|摘要||The main problems of recovery cutting oil from spent waste are high viscosity of cutting oil and high content of nano-size particle. This study combined an innovative rotational circular-plate ultrafiltration membrane filter with a scraping device to recycle the cutting oil and remove particles fouling cake attached to the membrane surface, and was able to maintain cutting oil filtrate flux above 6.65 l/m2/hr. Also, the proposed process is the practical solution for materials separation between highly viscosity liquid and fine particles even nano-size. The results show the filtrate of ultrafiltration membrane could meet the reuse requirements of less than 0.03% solid content. Analysis of blended oil characteristics under different blending ratios was conducted, showing the optimum blending ratio of recycled oil to new cutting oil was 6:4. The final production cost can be reduced over 27.4%. The
process can achieve waste reuse ratio of greater than 77.2%.
