Heat pump cold crystallization system, where the process solution is cooled down to -10°C in a reactor with an internal mixer and external jacket where the primary cooling fluid circulates (Freon gas). The salts that have formed inside the reactor are discharged in semi-continuous mode into draining bags, the drained mother liquor is sent to the process line or brought back into the crystallization reactor.
Advantages:
- Recovery of raw materials from spent process solutions
- Turning concentrated liquid waste into "dry" waste
- Filtration of galvanizing baths (decarbonation, sulphuric acid regeneration)
Application area:
- Electroplating and Galvanizing
- Powder coating
- Photovoltaic, electronics and semiconductors
