Water Treatment Biocides

At Water Treatment Services (WTS), we provide tailored biocide and water disinfectant solutions to ensure the purity and safety of water across any industrial and municipal applications.

For many industrial water applications, unchecked harmful organisms such as biofilm, legionella, and algae cause a range of problems. These microorganisms can accelerate corrosion, disrupt water flow, and collapse heat transfer, leading to potential unplanned shutdowns.

At WTS, we provide water biocide chemicals designed to help control, prevent, or eliminate various harmful organisms. Our technical team customise water biocide technologies that help mitigate risk, ensure efficiency, and protect your assets.

What are Water Biocides?

Water biocides are chemical substances designed to control, prevent, or eliminate harmful organisms in water systems. These organisms include bacteria and viruses, algae, fungi, moulds, and other microorganisms that can cause corrosion, fouling, or health risks.

1. Visible Slime, Fouling, or Unusual Odours Slime deposits on pipes, tanks, or cooling tower fill, and sulphur-like odours from the water, are surface indicators of an established microbial population requiring immediate attention.
2. Declining Heat Transfer and Rising Energy Consumption Biofilm on heat exchanger and cooling tower surfaces insulates against heat transfer, forcing systems to work harder for the same thermal output. A rising energy demand without a mechanical cause usually points to biological fouling.
3. Legionella Risk and Compliance Exposure Uncontrolled biological growth in cooling systems creates conditions for Legionella pneumophila to establish. In Queensland, cooling tower operators carry specific obligations under the Public Health Act 2005. Documented gaps in a biocide program put both operations and compliance standing at risk.

Our Range of Water Biocides

At WTS, we understand that each water or wastewater treatment scenario presents its own unique challenges. That’s why we maintain a comprehensive range of water biocides designed to address a diverse array of microbial control needs.

Our solutions include:

Oxidising Biocides

Chlorine-based biocides are versatile and widely used disinfectants recognised for their effectiveness in disinfecting water systems in industrial and municipal applications. They act by oxidising and disrupting the cellular structures of microorganisms, rendering them inactive. Our chlorine-based biocides are available in various forms, including liquid, granular, and tablet formulations. This gives our water treatment experts flexibility in how they apply the solution, enabling effective disinfection across a wide range of water treatment scenarios.

Hydrogen Peroxide Biocides

Hydrogen peroxide biocides are another oxidising solution utilised for microbial control in industrial and municipal water treatment applications. They offer rapid and effective disinfection by oxidising and eliminating microorganisms, including bacteria, viruses, and algae. Our hydrogen peroxide biocides are formulated to ensure optimal performance while minimising environmental impact and ensuring safety in water treatment processes.

Bromine-Based Biocides

Bromine-based biocides offer an alternative to chlorine, providing effective disinfection with distinct advantages in certain applications. Bromine exhibits similar disinfection properties to chlorine but with a typically shorter life and fast action in most situations, as well as greater stability and efficacy in higher temperature and pH situations. Our bromine-based biocides are formulated to ensure optimal performance while minimising adverse effects on water quality and equipment.

Chlorine-Dioxide Biocides

Chlorine dioxide carries 2.5 times the oxidising power of chlorine, acts selectively to reduce corrosion risk, and destroys biofilms that shield bacteria from other disinfectants. It produces no trihalomethane byproducts, reacts minimally with ammonia and organic matter, and is gaining broad use across potable water, cooling towers, boiler systems, and Legionella control. WTS generates ClO2 on site.

Non-Oxidising Biocides

Non-oxidising biocides offer gentler alternatives for water treatment applications where sensitive processes or equipment make oxidising biocides undesirable or unsuitable. Applications requiring long-duration biocide effectiveness also lend themselves well to this group of water biocides.

Quaternary Ammonium Compounds (QACs)

QACs and derivatives feature potent antimicrobial properties, making them valuable biocides in water treatment applications. They disrupt the cell membranes of microorganisms. Our QAC-based biocides are formulated to deliver broad-spectrum antimicrobial activity while remaining compatible with various water treatment systems.

Electrophile Biocides

Electrophile biocides neutralise microorganisms through electrophilic reactions that disrupt cellular function through a different mechanism to conventional oxidising and non-oxidising chemistries. This distinct attack pathway reduces the risk of microbial resistance developing over time. particularly effective in cooling towers and demanding industrial systems where persistent biological pressure makes resistance a genuine operational concern.

Bespoke Water Disinfection Solutions

WTS has a range of advanced water treatment biocide and disinfection tools which can be deployed individually or combined to tackle particularly challenging water chemistry scenarios.

Where Do We Apply Water Biocides?

Why Choose Water Biocide Treatment Solutions from WTS?

Expertise & Innovation

We possess decades of field experience across Queensland’s most demanding industrial water systems.

Our field experience shapes how we develop and refine our biocide programs, applying chemistry that’s been tested against real operating conditions. As your water chemistry, regulatory requirements, and operational demands evolve, so does our approach.

Tailored Biocide Programs

Every water system presents its own microbial risks. Corrosion potential, scaling, fouling, pH, temperature, and downstream process requirements all influence which water biocides will perform and how they need to be applied.

Our team assess these variables across your full treatment process, developing a site-specific biocide program that controls microbial threats without compromising equipment integrity or system efficiency.

Ongoing Support

Implementing a treatment program is the starting point. Our team provides continuous monitoring, troubleshooting, and training so your people and your systems stay ahead of microbial risk.
