Side Stream Filter for Cooling Towers – An Effective Solution for Maintaining Circulating Water Cleanliness

What is a Cooling Tower Side Stream Filter?

A Side Stream Filter is a filtration system that filters a portion of the water from the cooling tower circulation to remove solid particles, sludge, and contaminants before returning it to the system.

Without proper filtration, dirt will accumulate and cause:

• Nozzle & fill clogging → Reduced cooling efficiency.

• Scaling & corrosion → Faster component damage.

• Bacterial & algae growth → Risk of Legionella and health problems.

How Does a Side Stream Filter Work?

1️⃣ Partial Water Extraction (10%-15% of total flow rate)

Water from the cooling tower is pumped to the filter via a side stream pump.

2️⃣ Filtration Process

Contaminants such as sand, mud, metal particles, and organic matter are filtered out.

3️⃣ Returning Clean Water to the System

The filtered water is returned to the cooling tower, reducing the dirt load.

Functions & Benefits of Side Stream Filters

🔹 Prevents Fouling & Scaling → Maintains heat transfer efficiency.

🔹 Extends Component Life → Fillers, pipes, and heat exchangers last longer.

🔹 Reduces Chemical Treatment → Cleaner water = lower chemical requirements.

🔹 Saves Water & Energy → Minimizes blowdown & pump/fan load.

🔹 Controls Microbial Growth → Reduces the risk of Legionella and biofilm.

Why Use a Side Stream Filter?

Without Filtration:

❌ High Maintenance Costs – Frequent cleaning of fillers and nozzles.

❌ Unexpected Downtime – Disruptions due to blockages.

❌ Water & Chemical Waste – More frequent blowdown required.

With Side Stream Filter:

• More Stable Operation – Minimal fouling disruptions.

• Long-Term Cost Savings – Reduced damage & chemical usage.

• Maintained Water Quality – Cleaner water in the cooling tower.
