Abstract
Introduction. In this research project, natural
coagulants Opuntia ficus-indica and Moringa oleifera
were used, and their performance against aluminum
sulfate (Alum) was compared. Objective. Evaluate
the performance of three coagulants for the
removal of suspended and dissolved solids to treat
the water of the Magdalena River. Materials and
Methods. Initially, unit operations such as peeling,
drying, crushing and sieving (6 mm mesh) were
used to convert Moringa oleifera and Opuntia ficus
into powders. The main variables to be analyzed
were turbidity and the correlation of turbidity and
absorbance, which were found with the help of a
turbidimeter and a spectrophotometer, respectively.
The dose of clarifiers to be used for the samples
was determined using an experimental design of
8x3x2. Results. The results were compared with
the coagulants, both separately and mixed, to verify if
the use of aluminum sulfate in the given percentages
alters the clarification. We compared the acceptable
values of the physicochemical parameters for drinking
water of 2 UNT for turbidity and between 0.10 and
0.20 for absorbance, indicated in the Colombian
regulations. Conclusion. The obtained results
allowed to conclude that mixing Moringa oleifera and
Opuntia ficus can remove a percentage of turbidity
greater than 90.0 %, in comparison with the mixture
of alum and natural coagulants, which can remove at
least 99.0 % of turbidity in the water. In turn, it was
possible to evidence a decrease in the solids by means
of absorbance.
