Sodium Hypochlorite Storage Tanks / Bleach Storage Tanks

  Double wall plastic tanks are an excellent choice for Bleach (Sodium Hypochlorite) storage.  Double wall tanks offer excellent secondary containment protection against spills of hazardous chemicals like Bleach (Sodium Hypochlorite) with a minimum footprint.
  Sodium Hypochlorite (Bleach) Storage Bleach (Sodium Hypochlorite) is a dangerous chemical to store and requires great care to store it safely.  One factor in safe storage of Sodium Hypochlorite is to provide secondary containment in case a spill takes place.  A double wall storage tank has secondary containment built in to the design. 
  Steel, Fiberglass or Poly?
Sodium Hypochlorite is a poor match for stainless steel tanks so one of the natural choices has been plastic storage tanks.  Polyethylene tanks hold much of the Bleach used by industry and water treatment operations today.
  There are differences in Polyethylenes?
When you start looking for the right Polyethylene tank for storage of Sodium Hypochlorite, things get a little tricky.  While resin maker Exxon has done studies with the University of Nebraska, some tank makers continue to go against recommendations from Exxon that result from that study.  As a result, you could be tricked into a bad choice of tank materials and end up getting a tank that has a shorter useful life than is otherwise available.
... High Density Polyethylene versus Crosslink Polyethylene.
There are several variations of Polyethylene.  The two that come into play with Sodium Hypochlorite are High Density Polyethylene and Crosslink Polyethylene.   Crosslink is an older type of polyethylene that is more expensive, not recyclable and is not ‘weld-able’ using thermoplastic welding.  It has advantages when it comes to the storage of a few chemicals but, according to Exxon, it is not the best choice for tanks that will store sodium hypochlorite.  Exxon’s study shows clear benefits from using HDPE (High Density Polyethylene) for the storage of Sodium Hypochlorite.

  Tank Location makes a difference!
Beyond the selection of High Density Polyethylene as the material for the tank, the planned location also affects tank details.
  Indoor:
Indoor Tanks where exposure to Ultra Violet rays will be low can be manufactured from Natural color resin.  It is a translucent white and since you can see the level of the liquid, there is no need for a sight gauge.
  Indoor Tanks where exposure to Ultra Violet rays will be moderate can be made from Black colored resin.  The fill level will not be visible so a sight gauge or other level indicator is a very good idea.
  Outdoor:
Outdoor tanks can be made from Natural color resin if they are going to be coated with polyurethane foam insulation and covered with a mastic coating.  Fill level is not visible through the foam.
  Outdoor tanks that will not be coated with insulation should be opaque.  Depending on the climate and degree of exposure to direct sunlight, either a black or opaque white tank could be suitable.
  What grade of tank?
Polyethylene tanks are manufactured and rated based on the weight per gallon of the liquid they are able to hold.   Beyond the weight of the liquid, other factors such as the effect of the chemical on the tank over time must be taken into account.   We recommend using tanks with a specific gravity of 1.9 or higher for storing Sodium Hypochlorite.
