The organic matter removal by microorganisms in the filters could be attributed to microbial metabolism, secondary utilization and microbial adsorption. Some factors such as filter media, EBCT, water temperature, backwash and filter closedown had some effect on organic matter removal.

微生物对有机物的去除由生物代谢、二级利用和生物吸附等多种作用共同完成，其去除效果受滤料介质、空床接触时间、水温、反冲洗方式以及滤池关闭等多种因素的影响；

In 6 cases with 11 coronary bypass grafts, EBCT studies showed graft patent in 6 and occluded in 5, which was confirmed by conventional graft angiography.
