This paper focuses on the applicability of microfiltration (MF)/ultrafiltration (UF) as a pretreatment to nanofiltration (NF) for the reclamation of rinsing waters of indigo dyeing process. Two different MF alternatives, single 5 mm MF and sequential 5 mm'/0.45 mm MF, were evaluated as prefiltration

The results have indicated that MF could be an alternative for the pretreatment of indigo dyeing wastewaters. Membranes with pore sizes smaller than 1.2 µm provided relatively low COD but high color rejections. The COD rejections somewhat improved when wastewater pH adjusted to a neutral value.
