A 3000 cfm continuous regenerable ChemBio Mitigation system has been tested at the Anniston Immune Room facility. The regenerable system permits lower sorbent inventory and lower pressure drop. The thin layered media can be designed to meet specific broad spectrum threats at 5-Log removal. Regeneration is key to reducing weight, volume and power requirements resulting in advantages in total cost of ownership over throw away units.
The system consists of a COTS electrostatic precipitator (ESP) with TiO2 coated collection plates for photocatalytic oxidation (PCO) of collected biomass. The ESP filters the majority of the particles entering the system protecting the following components. An open chamber with germicidal UV illumination bulbs follows the ESP/PCO. A COTS electrostatic filter (ESF) with TiO2 impregnated collector/filter meshes for photocatalytic filtration/oxidation of collected biomass follows the UV bulbs. The photons from the UV bulbs are incident on both the PCO and PCF collectors. The PCO/PCF are self cleaning/self sterilizing modules. The final part of the system is a TSA regenerable canister with pleated panels, utilizing high efficiency microfibrous entrapment of small particulate catalysts and sorbents capable of 5-Log reduction of chemical threats.
