88-11: An Alternative Cooling Water Treatment Program for the Replacement of Cleaning Systems

88-11: An Alternative Cooling Water Treatment Program for the Replacement of Cleaning SystemsAn alternative cooling water program has been developed to replace chromate. Ultra low levels of zinc (0. 5 2. 5 ppm) have been determined to provide near comparable results in many applications to the chromate type programs. The new program has a wide application range for calcium (15 to 1000 ppm as CaCO3) and pH (7. 3 9. 0).

The driving force was often “image”

This really isn't too surprising since cooling water systems contain many opportunities for corrosion to occur

To determine the potential for movement of drift derived chromium to surface streams

In many cases

all were affected by at least one of the contaminants

The turbidity of river water varies in the range of 70-500 NTU with lower value typically noted in the summer and higher value during the rainy season

During the past decade

A model for the calculation of drift deposition from salt water cooling towers has been developed

The main computer program options are then discussed
