Cleanable High Efficiency Aerosol Filtration
(CHEAF)

Superior Aerosol Capture for Industrial Processes

Capture difficult-to-control sticky, oily, or liquid aerosol emissions from industrial exhaust gas streams with Cleanable High-Efficiency Aerosol Filtration (CHEAF) systems from Verantis®. CHEAF systems efficiently remove these aerosols with 99.99% or greater removal efficiency, delivering exceptional air quality while extending filter life through continuous cleaning of the filter media.

CHEAF technology captures water-soluble submicron aerosol particulate using a liquid wash system that continuously cleans the filter. These systems are particularly effective for controlling emissions from a wide range of processes, including:

  • Ammonium nitrate and urea prill towers
  • Soda and borosilicate glass furnaces
  • Phosphoric acid mists
  • Phosphorus pentoxide fumes
  • Inorganic chemical calciners and dryers
  • Food product spray dryers
  • Galvanizing fumes
  • Sulfuric acid mists

In addition to soluble aerosols, CHEAF systems effectively manage insoluble particulate matter with mean diameters less than 1 micron, including metallurgical fumes. They offer a cost- and energy-efficient alternative to high-energy scrubbers or mist eliminators that rely solely on Brownian motion.

CHEAF Filtration Device Options:

  • Continuously-cleaned CHEAF: For non-acidic gas streams containing insoluble particulate and liquid or water-soluble emissions in acidic gas streams
  • Renewable media CHEAF: For emissions with both soluble and insoluble particulate matter in acidic or strongly basic gas streams
  • Fixed or candle-type CHEAF: For liquid aerosol control requiring Brownian motion or candle-type mist eliminators

Key Benefits CHEAF Filtration:
