The study focused on the physico-chemical characterization of raw water samples from the Kongou Gorou pond treated with almond powder from Moringa oleifera seeds. The powder which was used for the present study was dried in the oven for one month at the respective temperatures of 25, 40 and 50 ° C and then applied at a dose of 100 mg /L. The parameters studied are pH, iron, copper, electrical conductivity, rate of dissolved substances (TDS), hardness, organic matter; calcium, HCO3-, magnesium, the Complete Alkalimetric Title (TAC).

The physico-chemical analysis showed that the waters studied have concentrations below the standards recommended by WHO in 2009. For the dose of 100 mg/L and stored at the respective temperatures of 50, 40 and 25 ° C, it was recorded: a pH close to neutrality, a reduction in iron content of 93.46% at 50 ° C, 90.76% and 90.76%, a decrease in magnesium of 27.21; 27.89 and 39.96%, a decrease in hardness of 37.98; 39.94 and 36.03%; a decrease in the TAC from 1.3 to 1.18; 1.29 and 1.23 ° F and finally a reduction of 9.26; 0.81 and 5.42% bicarbonate. At these respective temperatures of 50, 40 and 25 ° C, the electrical conductivity has increased by 33.63, 33.05 and 32.8µs.cm / L at 2 hours of settling and from 34, 64, 34, 28 and 36, 23 µs. cm / L at 24 hours of settling; an increase in the rate of Dissolved Substances from 15.21 to 16.32; 16.33 and 16.72 mg / L; an increase in the order of 34.48, 26.72 and 13.79% in calcium levels; an increase on the one hand of copper from 0.114 mg/L to 0.903 and 2.39 mg/L respectively at 50 and 40 ° C and on the other hand a total removal of the latter at 25 ° C.

The results showed that the use of Moringa oleifera seeds effectively improves the physicochemical quality of the treated water, which not only meets the WHO drinkability standards but also the characteristics of water suitable for drip irrigation.
