Abstract

Un procedimiento para tratar un efluente que contiene un tinte dispersable en agua o soluble en agua, caractereizado porque el efluente, por ejemplo de un procedimiento de tinción textil, se mezcla con óxido de magnesio y después se separan los sólidos del efluente, por ejemplo por decantación, filtración o centrifugación; se ajusta el pH del efluente preferiblemente a un valor de 6 a 8 antes de mezclarlo con el óxido de magnesio.
