摘要：

A pilot-scale evaluation of high rate filtration using both on-line turbidimeters and optical on-line particle counters was performed. At turbidities approaching the detection limit of the equipment (less than 0.05 ntu), particle counting proved to be a much better indicator of filtration performance. In addition, at these low turbidities, large changes in particle counts (one to two orders of magnitude) would register with only minor changes in turbidity (less than 0.02 ntu).
