Challenges in Mine Water Treatment and the Advantages of Jozzon Products
The core difficulty of mine water treatment
1.High Mineralization
TDS often exceeds 3000 mg/L, and in some areas it reaches as high as 10000 mg/L.
2.High Hardness
High Ca²⁺ and Mg²⁺ content, prone to scaling.
3.High Sulfate Concentration
High SO₄²⁻ concentration, which reacts with Ca²⁺ to form CaSO₄, making traditional membranes highly susceptible to fouling.
4.Large Fluctuations In Water Quality
Water quality varies significantly across different mining areas and seasons.
5.Zero Emission Pressure
Salt content emission limit ≤1000mg/L, by-product salt must be recycled.
