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.
