Sodium Hypochlorite Storage Tanks are manufactured from HDPE, XLPE, and FRP materials at 1.9 specific gravity. Secondary containment is required. Bleach is best stored out of direct sunlight, at temperatures below 60°F, filtered and diluted with pH kept above 10. Tank capacities range from 35 to 100,000 gallons.Suiting for custom chemical mixing.
Sodium hypochlorite should be stored separately from incompatible materials. Store chemicals such as reducing agents, organic materials and acids away from bleach. Sodium hypochlorite storage needs to be at temperatures below 68 F (20 C) in air-tight bottles.
For diverse manufacturing industries and plant operators, it is a challenge to store chemicals, acids, fuels, and gasoline in bulk quantities with safety.
It is especially difficult to keep corrosive and hazardous chemicals and acids because when spilled or leaked they can cause catastrophic accidents in an industrial site or workplace.
Sodium hypochlorite is one such chemical that needs to be dealt with care and stored properly in a vessel.
Also known as bleach and hypochlorous acid, the ionic compound with unique properties finds application in disinfecting water and cleaning purposes, sodium hypochlorite needs to be protected from UV solar rays, oxidation, and off-gassing.
• Fiberglass reinforced plastic storages, polyethylene storage tanks, and chlorobutlyl rubber-lined steel storages are the best choices for it.
Even high-density polyethylene tanks are also popular choices among the manufacturers because they are robust, durable and have a specific gravity of 1.9 to offer resilience to corrosion.
Fiberglass tanks are the best storage options for sodium hypochlorite if you are looking for a long-term investment.
It can last up to 15 years when properly designed, constructed, maintained, and installed. Polyethylene tanks are also viable options and they are as good as fiberglass tanks. They are known for their molecular weight and tensile strength.
• Tanks that are reinforced with linings are a feasible option for storing sodium hypochlorite. The linings will protect the container from getting exposed to corrosive activities of the solution that can lead to contamination of iron and structural damage.
• Besides linings, it is also essential to opt for corrosion-resistant and semi-flexible piping, fitting, and gasket materials to shield the chemical contents from sunlight, ozone, weathering, and permeation.
• Avoid steel storage tanks as they are incompatible with bleach. It is because they tend to degrade when the chemicals are stored in them.
• Tanks equipped with in-built secondary containment and catchment basin are especially useful. It will prevent the leakage of the hazardous chemical in bulk quantities.
It also acts as a backup when there is a tank failure. It is mandatory for the secondary containment to be chemically resistant and have the capacity to hold 110% of total system fluid capacity when the tank becomes loaded with contents.
• The storage system should be vented to prevent the accumulation of oxygen off-gassing of NaOCl. The size of the venting should be twice of the inlet pipe diameter.
• The best component materials for sodium hypochlorite storage tank comprise PVC/CPVC pipes and titanium encapsulated bolts. You can also consider PTFE, PVDF, FKM, and tantalum.
• While assessing the storage vessels, it is important to keep in mind the concentration strength of the chemical compound.
