Industrial Backwash Filters

Introduction

In today’s competitive industrial landscape, optimizing filtration systems is no longer optional—it’s essential. As a leading backwash filter manufacturer, we’ve engineered cutting-edge self-cleaning solutions that outperform traditional filters in efficiency, reliability, and total cost of ownership. This comprehensive guide explores why industries worldwide are switching to backwash technology.

Why Traditional Filtration Systems Fall Short

Many facilities still rely on outdated filtration methods, unaware of the hidden costs:

✔ Bag/Cartridge Filters

Require frequent manual replacements

Generate hazardous waste (spent filters)

Cause production downtime during changes

✔ Sand Filters

Inefficient backwashing (30-40% water waste)

High maintenance (media replacement every 3-5 years)

Limited filtration accuracy (50+ microns)

Our Solution: Fully automated backwash filters that deliver continuous operation, zero disposable waste, and superior filtration precision.

How Our Backwash Filters Work: A Step-by-Step Breakdown

1. Filtration Phase

Contaminated fluid enters the filter vessel.

Solids are trapped on the high-grade stainless steel screen (options: 20–3000 microns).

Clean fluid exits the system.

2. Clog Detection

Differential pressure sensors monitor screen blockage.

When ΔP reaches a setpoint (e.g., 0.5 bar), backwash initiates.

3. Self-Cleaning Backwash

A rotating suction scanner or reverse flow valve activates.

Debris is flushed out in <15 seconds without stopping flow.

Waste is discharged to drain or recovery system.

4. Resumption of Service

The filter returns to full operation immediately.

No human intervention required.
