Turbidity Sensors

In bioprocess operations, the turbidity of the liquid after a filter can be measured as an indication of filter performance. It can also be used to measure unclarified material directly from a bioreactor or fermentor.

The measurement may indicate undesired components are “breaking through” the filter meaning the filter is losing its capacity. The turbidity measurement at 880nm can be used in conjunction with pressure measurements in constant flow filtration processes to give an overall measurement of filter performance. To make an online turbidity measurement, use a device such as the Turbidity Flow Cell versus taking a discrete sample and measuring offline.
