Abstract

Изобретение относится к элементу керамического фильтра (22) для удаления жидкости из материала, содержащего твердые частицы, в капиллярном вакуумном осушителе. Элемент фильтра содержит керамическую подложку, покрытую микропористым слоем (31) спеченного керамического материала. Спеченный микропористый мембранный слой покрыт крупнозернистыми твердыми частицами (71) с размером частиц больше, чем размер пор в слое (31) мембранного материала, для формирования текстурированной поверхности (50), которая предотвращает соскальзывание отфильтрованного осадка с поверхности элемента фильтра до момента планового удаления осадка.
