Shallow Sand Filters: Efficient Filtration Solutions for Various Industries

Introduction

As a leading manufacturer of filtration systems, we specialize in producing high-quality shallow sand filters with years of expertise in design and production. Our filters are widely used in industrial, commercial, and municipal applications, providing reliable and cost-effective solutions for water treatment. In this article, we will explore the applications, technical parameters, usage, features, and advantages of our shallow sand filters.

Applications of Shallow Sand Filters

Shallow sand filters are versatile and suitable for multiple industries, including:

1. Municipal Water Treatment – Used for filtering drinking water, swimming pools, and wastewater treatment.

2. Industrial Processes – Effective in removing suspended solids from process water in food & beverage, pharmaceuticals, and chemical industries.

3. Agriculture & Irrigation – Prevents clogging in drip irrigation systems by filtering out sand, silt, and organic matter.

4. Aquaculture – Maintains clean water in fish farms by removing impurities.

5. Commercial Buildings – Used in HVAC systems and cooling towers to improve water quality.

Technical Parameters

Our shallow sand filters are designed for high efficiency and durability. Key specifications include:

1. Filtration Media: High-grade silica sand (0.4-1.2 mm grain size)

2. Flow Rate: 10-100 m³/h (customizable based on requirements)

3. Operating Pressure: 2-6 bar

4. Filtration Accuracy: 20-50 microns

5. Tank Material: FRP (Fiberglass Reinforced Plastic), stainless steel, or carbon steel with epoxy coating

6. Backwash System: Automatic or manual, with low water consumption

How Shallow Sand Filters Work

The filtration process consists of three main stages:

1. Filtration – Water passes through the sand bed, trapping suspended particles.

2. Backwashing – When pressure increases, the system reverses water flow to clean the sand bed.

3. Rinsing – After backwashing, clean water flushes out remaining debris before resuming normal operation.

Our filters can operate manually or automatically, depending on the control system (timer-based or differential pressure-triggered).

Key Features of Our Shallow Sand Filters

1. Compact & Lightweight Design – Requires less space compared to deep-bed sand filters.

2. Low Maintenance – Simple structure with minimal moving parts reduces servicing needs.

3. High Filtration Efficiency – Removes fine particles effectively with consistent performance.

4. Corrosion-Resistant Materials – FRP or stainless steel construction ensures long service life.

5. Energy-Efficient Backwash – Uses less water and power compared to traditional systems.

Advantages Over Other Filtration Systems

1. Cost-Effective – Lower initial investment and operational costs than multimedia or cartridge filters.

2. Easy Installation & Operation – No complex setup; suitable for small and large-scale applications.

3. Environmentally Friendly – No chemicals required; only backwash water is needed for cleaning.

4. Scalable Solutions – Can be used as a single unit or in multi-tank configurations for higher flow rates.

Conclusion

Our shallow sand filters provide reliable, efficient, and economical filtration for diverse industries. With years of manufacturing expertise, we ensure high-quality products tailored to meet specific customer needs. Whether for municipal water treatment, industrial processes, or agricultural irrigation, our filters deliver superior performance with minimal maintenance.
