Impressed current system efficiency

Avoid using too few high output anodes relatively poor distribution efficiency increases the requirement of current (applies to sacrificial anode and impressed current systems). 

The electric current I that is impressed at the electrodes is not necessarily the same current that passes through the cells or deionizing compartments. The acmal current that successfully passes through is a function of the current efficiency which varies with the nature of the electrolyte, its concentration in solution, and the membrane system. Call Mthe current efficiency. The amperes passing through the solution is equal to the amperes required to remove the ions. Thus,...
