Abstract

LA DESNITRIFICACION BIOLOGICA DEL AGUA SE MEJORA DECIDIDAMENTE, REDUCIENDO POR UNA PARTE EL CONTENIDO EN OXIGENO EN EL AGUA ANTES DE HACERLA PASAR A TRAVES DE LA ETAPA DE DESNITRIFICACION, Y REALIZANDO POR OTRA PARTE EL CONTACTO DEL AGUA CON LAS BACTERIAS DE DESNITRIFICACION EN UN LECHO DE TORBELLINO FORMADO POR ARENA, SOBRE CUYOS GRANOS SE HAN CULTIVADO DE FORMA CONTROLADA BACTERIAS DE DESNITRIFICACION DE LA ESPECIE <PSEUDOMONAS FLUORESCENS>. EN CONSECUENCIA EL DISPOSITIVO PARA LLEVAR A CABO ESTE PROCEDIMIENTO PRESENTA UNA ETAPA (51) ANTEPUESTA AL REACTOR DE DESNITRIFICACION (52), PARA LA ELIMINACION DE OXIGENO. CUANDO ESTA ETAPA ESTA REALIZADA COMO ETAPA DE DESGASIFICACION AL VACIO, ENTONCES A CONTINUACION DEL REACTOR (52) ESTARA DISPUESTA CONVENIENTEMENTE UNA ETAPA DE DESCARBONIZACION (81).
