Low levels of inorganic phosphate are very effective at corrosion inhibition however, using this type of program under inappropriate water and plant conditions can result in severe scaling. This paper will discuss the basic selection / application criteria that need to be applied to avoid deposition problems. A number of case histories will be used to illustrate why this type of program can fail in industrial settings.
