RESUMO

This work considers new technology for effluent treatment generated by the dairy industries. Currently this type of effluent, when treated, uses the biological process to reduce the organic load, however, this method, some times, does not guarantee the complete removal of organic composites. Thus, the sodium bentonite use is suggested for the adsorption of the lactose as tertiary treatment of the effluent one of the dairy industry. The evidence of this event as well as its quantification was carried through two distinct techniques: thermal analysis and x-ray diffraction. The gotten results had been positive, therefore the adsorption not only proved the absorption of the organic material, in the case, the lactose in the evaluated clay. It was verified capacity of the Wyoming bentonite of to ab-adsorption up to 50% of the lactose. Therefore, this work offers alternative for the tertiary effluent treatment of the dairies industries.
