Stirred Specific Volume Index (SSVI) determines the settling properties of an activated sludge. It is a simple test that is easy and quick to perform, and yet provides considerable information about the sludge settlement characteristics.
SSVI can be used both in routine plant operation and for designing a final sedimentation tank.
Type 311 PSU
The Type 311 Power Supply is built to run two SSVI units simultaneously.
Type 306 SSVIr
Monitor the settling rate automatically and record the SSVI history.
