USO DE AGUAS RESIDUALES PARA EL RIEGO DEL CULTIVO DE FRIJOL

Abstract

In Guatemala, agriculture is the activity that consumes about 70% of water. The reuse of wastewater by irrigation can be a low-cost alternative to properly dispose of water, avoiding that this wastewater reaches other bodies of water and it causes pollution problems and also being given a proper use to this resource that is increasingly scarce. We analyzed various domestic wastewater effluents from the treatment plant Aurora II, Guatemala. These waters were used to irrigate the crop of bean (Phaseolus vulgaris L.). The best results in terms of the height of the bean crop plants were obtained which were irrigated with wastewater from the primary settler and the effluent from first trickling filter with rock material as a filter medium.
