M.Tech.Chemical Engineering. / The distillery wastewaters released from industries that use molasses as a major source of carbon in their fermentation processes pose serious threats to the water quality in several regions around the globe. Melanoidin is an antioxidant that results from the Malliard reaction found in fermentation and distillation processes. This study explores the removal of melanoidin from aqueous solution using natural clinoptilolite modified using cationic surfactant hexadecyltrimethyl ammonium bromide. The absorbent media was characterized using analyatical techniques such as BET, FTIR, SEM-EDS and XRD analysis. Given the relatively low cost of natural zeolite, it is possible to apply the sorbent in polishing distillery wastewater after a biological process. Since both natural zeolites and distillery waste streams are used in agriculture, a prudent way to dispose the spent media is to use it as fertilizer in farming.
