What Makes Our Shallow Sand Filters Stand Out?

Unlike conventional sand filters, our shallow bed design offers:

✔ Faster filtration & easier backwashing

✔ Lower pressure drop & energy consumption

✔ Compact footprint – ideal for space-limited installations

✔ Longer lifespan with premium corrosion-resistant materials

In-Depth Look: Design & Construction

Our filters are built with precision using:

1. Robust Tank Construction

Material Options: FRP (fiberglass), stainless steel, or epoxy-coated carbon steel

Pressure Rating: Standard 6-10 bar (custom high-pressure models available)

2. Advanced Filtration Media

High-grade quartz sand (0.4-1.2mm grain size)

Optional multi-layer media (anthracite, garnet) for enhanced filtration

3. Smart Flow Distribution System

Patented lateral pipe design ensures even water distribution

Prevents channeling for consistent filtration efficiency

4. Low-Maintenance Backwash System

Automatic or manual operation

50% less water used vs traditional sand filters

How It Works: Simple Yet Highly Effective

1. Filtration Phase

Untreated water enters through the inlet valve

Flows downward through the sand bed, trapping suspended solids

Clean water exits through the bottom collector system

2. Backwash Cycle (Automatic/Semi-Auto)

Flow reverses to expand and fluidize the sand bed

Trapped contaminants are flushed to drain

Rinse cycle re-stratifies media before returning to service

Filtration Accuracy: 20-50 microns (customizable)

Key Advantages Over Competitors

✅ 30% Faster Filtration – Shallow bed allows higher flow rates

✅ Self-Cleaning – Minimal manual intervention required

✅ Corrosion-Resistant – Suitable for seawater & harsh environments

✅ Modular Design – Easy to scale for large capacities

✅ Energy Efficient – Low power consumption vs deep bed filters
