Waste Packaging and Storage

Porvair Filtration Group actively supports the nuclear waste treatment and storage industry. As processes are developed to deal with legacy wastes and legislation is introduced to define storage conditions, we are at the forefront of developing novel solutions to meet increasingly complex filtration problems through our extensive research programme. 

Vent breathers

Using a range of metallic filter media in a variety of metal types, Porvair is able to supply waste package breathers that are precisely tailored to the individual needs of any application.

Available with defined separation efficiencies, gas diffusion and flow/∆P characteristics.

In addition, we are working with the nuclear industry to improve the efficiency, safety and cleanliness of cementation, vitrification and disposal technologies including: 

• Drum filling, cement dust collection pulsed jet system
• Vitrification plant, high temperature, pour and drain vent filters
• Bulk vitrification pre-treatment evaporator filter systems.
