Minimize Blowdown

Blowdown should be carefully monitored and controlled. The concentration of dissolved solids is controlled by blowdown. If the concentration of dissolved solids gets too high, it can lead to corrosion problems.

The cycles of concentration should be maximized. Increasing cycles from three to six reduces cooling tower make-up water by 20 percent and cooling tower blowdown by 50 percent.

Reducing your blowdown means less chemical use, which means a decrease in neutralizing the water. Reducing blowdown also means less water use. The above mentioned correlates a lower cost of operations while saving money on wastewater costs.

Your cooling tower water treatment specialist should work with you on maximizing the cycles of concentration. Many systems operate at two to four cycles of concentration, while six cycles or more may be possible. Talk to your water treatment specialist about the options available to you.
