Abstract

Un método para tratar y recuperar compuestos de fosfato de agua residual que contiene fosfato. El método incluye pasos de (a) extraer el fluoruro del agua residual; (b) recuperar el compuesto de fosfato del agua residual al mantener las condiciones de sobresaturación para el compuesto de fosfato; y (c) pulir el agua residual. Un paso de extracción de sílice se pueden realizar opcionalmente después del paso (a) y ante paso (b).
