Mine Wastewater Treatment

Mine Wastewater Treatment

The core of the scheme adopts the principle of natural osmotic pressure difference-driven separation. The entire process operates at normal temperature and near normal pressure without pressure increase, and no high-pressure booster equipment is required. The separation of water molecules is achieved through the osmotic pressure difference between the two sides of the membrane. It can efficiently retain suspended mud, heavy metal ions, hardness salts, colloidal particles, and residual beneficiation reagents in the mine wastewater, effectively preventing the irreversible clogging and scaling failure caused by traditional high-pressure membrane compression. The system has extremely strong resistance to shock, high salt content, and complex water quality. It can perfectly adapt to the harsh operating environment of the mine wastewater with large fluctuations in volume and quality, and multiple types of impurities, as well as unstable working conditions. It can maintain stable separation flux and treatment effect over a long period of time.
