The goal of a good water treatment program is to ensure that the water has continuous contact with heat exchange surfaces and is free from biological fouling. Biological growth, scale deposition and corrosion could force machines to work harder because of diminished ability of water to interact with the surfaces. Water treatment experts recommend the use of a dual alternating biocide treatment system be employed to enhance the efficiency of water treatment programs. Oxidizing BiocidesBiocides are chemical compounds that kill algae and bacteria in cooling towers as well as other cooling systems that circulate. All biocide chemical can be classified into two classes: non-oxidizing and oxidizing. Each biocide approaches biological organisms in different ways. Oxidizing biocides use the "shotgun" approach to killing the bacteria as well as biological growth. They destroy the cell structure of the organism in order to destroy the cell and ultimately kill the organism. Oxidizing biocides work due to their speed and speed of their approach and organisms are not able to develop resistance to the chemicals that are used to treat water. There are however a couple of drawbacks to the use of oxidizing biocides. These chemicals can enhance the water's corrosiveness. Some oxidizing chemicals used in water treatment programs may also create undesirable byproducts that are bad for the environment. Water treatment programs require constant monitoring of the water's levels and the conditions. Because they interact with other corrosion inhibitor chemicals, oxidizing biocides may make water treatment programs less efficient and difficult to monitor. Non- Oxidizing Biocides A non-oxidizing biocide impedes biological growth in a different way, by interrupting the metabolism of the organism, and effectively poisoning the cells, causing them to die. The IRO Biocide class targets certain cells and organisms. It uses an "rifle method" to treat. Non-oxidizing biocides may also have a minor impact on other chemicals employed to treat corrosion and scale. Due to the numerous microorganisms found in every refrigerant cooling system, non-oxidizing biocides can make it more difficult for them to work. They can also be intolerant to other chemicals and develop within the water. This is why it is crucial to get a professional in water treatment to inspect the water. What is a Dual Alternating Biocide Program Function? Consistent use of one biocide within water treatment programs could cause resistance flora, or damaging conditions in the water. Dual alternating approaches can be a great way to manage the growth of biological organisms. A dual-alternating biocide strategy makes use of both oxidizing as non-oxidizing biocides. The system is fed on an alternate dose of slugs, based on the ongoing observation of the water's conditions. Dispersants are frequently added to non-oxidizing biocides to increase their efficacy. This enhances the biocide's ability of piercing the surface of metal and break up biofilms.
