05 March 2018

Working with the EM Office of River Protection (ORP) and Bechtel National Inc. (BNI), the Porvair team developed a first-of-a-kind high-efficiency particulate air (HEPA) filter for use in the Hanford plant in Richland, Washington.

Porvair Filtration Group have developed a filter which is not only five times stronger than a standard HEPA filter, but it also meets or exceeds the requirements of both ASME AG-1 code and the Vitrification Plant environmental conditions. The filter helps give greater protection to the environment and the public during operations.

The WTP, which is currently under construction by Bechtel in the US, will use the filter across the plant’s three nuclear processing facilities; Pre-treatment, Low-Activity Waste (LAW), and High-Level Waste.

The ability to filter harmful particles and contaminants from ventilation and off-gas systems make HEPA filters critical to the nuclear industry.
