Descripción

The objective of this study was to evaluate the reduction of turbidity in water samples from the Bogotá river, using the guava seed, Psidium guajva L, and the avocado seed episperm Persea americana, as natural coagulants. Three extracts were made from each seed, in water, with 10% ethanol and 10% acetic acid. Three tannins were used as an organic control: quebracho (Schinopsis balansae), mimosa (Acacia dealbata) and chestnut (Castanea sativa), with aluminum sulfate, Al2(S04)3 as the inorganic control. The samples of water were taken from the upper basin of the Bogotá river in the Chocontá - Villapinzón route to La Marinilla. A reduction in turbidity levels was observed in all cases, using the 10% acetic acid extract of Psidium guajava L, with an effectiveness of 94.95%, and of 93.71% using the extract of this same seed in water. Likewise, the episperm of the Persea americana avocado seed showed reduced levels of turbidity. The extract in 10% acetic acid was the most effective, with a percentage of 80.85%. The chestnut one showed the best yield of the three tannins with a maximum effectiveness of 91.75%
