Experiencia de aplicación de microorganismos efectivos nativos (MEN) para el tratamiento de aguas residuales

Fecal contamination is one of the main freshwater quality problems worldwide. One proposed solutions for this problem treatment effluents at domestic orlocal level with microbial consortia such as effective microorganisms from native origin (MEN in Spanish). In work we evaluated ability a MEN formulation produced Uruguay to reduce fecal effluents. To achieve this, experimentswere carried out different scales, vitro septic tanks and section Malvín stream (in situ), combining liquid solid using coliforms (FC) particulate organic matter performance indicators. Both laboratory tanks, CF decreased significantly after 8 weeks ofapplication. stream, decrease visual recovery water course were observed, increased transparency dissolved oxygen concentration. The results suggest that application wastewater represents promising approach andemphasize need change manufacturing habits management tanks.
