【Mine water refilling】

Case background: In order to reduce the impact of mine water on surface water, coal mine companies need to refille the treated mine water underground.

Application process: After pretreatment (such as precipitation, filtration), the mine water enters the reverse osmosis system. The reverse osmosis membrane can effectively remove dissolved salts, heavy metal ions and organic matter from the water. After the water production reaches the re-injection standard, it will be refilled to the ground through the water injection well.

Application effect: The application of reverse osmosis membrane improves the quality of mine water reflux, reduces pollution to groundwater resources, and realizes the recycling of water resources.
