Abstract
TRATAMIENTO DE AGUAS RESIDUALES. LAS AGUAS NEGRAS CONTENIDAS EN TANQUE (10) SIN DEPURAR O AGUAS RESIDUALES SIMILARES SE MEZCLAN CON LODO ACTIVADO (14) Y LA MEZCLA RESULTANTE SE HACE CIRCULAR EN UN TANQUE AIREADO CONFINADO (20), DE FORMA QUE LA MEZCLA SIGA UN CICLO DE FLUJO VERTICAL PREDETERMINADO A TRAVES DE UNA PLURALIDAD DE CONDUCTOS DE PASO DE FLUJO, CREADOS POR UN ELEMENTO DEFLECTOR (30) IMPERMEABLE AL GAS, CON EL FIN DE AUMENTAR EN GRADO OPTIMO EL TIEMPO DE RETENCION DEL AIRE DE AIREACION EN EL TANQUE. EL DEFLECTOR SECUNDARIO SE SITUA ADYACENTEMENTE POR ENCIMA Y SUSTANCIALMENTE PARALELO AL ELEMENTO DEFLECTOR IMPERMEABLE AL GAS QUE SIRVE PARA DIRIGIR EL FLUJO.
