Development and Performance Evaluation of a Filtration Equipment to Reuse PFC Waste Solution Generated on PFC Decontamination

PFC (Perfluorocarbon) decontamination process is one of best methods to remove hot particulate adhered on the inner surface of hot cell and surface of equipment in hot cell. It was necessary to develop a filtration equipment to reuse the PFC waste solution generated on PFC decontamination due to the high cost of PFC solution and for minimization of the volume of second waste solution. The filtration equipment was developed to remove hot particulate in PFC waste solution. It was made suitable size and weight in consideration of hot cell gate and crane. And it has wheels for easy movement. Flux of the filtration equipment decreased with particulate concentration increase. It consists of pre-filter (1.4 μm) and final-filter (0.2 μm) for protection of the flux decrease along filtration time. It treatment capacity of waste solution is 0.2 L/min.
