Iron and carbon dioxide removal by physical/chemical processes - Water and Wastewater

Carbon dioxide, iron and manganese salts are unwanted substances in drinking water. Often stripping processes are used to remove those. 2H MASSdek structured packings offer important advantages for stripping columns compared to random packings.


Why are carbon dioxide, iron and manganese found in water?

Rain and surface water dissolve various minerals and carbonates on its way through the soil before it forms ground water. As a result, the water contains low to high concentrations of iron- and manganese salts and carbon dioxide depending on the soil composition.

Aeration is one process step in ground water treatment to strip excessive carbon dioxide and other gaseous substances to prevent corrosion effects. It is mostly done in stripping columns filled with structured or random packings to generate a large contact surface between stripping air and the ground water.

ENEXIO supplies various structured packings with large geometric surfaces for an effective stripping performance. Due to the enormous hydraulic capacities of our 2H MASSdek® packings, very high water loading rates of more than 100 m³/(m²*h) are possible.

Structured packings for a higher service lifetime

By aeration a large amount of oxygen is solved in the water. This leads to an oxidization of iron- and manganese salts and creates insoluble iron- and manganese hydroxides with a potential risk of clogging effects.

ENEXIO 2H MASSdek structured packings are developed for such high process demands. Their

  • very high mechanical stability and
  • the high void spaces assure
  • longer service life times

than conventional random packings of equal stripping performance.
