The concentration process is mainly used in the chemical industry to separate an evaporated liquid from a salt solution.
The most common applications treat the following waste streams:
• Inorganic acid solutions
• Solvent solutions containing salts
• Organic solutions with dissolved salts
• Caustic soda solutions
Recovering these solutions helps reduce disposal costs, which are otherwise high due to the nature and volume of the waste.
It also allows for the reuse of the waste in other sectors.
In our plants, the aqueous solution of ferrous chloride undergoes the following processes:
• Treatment in an oxidation plant, with the goal of producing ferric chloride by oxidizing it with sodium chlorate powder.
• The resulting aqueous ferric chloride (FeCl₃ ~ 25%) is then treated in the concentration plant and reused for water treatment in civil purification plants installed in cities and industrialized countries.
