A New Practical Index For Predicting Safe Maximum Operating Cycles Of Concentration In Ozonated Cooling Towers

Abstract: A new useful index for predicting the maximum safe operating cycles of concentration in ozonated cooling systems is reported. This index utilizes simple, easily obtainable makeup water quality parameters including conductivity, alkalinity, calcium and magnesium hardness, chloride, and sodium and is easily calculated. The index provides greatly improved correlation with real-world-derived scaling tendencies in ozonated cooling systems compared to conventional scaling indices such as the Langelier Saturation Ind… Show more

“…Pryor and Fisher (1993) 23) have proven that conventional indices (for example, LSI) are used to forecast calcium carbonate precipitation in the waters of conventionally treated cooling towers, rather than as precise indicators of potential scale in the ozonized system. Using a practical approach, Practical Ozone Scaling Index (POSI), the POSI equation predicts the upper limit of conductivity operations in other ozonated systems 23) . The use of conventional indices cannot accurately predict how many cycles can be operated before scale concentration begins to build up in the ozonated cooling system.…”
