What does biocide do to water?
Routine biocide application is a standard treatment of cooling tower water, to ensure that bacteria are under control and the potential for Legionella is minimized. Oxidizing biocides kill microorganisms by destroying their cell walls. Examples include chlorine, bromine, chlorine dioxide, and peracetic acid.
What is biocide injection?
Biocide Injection to Eliminate the Risk of Bacterial Growth and Corrosion Failure in Non Internal Coated Pressure Safety Valve from an Eocene Sub Centre at Partitioned Zone (Kingdom of Saudi Arabia and Kuwait).
What is the purpose of biocide?
Biocides are widely used in the food industry as disinfectants and food preservatives. They treat production plants, processing areas and food containers to control the microbial growth in food and drinks.
Why are biocides added to cooling tower water?
Why are biocides used in cooling water? Biocides are used to control bacteria in cooling water systems. Failure to implement a good cooling water biocide program may lead to bacteria and under deposit corrosion.
Are biocides harmful to humans?
Biocides are used to control harmful and unwanted organisms and microorganisms. However, not only do they kill pathogens, they also kill non-pathogens, meaning they may also be dangerous for humans. Biocides pose a particular risk to pregnant women, unborn life, small children, or people with serious chronic illness.
What does biocide mean?
A biocide is defined as a chemical substance or microorganism intended to destroy, deter, render harmless or exert a controlling effect on any harmful organism by chemical or biological means.
How do biocides work?
According to the Biocides Directive (98/8/EC), biocidal products are intended to destroy, render harmless, prevent the action of, or otherwise exert a controlling effect on any harmful organism by chemical or biological means.
What are biocides used for in pipelines?
Biocides are used to eradicate microorganisms in pipelines. At least two biocides may be used alternately for better results and to reduce the bacteria developing immunity to the agents. Biocides can be injected in a batch process depending on the requirements.
How does a biocide work?
Biocides are chemical substances or microorganisms which can deter, render harmless, and kill living organisms. They are used to control and kill harmful and unwanted organisms such as mould, bacteria, algae, insects, and rodents.
What contains biocide?
Many biocides are synthetic, but there are naturally occurring biocides classified as natural biocides, derived from, e.g., bacteria and plants. A biocide can be: A pesticide: this includes fungicides, herbicides, insecticides, algicides, molluscicides, miticides, piscicides, rodenticides, and slimicides.
How do oxidizing biocides work?
Oxidizing biocides are chemicals that have the ability to kill microorganisms through the electrochemical process of oxidation. An oxidizing agent such as chlorine pulls electrons in, while the bacteria it is attacking loses electrons. There are many choices and mechanisms to control bacteria in cooling water systems.
What is the best pH level to maintain in a water tower?
between 6.5 and 7.5
If you have doubts about the proper pH levels for your tower water, ask your water treatment company for recommendations. A pH between 6.5 and 7.5 is generally considered the ideal range for reducing scale formation, though some non-acid treatments for scale prevention can increase the cooling tower pH range up to 8.5.
