Titanium Storage Tank For Sodium Hypochlorite / Hypochlorous Acid NaOCl

Titanium Storage Tank For Sodium Hypochlorite

Sodium hypochlorite, also known as bleach and hypochlorous acid, is a strong oxidizer of ionic compounds with unique properties that can be used for water disinfection and cleaning purposes. How to store them safely is a challenge because when spilled or leaked, they can cause catastrophic accidents in industrial sites or workplaces. Sodium hypochlorite requires protection from UV rays, oxidation and outgassing.

There are three factors to consider when storing sodium hypochlorite;
1. Ultraviolet light can degrade sodium hypochlorite, so special precautions must be taken to reduce this effect.
2. Sodium hypochlorite usually contains transition metals such as nickel, iron and copper, which can accumulate in storage tanks and generate exhaust gas. Sodium hypochlorite is compatible with only a small subset of metals, including titanium, platinum,gold, silver, and tantalum. All other metals cause contamination of the NaOCl solution, which results in product decomposition and increased oxygen production. Stainless steel, copper, brass, Hastelloy and Monel metals should be avoided in NaOCl applications.Copper is probably the most notable on this list due to its increased use in industrial plumbing. Copper tubing can cause elemental copper (Cu 2+ ) to contaminate NaOCl solutions and cause a significant increase in product degradation.
3. Consider the corrosion resistance of the tank material.
Commonly used sodium hypochlorite storage tanks are the following four types. Among them titanium is the most ideal solution.
