Biocides And Disinfectants Application Benefits, Best Practices And Benefits



Bacteria are everywhere. Under ideal conditions, these single cell organisms can multiply as often as every 30 minutes. Within a 12-hour time frame one cell could grow to over 33M. Due to the rapid growth tendency, it is vital to choose the correct technology for disinfection.


Irobiocide is heavily dependent on both oxidizing as well as not-oxidizing biocides in order to eliminate biofilm from cooling towers. Microbicides are also widely accepted in commercial, healthcare food/beverage, and wastewater. In this article, we will discuss some of the most well-known microbicides that are oxidizing and their benefits as well as their most common uses.


How to Choose the Best Biocide for Your Project


There are a variety of options to stop and control microbial growth. You can decide which method is the best one for your needs by comparing the advantages and drawbacks of each.


Common Biocides and Disinfectants


Chlorine (sodium hypochlorite)


Since it is cheap and readily accessible, chlorine is one of the most sought-after IRO Biocide. While it is typically the cheapest option due to its high volatile and oxidative state, it can be aggressive to the metals used in your pipes. It's been proven to cause corrosion specifically in domestic cooling towers and water piping systems if it is not fed in appropriate doses. Chlorine can also form NTM (trichloronitromethane).


Stabilized Bromine


To clean cooling towers, stabilized bromine is used. It's also an ideal choice for spas and other areas that use warmer water. Bromine is more expensive than chlorine, but more stable at higher temperatures. Bromine is less odorous and is not as irritating to skin. It is effective in a wide spectrum of pH levels and disintegrates slowly, allowing you to maintain water quality for a longer time period.


Chlorine Dioxide


A chlorine-based chemistry, chlorine dioxide is used for domestic and process water treatment. It is a popular choice since it is able to be utilized in all types of makeup water. It can be able to penetrate both planktonic and sessile levels of the biofilm. Although it is less aggressive than chlorine however its ability to withstand hot water is less than desirable. Another drawback could be that a generator may be required to make the chemical on-site.


MANUFACTURING application: Irobiocide recently used chlorine dioxide in their Whey production facility to disinfect their COW (Condensate of Whey) Water. The presence of COW water in reverse osmosis systems could cause microbiological fouling like ammonia condenser bulk, boiler feedwater and membranes. The residual ClO2disinfectant took out organics responsible for the fouling, thus the system could perform more effectively.




Monochloramines have the highest stability of the three chlorine-based disinfectants. Not only does the stability improve the efficacy of the product and allow it to stay in solution for extended durations however, it has also been confirmed to be the most non-corrosive chlorine-based chemical. Its primary function involves disinfecting drinking water as well as penetrating biofilm within domestic hot water systems used in health care.


Healthcare, Commercial & Industrial applications Irobiocide strongly suggests monochloramine for hot water systems with high levels of bacteria. Because most municipalities utilize chlorine as their primary disinfectant, healthcare facilities have to add monochloramines to fight waterborne pathogens that are resistant to low residuals of chlorine free. In addition hot water systems within houses are heated to a point where bacteria thrives (70-110F). Additional disinfection may be added to prevent bacteria amplification in time and to remove biofilm.


Peracetic Acid


Peracetic acid is a cost-effective IRO Biocide that kills microbes and leaves no the residue on your GMP surfaces. It is a non-toxic chemical with a few by-products. However, its main drawback is that it is highly corrosive. It is commonly used in the food and drink industry, as well as in hospitals for sterilization of equipment and instruments.


FOOD AND BEVERAGE: Peracetic Acid is an oxidizer which can be used to disinfect equipment and food products within the industry of food processing. Because it doesn't create harmful byproducts, it's ideal to use in air cleaners.


Hydrogen Peroxide


Hydrogen peroxide is a solution to inhibit the growth of microbes in water sources.


The application of hydrogen peroxide to wastewater: One Irobiocide wastewater client has been successful in feeding hydrogen peroxide into anaerobic soils prior to their screw press. Hydrogen peroxide can be added to the water to lyse bacteria. This allows for liquid release from the solids, which permits more efficient dewatering. This results in lower feed rates for chemical substances and higher cake's dryness following the screw press.
