A good water treatment program will ensure that water is always in contact with heat exchange surfaces. Equipment is caused to work harder through biological growth, scale deposition and corrosion. Water treatment professionals recommend the use of a dual alternating biocide system be used to improve the efficacy of water treatment strategies. You may get additionalinformation about chemical substance by browsing biocide manufacturers site. Oxidizing BiocidesBiocides are substances used to eliminate algae and bacteria present in cooling towers as well as other cooling systems with recirculating. All biocide chemical can be divided into two classes: oxidizing and non-oxidizing. Each biocide type approaches biological organisms in an entirely different way. Oxidizing biocides take an "shot gun" approach to destroying bacteria and biological growth. These biocides destroy the cell structure of the organism, causing it to break down the cell and , ultimately, kill the organism. Oxidizing biocides work due to their speed and nature of their approach and organisms cannot build resistance to the chemical that are used to treat water. There are however a few disadvantages associated with the use of biocides that oxidize. These chemicals can enhance the corrosion of water. Other oxidizing chemicals that are employed in water treatment may also create undesirable byproducts that can be harmful to our environment. All water treatment programs require continuous monitoring of water conditions and chemical levels. Because they interact with other corrosion inhibiting chemicals, oxidizing biocides can cause water treatment programs to be less efficient and difficult to track. Non- Oxidizing Biocides Non-oxidizing biocide is a non-oxidizing agent that targets biological growth in an entirely new way. It interrupts the metabolism of the organism and poisons the cells to prevent them from growing. This kind of biocide chemical is targeted at specific organisms and cellular processes, taking an "rifle" approach to treatment. An added advantage of biocides with no oxidizing properties is that they will be very low or have no effect on other chemicals used to treat corrosion and scale. Due to the numerous microorganisms that in any refrigerant cooling system that non-oxidizing biocides could cause more difficulty for them to be effective. They may also become resistant to other chemicals and grow in the water. This is why it is crucial to employ a water treatment technician to inspect the water. How Does A Dual Alternating Biocide Program Work? The continuous use of a single biocide in a water treatment system can result in resistance flora and harmful conditions in the water, which makes an approach that is dual alternating optimal to manage the biological growth. A dual alternating biocide program makes use of both oxidizing as non-oxidizing biocides. It is fed on an alternate dose of slugs, based on the ongoing monitoring of water conditions. Often , in order to boost the efficacy of non-oxidizing biocides, a dispersant is added to help loosen and penetrate biofilms connected to metal surfaces in a way that permits the biocide to perform better.
