摘要
In this work, the use of membrane separation processes (MSP) for the treatment of a synthetic effluent from a nanoceramic coating line was evaluated. Three MSP were tested: electrodialysis, microfiltration, and nanofiltration (NF). The presence of zirconium, a chemical element able to combine with different compounds producing complexes, and pH variations in the nanoceramic effluent are responsible for the different efficiency levels of the MSP in treating this effluent. The better results were reached with NF, making this process an option for the treatment of this new effluent.
