Water & Sewage Treatment

Image module

Industries must reduce their pollution emissions and improve their processes for maximum reuse of water and materials, while complying with the reinforcement of environmental and sanitary regulations. At Air Liquide, we master applications using gas technology to treat water, recycle metal, recover solvents, analyse air quality and recover waste.

Industries must reduce their polluting emissions, improve their processes for a maximum reuse of water and materials.

  • Drinking Water: Carbon dioxide (CO2) is used for calco-carbonic equilibrium management for remineralization and pH control at desalination plants. Advanced treatment processes to answer stringent regulatory standards require oxidation and disinfection properties of oxygen and ozone.
  • Wastewater: The introduction of pure oxygen into biological basins with gas injectors, instead of using the traditional air blowing technology, helps industries comply with today’s strict regulations regarding waste-water discharge.
  • Sludge Reduction With innovative ozone solutions developed by Air Liquide, the biological sludge production and the energy and consumption of reactive products are reduced. Our customers manage their activated sludge process in a more efficient manner and produce 30% to 40% less sludge.
  • Scaling Treatment Replacing liquid chemical acids with the dissolution of carbon dioxide in cooling water helps prevent or eliminate scale in the cooling circuits. Our expertise allows us to provide the most adapted treatment based on water characteristics and chemical treatments.
