Site water neutralisation with gases

Construction Site water alkalinization and pH setting

GAS APPLICATIONS

A safe and economical neutralization of alkaline wastewater is carried out with carbon dioxide (CO2). The environmentally friendly carbon dioxide prevents acidification and increased salt content of the water.

Advantages of CO2 over mineral acids

  • Safe and easy pH control; Acidification is not possible
  • No handling of dangerous, aggressive acids
  • no increase in salinity;
  • Prevents corrosion when reusing treated wastewater
  • no investment costs
  • low operating costs
