customer introduction
At Öresund, north of Malmö, is the Barsebäcksverket - a disused nuclear power plant operated by Barsebäck Kraft AB (BKAB). BKAB is currently working on dismantling and demolishing the nuclear power plant, which had two reactors. The used nuclear fuels were removed a long time, but demolishing the nuclear power plant is a dirty job that requires maximum safety and control. To keep the air clean in the demolition process, air purifiers from Camfil were used.
Air cleaner CC 6000 is used in industrial operations and the filter is capable of rotating air up to 6000 cubic meters per hour. The filters in the air cleaner hold the same filter class as filters in operating theaters in hospitals. The filters have two steps in the cleaning process, a pre-filter that captures the large particles and a HEPA filter that captures the much smaller particles. This ensures that maximum dirt and harmful particles are removed from the indoor environment. The air cleaners installed by BKAB have been used in several different sub-projects at the plant, including asbestos removal in connection with the demolition of the reactor tank. The insulation on the outside of the tank contained asbestos, and to be able to establish negative pressure, air cleaners were added to the facility. Air cleaner CC 6000 was also used for the general environment in the turbine hall. Samples show a significant difference in the air environment.
RESULT
With the help of a particle meter, BKAB was able to establish that Camfil’s air cleaner removes 90% of the particles from the indoor air. In terms of measurement. the smallest particles that are most harmful to health were removed extensively. Out of 1,312,000 particles that were measured before the filter, only 162,000 particles were present after the air cleaners were installed. Thanks to the air cleaners, the risk of clogging of the sampling filters are now reduced and, in return, they have a significantly better working environment.
