Abstract

PROCEDIMIETO PARA LAPURIFICACION DE AGUAS QUE CONTIENEN FENOL, EN PARTICULAR, AGUAS RESIDUALES DE LA FABRICACION DE RESINAS FENOLICAS, ENTENDIENDOSE BAJO EN CONCEPTO "FENOL" TODOS LOS DERIVADOS DE BEBCENO QUE SE VOLATILIZAN EN VAPOR DE AGUA SEGUN DIN 38409 H 16. EL PROCEDIMIENTO CONSISTE EN LA REACCION DEL FENOL CON FORMALDEHIDO, EN MEDIO ALCALINO, A 50-100 GRADOS C PARA FORMAR CONDENSADOS DE FENOL-FORMALDEHIDO QUE, POR ACIDIFICACION POSTERIOR DEL AGUA RESIDUAL, PRECIPITEN EN FORMA GRANULAR FILTRABLE Y NO PEGAJOSA Y PUEDEN ASI SEPARARSE.
