Recently, the disposal of waste oil-in-water cutting emulsion has become an urgent issue because its extremely high chemical oxygen demand (COD). The present work focuses on treating generated from Samsung Thai-Nguyen factory in Vietnam. This used multistage methods to treat meet wastewater requirement and characterize oil recovered. consist flocculation method (stage 1) Fenton oxidation 2). after stage 1 treatment a COD reduction efficiency 98.24% at condition pH 5, Al2(SO4)3 2 g/L, C-PAM...
Waste cutting fluids are considered as hazardous wastes because they contain numerous different components causing environmental problems. Normally, a flocculation method is applied to treat preliminarily. However, the output wastewater still needs treating further meet national standards of industrial before disposal. So, this research reports secondary treatment stage waste fluid collected from an factory in Vietnam using zero valent iron (ZVI) catalyst. This catalyst was synthesized via...
