The choice of disinfectant depends on the specific application, the types of microorganisms to be targeted, and regulatory requirements. It's important to use disinfectants correctly and at appropriate concentrations to ensure effective disinfection while avoiding the formation of harmful byproducts or residual chemicals. Additionally, regular monitoring and maintenance of disinfection systems are essential to ensure consistent water quality and safety. Biocides are used to control algae, bacteria, and other microorganisms that can grow in water systems and cause fouling.Biocides are chemicals used in water treatment to control and inhibit the growth of microorganisms, such as bacteria, algae, fungi, and protozoa, in various water systems. They help prevent fouling, microbial corrosion, and the formation of biofilms. Biocides come in various forms, including oxidizing and non-oxidizing agents.
