What Is a Shallow Sand Filter?

A shallow sand filter is a compact, high-efficiency filtration system designed to remove suspended solids, sediments, and impurities from water. Unlike deep-bed sand filters, shallow sand filters have a lower bed depth, making them more efficient in backwashing while maintaining excellent filtration performance.

These filters are widely used in irrigation, wastewater treatment, swimming pools, industrial processes, and municipal water systems due to their simple design, low energy consumption, and easy maintenance.

Product Structure of Shallow Sand Filters

Our shallow sand filters are engineered with high-quality materials and a well-thought design for optimal performance. Key components include:

1. Tank (Pressure Vessel) – Made of fiberglass (FRP), stainless steel, or carbon steel with anti-corrosion coating, ensuring long service life.

2. Sand Bed – Filled with high-purity quartz sand or multimedia filter media to trap impurities.

3. Inlet & Outlet Ports – Designed for smooth water flow with minimal pressure loss.

4. Distribution System – Ensures even water distribution across the sand bed for uniform filtration.

5. Backwash System – Automatically or manually cleans the filter media, reducing maintenance efforts.

6. Control Valve (Optional) – Allows for automatic filtration and backwashing cycles.

How Does a Shallow Sand Filter Work?

The working principle is simple yet highly effective:

1. Filtration Process – Contaminated water enters through the inlet valve, passes through the sand bed, where impurities are trapped, and clean water exits through the outlet.

2. Backwashing Process – When the filter gets clogged, the flow reverses, flushing out trapped debris and restoring filtration efficiency.

3. Rinse Cycle (Optional) – Ensures no residual dirt remains before resuming normal filtration.

This automatic or semi-automatic operation makes our shallow sand filters energy-efficient and user-friendly.
