The SSVI can be used both in routine plant operation and it can be used for the design of a final sedimentation tank.

A complete operating manual is supplied with the SSVI equipment that details how the SSVI test is performed and how the results are interpreted.

The equipment consists of the following items:

• Slow speed stirrer and timer unit
• A Perspex tube with a 50 cm graduated scale and stirring paddle
• Power supply (separate unit Type 311)
• Portable Power pack (Type 324)

The timer unit defaults to the standard 30 minutes test time, but it can be set for any time between 1 and 99 minutes.

At the end of the test the timer emits an audible signal.

The Type 324 power pack is a small rechargeable battery pack the has enough charge to perform 32 single tests. There is a clear 5 LED indictor to show the charge level. Each unit is available with mains or car charger options.
