DISCUSSION ON TREATMENT EFFICIENCY OF REACTIVE YELLOW 145 COLOR AND REACTIVE RED COLOR 194 BY GUM EXTRACTED FROM MORINGA OLEIFERA SEEDS

Abstract

The treatment of wastewater , in general , and wastewater containing dyes , in particular, has long been studied, to find not only effective treatment methods but also treatment materials that do not generate additional pollutants. These should be eco- friendly and inexpensive material s which also , make use of discarded or rarely used resources. The current trend is towards a circular economy where waste from one industry is an input for another and helps to reduce environmental pollution. In this study, a biological coagulant (gum) extracted from moringa seeds is produced as a coagulant to treat Reactive Y e llow 145 (RY145) and Reactive Red 194 (RR194). The material's properties are determined by scanning electron microscopy (SEM) and FTIR analysis methods. SEM images show that the surface structure of the gum biomaterial extracted from moringa seeds has the appearance of relatively fine pores and relatively homogenously distributed gum particles on the surface. FTIR spectra indicate that the prepared material contains surface functional groups such as –OH, –HC=O , and C-O of the xyloglucan ring. The factors affecting the coagulation process of RY145 and R R 194 colors include pH, gum concentration, initial color, stirring speed , and stirring time. From the empirical results, it is suggested that the bio-flocculating agent (gum) prepared from moringa seeds, an eco-friendly material , can decolorize and reduce COD, and thus, possess great potential for application in the treatment of textile dyeing wastewater, with RY145 and COD removal efficiency of 87.77% and 76.92% respectively, and RR194 and COD removal efficiency of 89.31% and 80% respectively.
