Why Demister Pads Block & Foam Separation Fails

Symptoms · Root Causes · Proven Solutions

Dust and sticky foam block wire mesh, increasing resistance, reducing gas volume and allowing foam and mist to escape from the tower.

The Problem

What Is Happening?

Dust and sticky foam block wire mesh, increasing resistance, reducing gas volume and allowing foam and mist to escape from the tower.

Common Symptoms

  • System pressure drop rises sharply
  • Exhaust flow and handling capacity fall
  • Foam and mist overflow from the tower top
  • Local blockage creates uneven airflow
What Is Happening?
Root Causes

4 Root Causes

01

Viscous Foam Deposition

Sticky substances form dense deposits in mesh openings.

02

Fine Powder Accumulation

Deep dust buildup cannot clear under normal airflow.

03

Corrosion & Deformation

Broken or distorted mesh loses separation efficiency.

04

Wrong Mesh Density

Excess density blocks easily; low density misses fine droplets.

Proven Solutions

3 Recommended Actions

Solution 01

Customize Mesh Specification

Match density, thickness and material to foam, particles and corrosion.

Solution 02

Use High-Pressure Washing

Flush deposits regularly to restore ventilation.

Solution 03

Upgrade Mesh Material

Use corrosion-resistant, anti-clogging woven structures.
