Abstract

UN PROCESO PARA LA REDUCCION DE PATOGENOS EN DESECHOS DONDE EL LODO DESHIDRATADO CON UN CONTENIDO DE SOLIDOS ENTRE EL 10 Y EL 60% SE MEZCLA DENTRO DE UN TRANSPORTADOR (10) CON OXIDO DE CALCIO O CARBONATO CALCICO. LA HIDRATACION A HIDROXIDO DE CALCIO OCURRE CON UNA LIBERACION DE CALOR CONCOMITANTE. EL PH DEL LODO SE ELEVA ENTONCES Y EL CALOR DE LA REACCION DE HIDRATACION SE RETIENE LO QUE DA COMO RESULTADO UNA NEUTRALIZACION EFECTIVA DE PATOGENOS. EL TRANSPORTADOR (10) TIENE UN TORNILLO INTERNO (20) IMPULSADO POR UN EJE (22) Y TAMBIEN ELEMENTOS DE CALENTAMIENTO (11) Y UN AISLANTE EXTERIOR (12).
