A biocide is a chemical compound or microorganism intended to kill any harmful, harmless or control potentially harmful organism. Biocides can be described as "a range of poisonous substances employed to eliminate organisms that pose a threat to human or animal health or may cause harm to natural or manufactured products. This includes preservatives and insecticides, disinfectants, pesticides, and pesticides."

It is important to distinguish between biocidal active ingredients and biocidal products when talking about biocides. Even though biocidal active ingredients are mostly chemical compounds, microorganisms can also be present (e.g. bacteria). Some active biocidal chemicals are present in biocidal products. Other coformulants that are not active can also be employed to guarantee the effectiveness of the product and to achieve desired pH, viscosity, color and the odor.

What is the use of biocides? And what are the benefits?

Control of microbiological activity is a key aspect in various manufacturing, commercial and industrial processes. Chemical biocides are critical for maintaining water conditions at all times in order to ensure that systems are safe maintained, reliable, and work with maximum efficiency.

This is achievable through the application of carefully selected biocide chemical in conjunction with dispersants. They can be used for numerous environmental hygiene activities and process and industrial water treatment, which require effective microbiological activity monitoring.

Biocides can be used for a variety of purposes that include:

1. Bacterial deposits

2. Under scum deposits, bio-corrosion develops

3.Excessive use of cooling fans causes loss of energy

4.Circulation pumps and inefficient heat exchangers

What are the benefits?

Biocides were developed to be harmful to microorganisms such as mold and bacteria. The proper dosage of biocides may be effective and produces a fast result in areas where metalworking fluid is well circulated. Biocides can be used to fight bacterial infections. They are also readily available and easily accessible.

The element chlorine (sodium Hypochlorite).

Chlorine is one of the most commonly used biocides, owing to its low cost and easy availability. While it's the most cost-effective option but its volatile and oxidative nature could damage the metals used in piping systems. When not fed at the appropriate doses, it has been shown to cause corrosion to water in the domestic cooling towers and piping. Chlorine can also produce NTM (trichloronitromethane), a carcinogenic byproduct.

Chlorine Dioxide

Chlorine dioxide, a chloride-based chemical, is employed in domestic and industrial water treatment. It is a well-known choice since it can be utilized in all kinds of makeup water. It is able to penetrate both sessile and planktonic levels of biofilm. Although it is less aggressive than chlorine, its stability in hot water isn't ideal. A generator might be needed to make the chemical on-site.

Stabilized Bromine

Stabilized bromine is used to disinfect cooling towers and is a great option for spas and other places with warm water. Bromine is more expensive than chlorine, but it's more stable in warmer temperatures. Bromine has a less sour scent and is less irritating for the skin. It works in a wider pH range and dissolves slowly which allows you to preserve the water's quality over an extended time.
