Treatment of pit wastewater from coal mining

Pit groundwater from coal mining in Vietnam is heavily polluted by high solids loads as well as high concentrations of iron and manganese. As the wastewater is not treated in any way, the outfalls are polluted. The project partners therefore develop a new, innovative pit water purification system allowing the national limit values for wastewater to be met.
