A Simple Plant Method of Estimating the Alkaline Constituents of Washing Powders and Washing Solutions Containing Mixed Alkalies

Meadow Gold Milk Plant, Oklahoma City, Oklahoma

ABSTRACT

With the new developments in cleaning in the dairy industry and the great number of new cleaning powders on the market, each making astounding claims for their product, the dairy plant manager is greatly in need of a simple, rapid plant test by which he can determine the approximate ingredients of the various cleaners in order to evaluate their worth. Many plant operators use a mixture of two or more alkalies in the soaker compartment of their bottle washing machine. Some alkalies possess the ability of maintaining their strength in solution longer than others. Therefore in order to maintain a constant balance between the different alkalies it becomes necessary for the plant operator to be able to determine the amount of each alkali present at frequent intervals.

The most satisfactory method of determining the ingredients in a solution of mixed alkalies consists in titrating a sample of the alkali with standard acid to the phenolphthalein end point, taking the reading and continuing the titration to the methyl orange end point.
