
