Enabling solutions for municipal and industrial water treatment needs

With the relentless growth of urban centers worldwide and the continuous use or water in a broad range of industrial processes, the availability of reliable chemistries for water treatment is more important than ever. Because of their purity and consistency, BASF's inorganic salts are key ingredients in both well-established solutions for water treatment, as well as for new emerging technologies.

Examples of applications include:

Sodium Metabisulfite and Sodium Bisulfite Solution

  • Control of excess chlorine in water treatment processes
  • Maintenance of reverse osmosis membranes in water desalination
  • Production of cleaning products

Sodium Sulfite

  • Oxygen scavenging agent for the pre-treatment of water for steam boilers
  • Control of excess chlorine in water treatment processes

Ammonium Bicarbonate

  • Precipitation of rare-earth elements
  • Forward direct osmosis for desalination

Ferric Chloride

  • Flocculant and coagulant
  • Dehydration of sewage sludge
