Abstract

Studies with miniature columns of granular activated carbon (GAC) demonstrated the importance of pH in the removal of total organic carbon and trihalomethane precursors from coagulated Mississippi River water. Mediante estudios con columnas de carbón activado granular (GAC) en miniatura, se demostró la importáncia del pH en la eliminación de carbono orgànico total y de precursores de trihalometanos en agua coagulada del río Mississippi. El desempeño del GAC mejoró significativamente a medida que el pH se redujo de 8,7 a 5,0. Un sencillo análisis de costos ilustro el concepto de un pH de operación óptimo.
