Salt Separation and Recovery
What is Valuable Resource Recovery?
To reuse and recycle the brine or salt more effectively to reduce the waste or pollution:
- Valuable salts recovery from wastewater
- Brine extraction
- Salt solution after ore
Resource recovery is the trend of environmental protection and sustainable development. It not only helps to reduce environmental pollution, but also can improve the efficiency of resource utilization. It is an important way to achieve sustainable development and environmental protection.
Through our technolog, to extract high-purity brine or salt crystals while significantly reducing the waste.
Valuable Salts Recovery in Sanfeng Tech
In our industry, valuable resource recovery refers to recovering valuable or reusable salts and metals from different stream. According to our rich engineering experience, Sanfeng has the practice in recycling below salts:
- Magnesium sulfate heptahydrate (MgSO4.7H2O)
- Calcium chloride (CaCl2)
- Sodium sulfate (Na2SO4)
- Sodium chloride (NaCl)
- Ammonium sulfate (NH42SO4)
- Sodium nitrate (NaNO3)
- Ammonium chloride (NH4Cl)
- Lithium hydroxide (LiOH)
Technical Process in Brine OR salt recovery
- Membrane technology
- Ion exchange
- Biological treatment
- Advanced oxidation process
- Thermal evaporation and freezing separation
- Drying and packing
Evaporation is to recover one or more kinds of salts from wastewater. As the final step of zero liquid discharge, evaporation is also the most important section. On the one hand, after evaporating the water, the condensate can be reused, on the other hand, the separated two or more kinds of salts can meet the standards for sale, creating profits for the enterprise.
Our Advantages
