Resumo:
Produced water consists in one of the biggest environmental concerns related to oil production activities. Humic Substances (HS) are naturally formed during the humification organic residues by microorganisms and present several properties, amongst them, the ability to bind great part of the metal ions. The present work objectifies the avaluation the viability of the use of HS in the treatment of produced water, consideraing three different humic compounds (HMC-1, 2 e 3). In relation to the time for complete coagulation/floculation, a variation of the times as a function of the concentration of HS was observed, in all three cases. HMC-3 presented the shortest times, well defined interface and supernatant of clear aspect. The results of barium content, after HMC addition, clearly present the reduction of the initial values. The biggest reduction being obtained by 4 mL HMC-1. Tests algae detected an increase in the chlorophyll, as well as in the algae average areas, being this effect was even more accentuated in the presence of HMC-3. The results of the test show the possibility of HS use in treatments which involve a coagulation/floculation step nad confirm the HS capacity to bind metal species such as barium. The tests with algae strongly indicates the positive contribution of the presence of produced water to its growth, especially in the case of the produced water with HS. These results reaffirm the great potential of the use of HS in environmental treatments.
