Efecto del riego con agua residual tratada en el ph y la acumulación de sales

Abstract

The treatment of wastewater by facultative lagoons generates as a product a water that meets sanitary standards, but which has a significant organic and nutrient load, a product of the activity of the photosynthetic algae used in the process. The use of these treated wastewater (ART) for irrigation is an opportunity to take advantage of these resources to obtain a by-product and generate value, especially in arid areas, while avoiding dumping into water receiving bodies and the potential risks of eutrophication. . However, it is also an environmental risk since negative effects have been reported, such as increased salinity and sodicity and nutrient overload, which can affect crops, accumulate in the soil or leach out, and affect water sources.
