12.0 Definitions
Anionic:
Negative charged ions.
Automatic Control:
Placing the control of the dosing pumps under the control of the
Streaming current monitor. The Optional PI controller is
recommended.
Brownian Motion:
A phenomenon which occurs when microscopic particles are
suspended in a solution due to their random bombardment by the
fast movement of water molecules.
Cationic:
Positive
charged
ions.
ICu:
Ion Charge unit. 1 ICu is approximately equal to 1 mA of charge.
1 ICu = 1 SCU.
Ion Charge
Analyzer:
Another name for a Streaming Current Monitor.
PI Control:
Proportional Integral Control .A process control algorithm that
allows for a faster, tighter control.
PID Control:
Proportional Integral Differential Control. A higher level control
algorithm than PI control, but not required in Streaming Current
applications.
Silt:
A collective of finely divided clay particles and organic matter
suspended in water.
Zeta Potential:
The charge potential required to induce particle mobility when
placed under the influence of an electric current.
SCU:
Steaming
current
unit. 1 SCU = 1ICu.
