Why add EDTA?
Caustic is a very effective cleaning agent. It’s particularly useful to dissolve organic matter and it’s used in many industries dealing with such residues, including breweries, distilleries and others. In addition, caustic soda has some antibacterial properties, which is an added bonus in this type of environment.
However, caustic soda used alone can become problematic in areas with hard water. Under alkaline conditions, caustic soda promotes the precipitation of carbonate and other salts, which may affect the entire plant with a whitish film left on every surface after cleaning.
This problem can be solved by the addition of EDTA (Ethylene Diamine Tetra-acetic Acid) to the cleaning solution, effectively keeping carbonate, as well as calcium and magnesium-containing salts dissolved. However, EDTA cannot prevent formation of scale, when its main component are silica-based compounds. Other compounds with similar properties include sodium hexametaphosphate or sodium gluconate.
This is only one of the many different types of additives which can be added to caustic soda to enhance its cleaning properties. Examples include metasilicates, phosphates and surfactants to disperse and maintain in solution both organic and inorganic compounds.
