Product Description：        Metallurgical processes generate waste oil/water from equipment cooling (70% of total), flue gas washing, and site cleaning. Indirect cooling water recycles directly post-cooling. Direct cooling water—containing pollutants, dust, and metal particles—requires sedimentation, purification, and precision filtration before reuse. Our system uses multi-layer composite media to trap 0.5-100μm solids/colloids, achieving <5NTU turbidity with chemical flocculation pretreatment, meeting industrial recycling standards.
