Abstract Okra gum, a polysaccharide consisting of D ‐galactose, L ‐rhamnose and L ‐galacturonic acid is used as food additive. In the present investigation, the flocculation efficiency of okra gum for the treatment of sewage waste water is tested. The flocculation study has been done by standard jar test method. The effect of polymer dose, contact time and pH on the per cent removal of solid waste is reported. Okra gum is found to be very effective and to be comparable with commercial flocculants. X‐ray analysis of the flocs is also reported to support the interaction of sewage waste with the gum.
