Demineralised Water Tanks

Demineralised water has many uses but requires special tanks to store it safely since it can be very aggressive towards metal containers. Here we look at exactly what it is, where it is used and how to store it safely.

Demineralised water (also known as Demin or demi) is water that has its minerals removed. It may still contain organic impurities like bacteria and viruses, and further treatment may be needed to remove them if necessary. But here is a list of metals that are removed:

  • Calcium
  • Iron
  • Magnesium
  • Manganese
  • Chlorides
  • Nitrates
  • Sulphates
  • Sodium
  • Potassium
  • Fluoride

This results in very soft water that has a very low conductivity – less than 2mS/m.

Demineralised Water Tanks

The Demin water is also very quick to pick up minerals wherever it can – so it is very aggressive towards metal containers and pipes.

Enduramaxx tanks are made from the highest-grade plastic material, so they are ideal for storing demineralised water. Our tanks are rotationally moulded so there are no seams or joints. They are tough and long-lasting and can withstand prolonged outdoor or indoor use.
