PULGARIN-MONTOYA, Diego Alejandro; DE PLAZA-S., Juan Sebastián; RUGE-C., Juan Carlos y ROCHA DE ALBUQUERQUE, Paulo José. Analysis of the goodness of fit of the San model for the calculation of the removal percentage of flocculent particles with low initial turbidity values in the problem water. Dyna rev.fac.nac.minas [online]. 2021, vol.88, n.219, pp.28-34. Epub 14-Mar-2022. ISSN 0012-7353. https://doi.org/10.15446/dyna.v88n219.91441.
In this study, the degree of goodness of fit presented by the San model is determined to calculate the percentage of removal of flocculent particles, when the initial turbidity in the problem water is low. For this, the frequency analysis of the historical turbidity data that enters four drinking water treatment plants located in the department of Cundinamarca (Colombia) is made, which show values that range between 0.60 and 15.08 NTU (Nephelometric Turbidity Units). The water coagulation was done using type A aluminum sulfate and the sedimentation test was carried out in a sedimentation tower in order to determine the remaining turbidity in the water, which allows calculating the percentage of removal for different sedimentation times and at different depths. The values of the constants of the San model were determined through a multiple linear regression and the goodness of fit test was performed by calculating the coefficient of determination R2 for the different initial turbidity values in the test water.
