In the KDF filter, effect of contact reaction time, filter bed height, and filteringvelocity on lead and mercury removal was studied.
以KDF为滤料,研究了接触反应时间、滤层高度和滤速对铅和汞去除效果的影响。

It was believed that the primary reason of the second propagation of Cyclops was the low filteringvelocity and the long retention time in the filters.
指出滤池滞水区停留时间长、流速低是造成剑水蚤二次繁殖的主要原因。

The result shows that selection of suitable contact reaction time, filter bed height, and filteringvelocity may result in efficient removal of lead and mercury.
