Abstract

PROCEDIMIENTO PARA LA ELABORACION DE LODOS DE AGUAS RESIDUALES. EL PROCESO SEGUIDO POR LOS LODOS ES EL SIGUIENTE: DECANTADOR CENTRIFUGO (2), DONDE SE ELIMINA EL AGUA, BOMBA (4), GRANULADOR MEZCLADOR (5), ALIMENTADO POR EL SILO DE GRANULADO SECO (6), SECADERO DE LECHO DESLIZANTE DE CONTACTO (12). EL SECADERO SE ALIMENTA DE CALOR A TRAVES DE LOS CAMBIADORES (16). LOS GASES GENERADOS DURANTE EL SECADO SON IMPULSADOS POR LAS SOPLANTES (19, 20) DESDE EL SECADERO (12) A LAS CAJAS DE DISTRIBUCION (18), E IMPULSADOS NUEVAMENTE A TRAVES DEL LECHO CON OBJETO DE FLUIDIZARLE ALGO MAS. LA CALDERA (27) QUEMA GRANULADO SECO PROVENIENTE DEL SECADERO Y ALMACENADO EN UN SILO (30). H
