In-Mine Source Solid-Liquid Separator Exclusively developed for coal mine downhole conditions, this device focuses on source-side governance. Featuring an integrated in-situ design adapted to narrow spaces, it enables direct solid-liquid separation in coal mining faces and drivage faces. It efficiently separates coal slurry and water without chemicals, fundamentally solving problems such as drainage channel clogging, sump silting, pump wear, and motor overheating. It resolves a series of mine water safety production challenges caused by high pollutant content. UF2-21 Series High-Throughput PVDF Membrane Customized for raw water characteristics in coal mines, this high-throughput, high-stability turbidity removal membrane operates without chemicals or coagulation processes. With a membrane flux 3 times higher than conventional products, it boasts excellent anti-fouling performance and long-term stable operation. It serves as the core preferred component for upgrading ultrafiltration/MBR systems.
