CALIDAD AGRONÓMICA DE EFLUENTES DE PLANTAS DE TRATAMIENTO DE AGUAS RESIDUALES

Abstract

En la ciudad de San Luis Potosí, México, se encuentran en operación seis plantas de tratamiento de aguas residuales, los efluentes son usados en el riego agrícola, lo cual es conveniente tomando en cuenta el clima árido de esta ciudad. Para un mejor aprovechamiento de este recurso se realizó el presente estudio donde se evaluó su calidad agronómica a través de doce indicadores, los cuales no aparecen en la norma oficial mexicana NOM-003-ECOL-1997, la cual especifica la calidad de dichas aguas para su reutilización. Los resultados revelan que los efluentes son de buena calidad en cuanto a RAS (< 10 me L-1) y pH (6.5-8.4). El resto de los indicadores fueron: conductividad eléctrica, salinidad efectiva, salinidad potencial, carbonato de sodio residual, RAS ajustado, reducción de infiltración, cloro, boro, sodio y sólidos disueltos totales, todos ellos resultaron condicionados de manera general. El mejoramiento de estos indicadores, y por lo tanto, la reutilización sustentable de este recurso, es posible a través de diversas opciones tecnológicas que se exponen y que son accesibles a los productores. Una de las medidas relevantes es la adecuación de los instrumentos jurídicos relacionadas a la reutilización agrícola de los efluentes, para tal situación se deberá de crear una mayor evidencia a nivel nacional que refuerce esta propuesta.
