Description and Use


Safe Acid Powder is an acidic cleaner which is specifically designed to remove calcium carbonate, calcium phosphate or zinc phosphate deposits from metal surfaces. For aluminium surfaces use “Safe Scale Remover“.



Typical Applications

Safe Acid Powder is designed to remove calcium and zinc based deposits, particularly calcium carbonate scales, from plant equipment. The rate of removal of deposits is accelerated when the cleaning solution is heated and maintained at a temperature in the order of 60°C. Safe Acid Powder should not be used in equipment constructed in, or containing, galvanised steel or zinc.
After cleaning, equipment should be thoroughly rinsed with water and then rinsed with a neutralising solution such as sodium carbonate solution, and then thoroughly rinsed with water again.. Do not leave equipment wet or damp after cleaning as “after rusting” may occur.
Safe Acid Powder contains an indicator which shows when the cleaning solution is nearing exhaustion and needs replenishing. When freshly prepared the cleaning solution will have a reddish purple color. When about 80% exhausted, the colour will turn to orange and when completely exhausted the colour of the solution will be yellow. As the cleaning solution becomes progressively exhausted it should be replenished by adding more Safe Acid Powder. Cleaning is complete when the cleaning solution show no further colour change over a period of 30 minutes when used at 60°C, or 2 hours when used at ambient temperature.



Treatment and Feeding Requirements


Proper treatment levels of Safe Acid Powder depend on many factors, such as quantity, composition and nature of deposits and conditions particular to a given installation. Typically the product would be applied at a solution concentration of between 5% and 10% of Safe Acid Powder. The product should be used in accordance with control procedures that GE Water & Process Technologies establishes for a specific application.
