Water purification (Goldsmith plants)

Clean water treatments 

The water purification system is essential for eliminating salt from water throughout demineralisation using resins (cationic or anionic exchangers). Water is transported in a cationic exchanger and then goes through an anionic exchanger to obtain clean water, which is thus used for cleaning the treated metals. 

Wastewater treatments 

Wastewater used during refining processes can be cleaned to be reused or released into the atmosphere with no toxicity. Goldsmith plants are equipped with wastewater treatment systems to clean up the waste particles from water. Wastewater is transferred along with detergent solutions throughout magnetic centrifugal pumps: it is filtered and cleaned from polluted agents.
