The present study was investigated to find the efficiency of a hybrid process of an ecofriendly dehydrated Moringa oleifera biosorbent beads and ultrafiltration (UF) membrane to remove organic pollutants from the actual textile effluents. Experiments were conducted under packed bed column (PBC) for the removal of dyes using various parameters such as flow rate, material mass and size of the biosorbent. The optimized biosorption process was then combined with dead-end UF process for the removal of COD/BOD and turbidity. Three strategies were adopted by varying the sequences of UF and PBC. The PBC followed by UF process appears to be more effective for the removal of color (>99%), COD (90–93%) and turbidity (>95%), when compared to UF followed by PBC process and UF membrane alone. The results suggested that the treated effluent could be reused in industries for various purposes such as floor cleaning, gardening, etc.
