Solution After a discussion of various options for increasing cycles to reduce water and chemical usage while addressing the scale problem, the decision was made to convert to a ProChemTech SofTek tm program using cation softened water as cooling tower makeup. ProChemTech supplied water softeners for the three separate cooling tower systems with installation being completed in October, 2006. The ProChemTech SofTek water management program was implemented following equipment installation and startup.

System Information The cooling tower systems consisted of three, separate galvanized steel, plastic fill cross flow units of 500 tons capacity each typically operating 24 hours per day, seven days a week with high efficiency copper tube chiller condensers running from 50 to 105% of load. The water management program uses conductivity controlled blowdown with timed biocide addition and makeup proportional chemical feed. Three place corrosion coupon racks were installed in 1997 when the systems were being operated at 3 to 4 COC. Treatment with hard water makeup consisted of a molybdate traced PBCT phosphonate and terpolymer product with azole, hydrogen peroxide was used as the biocide during this time period, 1995 to 2006.

The new ProChemTech SofTek water management program uses a single inhibitor product with a single oxidizing biocide, PCT 3026 - n, n, dibromosulfamate, with COC maintained between five (5) and six (6). Molybdate was replaced with BlueTrace tm as the control tracer in the new inhibitor to reduce product cost and as a way to simplify control testing.
