Circulating water biocides are essential chemicals for ensuring the proper operation of circulating water systems. They exhibit high-efficiency bactericidal activity, rapidly inhibiting and eliminating bacteria, fungi, algae, and other microorganisms in the water, thereby preventing the formation of biofouling sludge. These biocides have a broad spectrum of efficacy and demonstrate significant effectiveness against a wide range of harmful microorganisms. Chemically stable, they maintain their activity under varying water quality and environmental conditions. They are safe to use, cause minimal corrosion to equipment, and thus help extend equipment service life. Additionally, they possess a certain biofilm-stripping capability, effectively removing existing microbial biofilms. Their dosing methods are flexible and operation is straightforward, significantly reducing the operating costs of circulating water systems and ensuring stable, efficient system performance.
Product Introduction：
Circulating water disinfectants are chemical agents specifically designed to control the growth of microorganisms (such as bacteria, fungi, and algae) in circulating water systems. Their main components include oxidizing disinfectants (such as chlorine compounds, bromine compounds, and chlorine dioxide) and non-oxidizing disinfectants (such as quaternary ammonium salts and isothiazolinones). By disrupting the cell structure of microorganisms or inhibiting their metabolic processes, they effectively kill and inhibit the reproduction of microorganisms in the water, preventing biofilm formation and the resulting problems such as corrosion, clogging, and decreased heat exchange efficiency.
Product Advantages：
Highly Effective Disinfection
Rapidly kills bacteria, fungi, and algae in water, offering broad-spectrum efficacy against a wide range of microorganisms.
Dual-Mode Mechanism
Oxidizing biocides destroy microbial cell walls through oxidation, while non-oxidizing biocides inhibit microbial metabolism. When used in combination, they enhance overall biocidal efficacy.
Long-Lasting Microbial Control
Maintains antimicrobial efficacy in water over an extended period, reducing the risk of microbial regrowth.
Wide Applicability
Suitable for use across a range of water quality conditions and pH levels, with strong adaptability—particularly effective in high-hardness, high-alkalinity water.
Safe and Environmentally Friendly
Certain products leave no residue or break down into harmless substances, meeting green chemistry standards and minimizing environmental impact.
Easy to Use
Can be directly dosed into circulating water without requiring complex equipment or processes, making it simple to implement.
Cost-Effective and Efficient
Reduces microbiologically induced corrosion, fouling, and heat transfer inefficiencies, thereby lowering system maintenance costs.
Strong Resistance to Microbial Resistance
Non-oxidizing biocides act by disrupting microbial metabolism, making it difficult for microbes to develop resistance—ideal for long-term use.
Circulating water biocides are widely used in the following industries:
Industrial cooling systems
In industries such as power generation, steel manufacturing, and chemical processing, they are used to control microbial growth in cooling water systems, preventing biofilm formation and equipment corrosion.
Central air conditioning systems
Eliminates algae and bacteria in air conditioning cooling water systems, improving cooling efficiency and extending equipment lifespan.
Food and beverage industry
Ensure the hygiene and safety of process water to prevent microbial contamination from affecting product quality.
Pharmaceutical industry
Control microorganisms in pharmaceutical water systems to meet stringent hygiene standards.
Textile and dyeing industry
Prevent microbial growth in dyeing equipment and hot water systems to ensure process stability.
Papermaking industry
