Abstract

Las sales de cloruro de ciertos elementos de tierras raras tienen efectos beneficiosos como agentes clarificadores en el tratamiento primario de las aguas residuales. En la presente se describen métodos para tratar aguas residuales que comprenden la dosificación de aguas residuales, como parte de un sistema de tratamiento primario, con un agente clarificador de sales de cloruro de elementos de tierras raras, ya sea individualmente o en mezclas. Los agentes clarificadores de tierras raras se agregan o dosifican en cualquier punto corriente arriba de la operación de tratamiento primario, dentro de la operación de tratamiento primario, o tanto corriente arriba de, como dentro de la operación de tratamiento primario. También se describen en la presente agentes clarificadores para uso en el tratamiento primario de aguas residuales que comprenden una solución acuosa de sales de cloruro de los elementos de tierras raras.
