Industrial Case Study

Advanced Biocide Technology for Cooling Water Treatment

How ChloroKlean Plus eliminates biofilm and controls Legionella in cooling tower systems

The Challenge: Poor Microbial Control

Poor microbial control in cooling water systems not only raises Health & Safety concerns but also significantly impacts on the rate of corrosion, fouling and energy consumption.

Microbial Colonisation & Biofilm

Unchecked microbes colonise water systems, creating biofilm - a gel-like protective medium that shields bacteria from biocides.

Pitting Corrosion Under Biofilm

Under biofilms, low oxygen conditions allow certain bacteria to metabolise metals, causing highly damaging pitting corrosion to system components.

Heat Transfer Impairment

Biofilm is more insulating than mineral scale, significantly impacting heat transfer and resulting in high energy usage and operating costs.

Legionella Health Risk

Pathogenic bacteria such as Legionella can multiply in cooling water circuits under the right conditions, posing serious health and safety concerns.

The Solution: ChloroKlean Plus Technology

ChloroKlean Plus chemical technology offers mixed oxidising, highly effective broad-spectrum biocides for controlling micro-organisms in a variety of cooling systems.

1

Mixed Oxidising Biocide Technology

ChloroKlean Plus provides highly effective broad-spectrum biocides that control micro-organisms including bacteria, Legionella pneumophila, viruses, and biofilm.

2

Stable Inert Formulation

The biocides are provided as stable, inert formulations that create active chlorine and chlorine dioxide in solution when added to water.

3

In-Situ Chlorine Dioxide Generation

ChloroKlean Plus forms chlorine dioxide as part of the system water chemistry, not as a dissolved gas - a distinct advantage over traditional generators.

Key Benefits

Longer Residual Biocide

Unlike generated chlorine dioxide which is gassed off over cooling towers, ChloroKlean Plus residual lasts longer in the system.

Reduced Chemical Usage

Less chemical is needed to control bacteria effectively, reducing operational costs and environmental impact.

Comprehensive Protection

Suitable for open recirculating cooling towers, once-through systems, closed loop chilled water, air washers, and spray cooling systems.

Suitable Applications

Open Recirculating Cooling Towers

Once-Through Systems

Closed Loop Chilled Water

Air Washers

Spray Cooling Systems

"ChloroKlean Plus forms chlorine dioxide as part of the system water chemistry, not as a dissolved gas. This is a distinct advantage over generated chlorine dioxide as it is not gassed off over the cooling tower, meaning residual biocide lasts longer and less chemical is needed to control bacteria."
