Self Cleaning Wedge Wire Filter for Cooling Tower Wastewater Treatment

Posted by YUBO Filtration on August 8th, 2024

Cooling towers are essential in heat exchange processes for industrial and commercial operations. However, the efficient functioning of these towers comes with the challenge of managing and treating the wastewater they generate. Self-cleaning wedge wire filters offer a robust solution for maintaining water quality and ensuring optimal cooling system performance.

The Challenges of Cooling Tower Wastewater Treatment:

Cooling tower wastewater can contain a wide range of contaminants, including:

Suspended solids (e.g., dirt, debris, and biological matter)

Bacteria and other microorganisms

Scale-forming minerals (e.g., calcium and magnesium)

Corrosion byproducts (e.g., iron and copper)

Chemical additives (e.g., biocides and corrosion inhibitors)

These contaminants can lead to:

Reduced heat transfer efficiency

Increased energy consumption

Premature equipment failure

Environmental harm (e.g., water pollution and harm to aquatic life)

The Solution: Self-Cleaning Wedge Wire Filters

Self-cleaning wedge wire filters feature a unique, vee-shaped wire design that provides exceptional contaminant removal efficiency and self-cleaning capabilities.

The wedge wire screen is designed to capture fine particles with precision. The narrow slots between the wires effectively trap contaminants while allowing clean water to pass through.

How Self-Cleaning Wedge Wire Filters Work

Wastewater flows into the filter, where contaminants are trapped by the wedge-shaped wire design.

As the filter becomes clogged, the pressure differential across the filter increases.

When the pressure reaches a predetermined level, a small amount of clean water is injected into the filter, reversing the flow and dislodging the trapped contaminants.

The contaminants are then flushed out of the filter, restoring its original efficiency.

Key Benefits of Self-Cleaning Wedge Wire Filters

High Filtration Efficiency

Automatic Self-Cleaning

Maintain Optimal Heat Transfer Efficiency

Reduce Maintenance Costs and Downtime

Application Case 

Traditional mesh filters are widely used in the textile manufacturing factory wastewater treatment industry. They remove textile waste before the water enters the cooling tower. However the filters are often blocked, and some textile waste will pass through the cooling tower and block the inside of the cooling tower.

The self-cleaning wedge wire filter or self-cleaning filter replaces the traditional mesh filter. It greatly improves efficiency and reduces maintenance costs and downtime.
