Biocide is a chemical treatment that is designed to stop the growth of microbial. Uncontrolled growth of microbial species could cause a myriad of health risks and biofilms, chemical breakdown, heat transfer losses, restriction in flow, and under deposit corrosion.

It is essential that the correct biocidal treatment method is employed and that regular checks are carried out to ensure that there isn't any microbial populations in any of the systems such as drinking water, downwater services processes water, closed circuits and recreational waters.

The control of microbial growth is usually achieved by ensuring the systems are clean at start up and regularly as required, preventing the contamination of systems and delivering using an IRO Biocide or in a continuous manner or via a programme of shock doses.

Types of biocide

There are two types of biocides: oxidising and non-oxidising. Bromine, chlorine dioxide, and hydrogen peroxide are examples of oxidising biocides. Bronopol as well as THPS are examples of biocides that are not oxidising.

There are numerous factors to consider when selecting the IRO Biocide that you choose to use, regardless of whether it is a biocidal flush, maintenance dose, or shock dose biocide. They include contact time temperatures, pH, temperature and compatability. Additionally, the effectiveness against microbes in the system. Technical support can help you choose the right biocide.

Biocide that oxidizes

Oxidising biocides can generally be utilized in lower amounts than non-oxidising ones and their use tends to be more cost effective.

Our most popular chemical are Ultralox 40'" a exclusive active chlorine solution that rapidly eliminates waterborne bacteria as well as breaking down biofilms that house the pathogens that are found in water systems . Ultralox 40'" is highly effective against planktonic and sessile microorganisms. It can be used for water hygiene purposes and pipework treatment applications to quickly remove Legionella. Pseudomonas, as well as other microbes.

Chlorine dioxide

The powerful broad-spectrum oxidising biocide chlorine dioxide is a versatile variety of applications. It is used for disinfection and sanitisation and water treatment. Chlorine dioxide is 2.5x more efficient than chlorine in oxidizing and has a shorter contact time. Chlorine dioxide is effective under alkaline conditions (pH <10) whereas biocide such as sodium hypochlorite lose activity quickly as the pH rises and are not suitable for use at pH >8. The main advantage of chloride dioxide is its capability to eliminate biofilms that is different from other biocides.

Chlorine dioxide is not a common chemical that does not react with other chemicals for water treatment or with nitrogen compounds including ammonia as well as organic materials such as organic acids. Many applications for chlorine dioxide are approved including potablewater treatment, hospital water systems, as well as food processing sanitation.
