The use of Moringa oleifera Lam. seeds appears as a low cost and sustainable
alternative for the treatment of water, considering that there are already researches
that prove its potential. The objective of this work was to verify the effect of different
concentrations of the Moringa oleifera Lam. seed powder applied in water samples
from the Xingu River. The experimental trial had 6 treatments with different
concentrations of the powder added to the water samples, besides the control: T0
(water, without addition of powder); T1 (water with 80 mg.L-1 of powder); T2 (water
with 120 mg.L-1 of powder); T3 (water with 250 mg.L-1 of the powder); T4 (water with
500 mg.L-1 of the powder); T5 (water with 1000 mg.L-1 of powder) and T6 (water
with 2000 mg.L-1 of powder). The solutions, with the appropriate concentrations,
were maintained in an environment with controlled temperature of 25 ° C for 24
hours. The analyzed parameters were: Free Chlorine; Apparent Color; Total Iron; pH;
Turbidity; Total Escherichia coli and Coliform. The use of Moringa oleifera Lam. seed
powder was efficient in relation to the parameters Residual Chlorine Free, Total Iron
and Turbidity, showing great potential in its use for water treatment. The use of the
Moringa oleifera Lam. seed powder significantly altered the parameters described
above, as well as not interfering with the pH value. However, in order to obtain a
water suitable for human consumption, it is necessary to combine the treatment with
other techniques, in order to obtain the appropriate values required by community.
Therefore, it is recommended to carry out more research using the seeds of Moringa
oleifera Lam. in the treatment of water, due to the numerous advantages of using this
method in both social and environmental issues.
