Introduction
In an era where clean water is critical for industrial, commercial, and municipal applications, our factory-direct multi-media filters stand out as a premium yet cost-effective solution for global buyers. As a trusted Chinese manufacturer specializing in filtration systems, we combine advanced engineering, durable materials, and smart design to deliver filters that outperform competitors.
Whether you need pre-treatment for RO systems, wastewater clarification, or process water purification, our multi-media filters provide unmatched efficiency, longevity, and value. Here’s why international clients choose us:
How Our Multi-Media Filters Achieve Superior Filtration
Unlike single-media filters, our systems utilize a stratified bed of multiple filtration media (typically anthracite, silica sand, and garnet) to capture impurities at different levels. This multi-stage trapping mechanism ensures:
1. Higher dirt-holding capacity – More contaminants removed before backwashing is needed.
2. Longer filtration cycles – Reduced downtime and maintenance costs.
3. Finer particle removal – Effective down to 10-15 microns, ideal for pre-treatment before membrane filtration.
Process Flow:
1. Influent water enters the filter vessel.
2. Larger particles are trapped in the top anthracite layer.
3. Medium-sized particles are filtered by the middle sand layer.
4. The finest impurities are captured in the garnet or supporting gravel bed.
5. Clean water exits through the bottom collector system.
6. Automatic backwashing (when equipped) reverses flow to flush out trapped debris.
Key Advantages That Set Our Filters Apart
✅ Higher Flow Rates – Optimized media grading allows faster filtration without sacrificing efficiency.
✅ Extended Media Life – High-quality anthracite and garnet resist breakdown, saving replacement costs.
✅ Low Energy Consumption – Gravity-driven design minimizes pumping needs.
✅ Versatile Configurations – Manual, semi-automatic, or fully automatic control options.
✅ Corrosion-Resistant Materials – FRP, epoxy-coated carbon steel, or stainless steel tanks for harsh environments.
Built to Last: Rugged Construction & Smart Design
We don’t cut corners—our filters are built for decades of reliable service:
1. Tank Options:
FRP (Fiberglass Reinforced Plastic): Lightweight, ideal for saline or chemical-heavy applications.
Carbon Steel with Epoxy Lining: Heavy-duty for industrial plants.
Stainless Steel (304/316): For food, pharmaceutical, or ultra-pure water needs.
2. Precision Media Support System:
Stainless Steel Lateral Underdrains – Even distribution during filtration and backwash.
Nozzle Plates or Graded Gravel Base – Prevents media loss and channeling.
3. Optional Automation:
PLC-Controlled Valves – For timed or differential pressure backwashing.
Remote Monitoring – Integrates with SCADA systems.
