The carbon steel multi-media filter is a core pre-treatment equipment for industrial water treatment systems. Made of high-quality carbon steel with anti-corrosion coating, it is filled with multiple filter media such as quartz sand, anthracite and activated carbon. Through multi-layer gradient filtration, it effectively removes suspended solids, colloids, sediment, rust, residual chlorine, organic matter and heavy metals, reducing turbidity and pollution index to ensure stable inlet water quality for subsequent processes like reverse osmosis, softening and pure water preparation. Widely used in industrial circulating water, sewage treatment, municipal water supply, chemical, food, pharmaceutical and power industries.

+86 15936525232Efficient Multi-effect Purification: Multi-layer gradient filter media design achieves both physical interception and adsorption, reducing turbidity to ≤1NTU and removing over 99% of suspended solids.
Durable Carbon Steel Tank: Made of Q235 carbon steel with anti-corrosion coating, pressure-resistant and corrosion-resistant, suitable for complex industrial conditions with a service life of over 10 years.
Low Operation & Maintenance Cost: Runs by water pressure with no extra energy consumption. Equipped with automatic/manual backwash system, simple operation and low maintenance cost.
Compact & Versatile: Vertical/horizontal design with small footprint. Customizable filter media combinations to adapt to different water quality and treatment scales.
Automatic Operation: Optional PLC control system realizes full-process automatic filtration, backwashing and rinsing, suitable for unattended industrial scenarios.
Water enters the tank from the top and flows down through the multi-layer filter bed:
Coarse filtration layer (upper): Intercept large particles, sediment and rust, reducing inlet turbidity.
Medium filtration layer (middle): Remove colloids and suspended solids for further purification.
Fine filtration layer (lower): Adsorb residual chlorine, odor and organic matter to improve water stability. When the filter media is saturated, backwashing (water backwashing + air scouring) is performed to discharge trapped impurities and restore filter performance, enabling long-term cyclic operation.
