Question: What is the definition of "good" cooling tower water?
Keywords: cooling,tower,water,content,chemistry,chloride,sulfate
Answer: Generally speaking, cooling tower water should have a pH between 6 and 8, a chloride content no more than 750 ppm, a sulfate content (SO4) below 1200 ppm, and a sodium bicarbonate (NaHCO3) content below 200 ppm. Additionally, cooling tower water should not be heated past 120 ??F to avoid plating out of treatment chemicals in process coolers.
Also, if free chlorine is used for biological growth control, it should be added intermittently with a free residual not to exceed 1 ppm and this should be maintained for short periods.
