What is the Role of azoles in water treatment?
Azoles are employed in water treatment because they are structured, ringed organic molecules that prevent corrosion in cooling water management strategies, for copper and copper alloys. Most people who work in the water treatment or cooling tower industries must have heard about Azoles. Azole compounds are utilised to prevent corrosion of the copper alloys, used in cooling systems because of their effectiveness in transferring heat.
Halogens, such as chlorine, fluorine, or bromine, are used in water treatment systems to treat microbial growth. When azoles and halogens are combined, some problem occurs. The defences that azoles offer eventually disintegrate.
This issue is more severe in systems that use benzotriazole or tolytriazole. Due to this, plant managers raise feed rates, which raise both costs and the overall harm done to a system.
How do corrosion inhibitors work?
Chemicals called corrosion inhibitors are introduced to a corrosion system to slow down overall corrosion, without altering the concentration of corrosive chemicals. Depending on the kind of corrosion they're addressing, they can be cathodic, anodic, film-forming, or oxygen absorbing.
If used in modest quantities of water, they are designed particularly to avoid things like the growth of scale. To avoid and get rid of deposits in feedwater systems, corrosion inhibitors are made to be multipurpose for cooling systems.
Most popular corrosion inhibitors
The most common compounds used in wastewater treatment are benzotriazole (BTA) and tolytriazole (TTA). Since, copper is insoluble in both aqueous and organic solutions, benzotriazole is used specially to protect copper.
Similar to benzotriazole, tolytriazole is another yellow metal corrosion inhibitor utilized in industrial applications, where liquid is continuously flowing against corrosive metals. It gives metals a thin hydrophobic layer to help shield them. Before oxidising biocides became widely used in wastewater treatment, these products are effective.
But that's where the issue is!
Water is treated with oxidising biocides during wastewater treatment to help ward off microorganisms. In the realm of wastewater treatment today, legionella is a prevalent worry. As a result, corrosion inhibition failure is brought on by biocides like chlorine that puncture the hydrophobic coating.
Why test cooling waters for Azole?
Testing for azoles in cooling water systems is becoming essential due to corrosion inhibition failure, becoming a more pressing concern. Oxidizing biocides aren't considered when many systems are being developed. This issue arises as a result of the compatibility with other treatment chemicals, a problem that is frequently disregarded.
The natural reaction is to continually add more TTA when levels decline. The issue gets worse as the feed rate rises. Even when additional inhibitors are used, a system's tolytriazole content will eventually increase as chlorine continues to eat away at it. This will result in increased copper alloy corrosion rates. This is why it's crucial to have a specific water treatment plan in place, to keep track of your azoles.
In addition to saving money on chemicals, it will also help keep your wastewater treatment system from being harmed.
