Circulating cooling water bactericides and algaecides are commonly used water treatment agents for sterilizing, raoving algae, and disinfecting water in circulating cooling systas. Below are several common types:
Cationic surfactant bactericides: Such as quaternary ammonium salts and copper ions, which kill bacteria, viruses, and microorganisms. These agents are convenient to use and highly effective, but they also possess certain toxicity and corrosiveness.
Oxidizing disinfectants: Examples include hydrogen peroxide and ozone, which oxidize and decompose organic matter and microorganisms in water to achieve sterilization and algicide effects. This method thoroughly eliminates harmful substances without leaving toxic residues, but requires careful concentration control to prevent systa corrosion.
Microbial enzyme biocides: Examples include glucanase and protease. These agents degrade organic matter and microbial cell mabranes to achieve sterilization and algicide effects. They are convenient to use and provide stable efficacy, but are unsuitable for high-taperature environments or those with low pH levels.
It is important to note that when selecting a bactericide and algicide for circulating cooling water, choices should be made based on comprehensive consideration of specific water quality, environmental conditions, and usage requiraents. During application, dosage and concentration must be strictly controlled to prevent adverse effects on the systa. Additionally, relevant safety operating procedures must be followed to protect both operators and the environment from unnecessary harm.
