Focus #3: Water quality

Our products: essential ingredients for water treatment

How can we help improve water quality?

Some of the various processes that can be used in water treatment involve ingredients produced by Humens:

  • Sodium carbonate and sodium bicarbonate, which help stabilize water pH.
  • Sodium carbonate, which reduces water hardness by precipitating calcium.
  • Sodium silicate, which is used for water treatment, particularly for its anti-corrosive properties to protect drinking water pipes, as well as for its capacity to precipitate certain metals such as iron and aluminum.

Other applications that are beneficial for the environment also use our products. For example, sodium bicarbonate is used to purify flue gases in combustion plants, including household waste incinerators and thermal power plants.
