RESUMO:

The water produced is extracted together with the oil and represents the largest waste stream in the production of crude oil. The aspects that deserve attention are its high volumes and the complexity of its composition. Disposal of such waste volumes has raised concerns about uncontrolled environmental pollution and is irreversible in the marine environment.

So the removal of these contaminants is considered a major problem, a challenge in the world today, but can be seen as an opportunity to provide a viable source of water, as beneficial in many applications, for which the quality of drinking water is not avoiding serious environmental damage. Thus the development of technologies through the adsorption of cations and anions is efficient and simple and has been used in for the remediation of waters and effluents.

In this work, treatments were carried out in water produced through the adsorbent commercial zeolite A, through a planning in which its adsorption capacity was compared as a function of the contact time with the produced water, in periods of 0 (without treatment) to 24 hours , at the end of the treatment, the samples were analyzed by ICP-OES. Also, different materials such as zeolites, aluminas and Lamellar Double Hydroxides were used. It was observed that for zeolite materials A, ɣAl2O3 and calcined commercial HDL were the most satisfactory results with a percentage of 60% to 99% of removal and when compared to the maximum permissible values established by Resolution No. 430 of the National Council of the Environment Environment, and finally the synthesis of a new composite material based on Zeolite A and HDL, being a material with specific properties for the simultaneous removal of cations and anions, being efficient for remanage in petroleum produced water.
