Bionomic Industries’ Series 9000 Preformed Spray Scrubber

Fire Department’s Training Center Optimizes Cost Savings and Reduces Smoke and Odor Emissions with Bionomic Industries’ Series 9000 Preformed Scrubber

A flashover simulator manufacturer investigated the available smoke emission control technologies to incorporate into an upgrade of a major New York fire department’s flashover simulator. After evaluating market offerings, the company determined that Bionomic Industries’ Series 9000 Preformed Spray Scrubber provided the optimal solution.

The fire department’s training center uses the flashover simulator to train over 4,000 firefighters annually. Wood fires are ignited in the unit three to four times per day creating heavy, highly visible smoke.  According to a Battalion Chief, one of the critical requirements of an upgraded simulator was that it significantly reduce smoke and odor emissions.

After evaluating available scrubbing and other technological solutions, the flashover manufacturer determined that the Series 9000 Preformed Scrubber would not only reduce smoke and odor emissions, but also provide the most economical solution. The Series 9000 represents a major advancement in cyclonic scrubber technology and is capable of out performing venturi scrubbers on an energy cost basis for collection of condensable tars with smoke particulate. The scrubber, which uses once-through, mechanically atomized water and a venturi action, virtually eliminates visible smoke. This cost effective solution is one-third the cost of electrostatic precipitators and half the cost of after burner solutions.

Visible smoke emission is virtually eliminated when the Series 9000 Preformed Scrubber is operating.


The Series 9000 has a unique specially designed gas entrance involute section filled with proprietary reverse jet sprays for concentrated and rapid treatment of particles and fumes. he addition of an involute section access panel improved the ability to service the spray components from the exterior of the scrubber, to reduce maintanence and resulting downtime that conventional spray scrubber devices require, while providing a major increase in collection efficiency.

The completely unobstructed open design of the scrubber vessel reduces buildup of sticky condensed tars and smoke particles on the vessel walls. In addition, another access panel was installed to aid in cleaning the side walls when offline. The elimination of internal packing elements, turning vanes or mist eliminator components common to other designs, has substantially reduced manual cleaning frequency.  With its compact size, it can easily be installed in locations with height limit restrictions.

The installation of the new flashover simulator with the Series 9000 has enabled the fire department’s training center to reduce smoke and odor emissions significantly.

Inside the Series 9000 Performed Spray Scrubber

  1. Contaminated gas enters the long narrow involute.
  2. Gas is horizontally accelerated through a concentrated zone of sheared reverse jet spray.
  3. In this zone, the hydraulically atomized extremely fine droplets of scrubbing liquid at high relative velocity collide with the oncoming gas and impinge with the particulate. Any gaseous pollutants present are absorbed or condensed by the millions of created spray droplets. This combination of the unique involute and spray zone design generates a fierce scrubbing action that eliminates bypass and escape of untreated contaminants. The particulate contained liquid droplets agglomerate in the final section of the involute.
  4. It undergoes an initial separation from the gas stream before entering the cyclonic entrainment removal section. Without the need for internal baffles, plates or vanes the high efficiency involute design creates a positive centrifugal action to remove the majority of droplets from the gas. The gas then enters into the cyclonic separator section.
  5. The spinning forces the remaining entrained liquid droplets with pollutants to separate from the gas through impaction and collection on the scrubber interior wall, gravity draining into the sump section.
  6. The cleaned gas free of moisture droplets exits the top of the unit.
