Decoloration of an Effluent from Textile Industry using Moringaoleifera Seed Extract

Abstract

This research evaluated the removal of textile dyes by the physicochemical process of coagulation-flocculation using a natural coagulant extracted from the seed of the Moringaoleifera tree. The seed was collected and two different coagulants extracts were prepared: simple extract and saline extract. For the experimental essays, synthetic samples were prepared in the laboratory using three azo dyes with different chemical structures; direct blue 71, reactive red 2 and acid yellow 23, its decoloration was evaluated individually and in mixtures. Also, a wastewater sampling was carried out in a textile plant located in the municipality of Zinapecuaro, Michoacan and tests of coagulant activity and determination of optimal parameters for the process were carried out, this was accomplished through the simulation of jar test and measurement of absorbance using an ultraviolet-visible light spectrophotometer to determine the percentage of visible color removal.
