Abstract: Hollow porous fibers containing adhered contaminants are cleaned to remove the contaminants by backflushing a liquid to fill the pores, and adding a flow of gas so as to form a two-phase mixture of gas and bubbles of liquid that can scrub the fibers, loosening the contaminants and allowing them to be flushed from the hollow fibers. The method is particularly useful for cleaning hemodialyzers used for dialysis and hollow fiber modules used in water treatment and separations. The two phase flow method is specifically effective in cleaning piping systems having high length to diameter (l/d) ratios.

Abstract translation: 清洁含有附着污染物的中空多孔纤维，以通过反冲洗液体以填充孔隙来除去污染物，并加入气流，以形成可洗涤纤维的气体和气泡的两相混合物，松开 污染物并使其从中空纤维中冲洗出来。 该方法特别适用于清洗用于透析的血液透析器和用于水处理和分离的中空纤维模块。 两相流法在清洗具有高直径（l / d）比的管道系统方面特别有效。
