Pulsed Jet Self Cleaning System

Pulsed jet cleaning is a process developed by Porvair Filtration Group for the effective removal of collected solids from the surface of a filter element.

Our Pulsed Jet self-cleaning gas filtration systems are used across the industry in the UK, USA and Europe, in both uranium oxide and plutonium/uranium oxide (MOX) fuel processes, including:

•  Pre and post enrichment, including fluorination and defluorination
•  Uranium oxide powder recovery
•  Plutonium oxide powder recovery
•  Pellet finishing grinding dust removal and recovery
•  Process glove box venting
•  High temperature fuel process, including hydrogen fluoride (HF) service
•  Sintering furnace off-gas
•  Plutonium and uranium powder storage vents
•  Spent fuel dry store processing and vent filters
•  Uranyl nitrate to trioxide conversion systems
•  Reprocessing filter systems.

The back-pulse process is typically undertaken whilst the filter is in operation on-line and, apart from a very small pressure spike (or ‘overpressure’), it does not interrupt or interfere with the process flow.
