Preserving quality of life
Our gases help to identify and eliminate pollutants, re-use raw materials and conserve resources.
Oxygen - the elixir for waters.
In biological sewage treatment, the microorganisms need oxygen for respiration. The SOLVOX® process from Linde selectively introduces pure oxygen into wastewaters and thereby considerably enhances the cleaning efficiency of sewage-treatment plants.
Nitrogen compounds that do not degrade in sewage-treatment plants cause excessive algae growth, and so temporarily deplete oxygen levels in surface waters. The SOLVOX® process also helps restore the self-cleansing power of the waters and, prevents fish from being killed.
Further areas of application for pure oxygen are:
- Wastewater transport
- Drinking water processing
- Intensive fish farming
Life-giving air
Industrial manufacturing processes often generate volatile organic compounds, which contaminate the air. The coldness of liquid nitrogen can be utilised to condense them. This non-polluting method is especially economically attractive when the pollutant concentrations are so high that they can be reused after condensing.
