Abstract

LA INVENCION TRATA DE UN PROCEDIMIENTO PARA TRATAR LODO, EN ESPECIAL LODO DE CLARIFICACION, HASTA OBTENER GRANULADO. EN UN PROCEDIMIENTO DE ESTE TIPO SE LLEVA A CABO UNA CONCENTRACION PREVIA DEL LODO, UN TRATAMIENTO MECANICO SUBSIGUIENTE HASTA OBTENER GRANULADO Y UN SECADO DEL MISMO HASTA OBTENER UN PRODUCTO FINAL SUELTO Y APTO PARA SU USO COMO ABONO. GRACIAS A LA CONCENTRACION PREVIA HASTA UN ESTADO PASTOSO SOLAMENTE, CON UNA PARTE SECA QUE OSCILA ENTRE EL 40 Y EL 60 % Y EL SECADO DEL GRANULADO SUBSIGUIENTE AL AIRE CON RECUPERACION DEL CALOR SE CONSIGUE UN IMPORTANTE AHORRO EN CUANTO A GASTO DE ENERGIA Y DE APARATOS. ESTO SE HACE POSIBLE EN TANTO EN CUANTO EL MATERIAL PASTOSO, DURANTE LA PRODUCCION DE GRANULADO, EN CONTACTO CON EL AIRE LOGRA UNA COMPACTACION SUPERFICIAL QUE EVITA QUE SE PEGUEN LAS PARTES DE GRANULADO.
