A Mathematical Approach to Replenishment Techniques

Samuel R. Goldwasser

Equations are derived for use in calculating formulas and rates of addition of replenisher solutions. Replenishment formulas and rates are determined not only by chemical reactions between constituents of the film and the solutions, but also by physical characteristics of the equipment in which the film is processed. When values for carry-over, tank volume, overflow, film velocity-chemical activity, and concentration levels are inserted in appropriate equations, replenisher formulas and rates can be calculated. The application of the equations to a typical problem is shown.
