Abstract

Una criba estática posee una pluralidad de cuerpos de criba y una pluralidad de dispositivos de aireación corriente debajo de los cuerpos de criba. Cada dispositivo de aireación se asocia con un grupo de uno o más cuerpos de criba. Cada dispositivo de aireación podrá ser un aireador pulsante. Los aireadores pulsantes no liberan aire al mismo tiempo. Cada cuerpo de criba funciona en períodos de filtración en línea separados por eventos de retrolavado. Los eventos de retrolavado comprenden introducir un golpe o pulso de aire en el fondo del cuerpo de criba. El flujo por la criba estática continúa en todo momento porque los cuerpos de criba no son sometidos a retrolavados al mismo tiempo. La criba estática podrá usarse para eliminar suciedad del agua que fluye a una unidad de membrana sumergida. Alternativamente, la criba estática podrá usarse para proveer tratamiento de agua de desecho primaria.
