This page is a summary of research in fluid-particle separation using the CDS (Continuous Deflection Separation) device. This device is used to capture particles from a liquid stream, such as in storm water particle removal. CDS, Inc. sponsored a laboratory test of the particle removal effectiveness of this device. Results of some of that testing is shown here.

The links below describe research using the CDS unit.
