High-Quality Shallow Sand Filters: Your Trusted Water Filtration Solution

Introduction

As an experienced manufacturer specializing in shallow sand filtration systems, we take pride in delivering durable, efficient, and cost-effective solutions for water treatment across industries. With years of expertise in production and customization, our filters are designed to meet the highest standards of performance and reliability. This article provides an in-depth look at the working principle, key benefits, industry applications, and technical specifications of our premium shallow sand filters.

How Shallow Sand Filters Work

Shallow sand filters operate on a simple yet highly effective multi-layer filtration mechanism:

1. Inlet Distribution – Water enters the filter through an inlet valve, evenly distributing across the sand bed.

2. Filtration Process – As water flows downward, the graded silica sand media (0.4–1.2 mm) traps suspended solids, organic matter, and fine particles.

3. Clean Water Outlet – Filtered water exits through the underdrain system, ready for use.

4. Automatic Backwashing – When pressure builds up, the system reverses flow to flush out trapped impurities, restoring filtration efficiency.

Our filters support manual, semi-automatic, or fully automatic control, ensuring flexibility for different operational needs.
