Abstract

Способ и устройство для проверки эффективности очистки для фильтра в системе фильтрования. После процедуры (21) очистки фильтра, поры фильтра содержат жидкость (22). Систему герметизируют (23) и измеряют (24) понижение давления на протяжении предварительно определенного периода времени. На основании понижения давления определяют, действительно ли очистка была эффективной (25); понижение давления, меньшее чем предварительно определенное пороговое значение, указывает, что процедура очистки была неэффективной.Международная заявка была опубликована вместе с отчетом о международном поиске.
