The Boltac Coagulation & Flocculation Simulator is
a device used to simulate the process by which water is
cleaned. The addition of both primary and secondary
coagulants and coagulant aids can be simulated in this
machine (otherwise known as a Jar Stirrer or Jar Tester,
or alternatively as a Floc Tester). Knowing how to relate
the results of a jar test back to the plant operation is
the key to success.
The process being simulated is normally taking place
in a vast settling tank, in which up to five million
litres can be in process at one time. Once proficient, an
operator can gain accurate results using 4 or 6 litres
per test. Depending on the design of the process being
simulated, the jar test can show results in as little as
30 minutes, compared to up to a number of hours when
monitoring the actual process.
If a change is to be made without first ascertaining
the amount or direction of the change, costly, (sometimes
dangerous), and embarrassing errors can be made. The
practised and frequent use of the machine can lead to
chemical savings, adherence to performance criteria, and
a definite aid to Quality Assurance auditing.
