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

In this study, the degree of goodness fit presented by San model is determined to calculate percentage removal flocculent particles, when initial turbidity in problem water low. For this, frequency analysis historical data that enters four drinking treatment plants located department Cundinamarca (Colombia) made, which show values range between 0.60 and 15.08 NTU (Nephelometric Turbidity Units). The coagulation was done using type A aluminum sulfate sedimentation test carried out a tower order determine remaining water, allows calculating for different times at depths. constants were through multiple linear regression performed coefficient determination R2 water.
