Fundamental and pilot-scale experiments were conducted to develop a laundry waste treatment system for a nuclear research center. The system is composed of a preconcentration step with reverse osmosis (RO) unit, a volume reduction step with ultrafiltration (UF) unit, and the final purification step with RO unit. At the RO process, the waste was concentrated over the critical micelle concentration on the basis of surfactant concentration. The performance of the UF process was investigated by adsorption experiments of radionuclides on the micellar surface and the separation of the micelles. Under the experimental conditions studied, the overall volume reduction factor over the entire processes was 250 and the average decontamination factors of C{sup 60} and Cs{sup 137} were 110 and 20 respectively.
