Özet:

The purpose of this work was to evaluate the turbidity removal efficiency of Carica papaya seeds extracts as a natural coagulant for synthetic and river water samples. To achieve this objective, several jar tests were executed by applying different bio-coagulant dosages, at three concentration levels of raw water turbidity, according to standardized procedures. ANOVA was used to verify if there were statistically significant differences between the dosages applied, with a confidence level of 95%. High turbidity removals were achieved when the initial raw water concentration was equal to or greater than 200 ITU. Efficiencies of up to 90.7% were recorded for synthetic water samples, and 74.6% for river water when dosages of 50 mg/L were applied. It was shown that Carica papaya seeds extract has a high potential to be used efficiently in turbid water clarification.
