Cooling Water
Water recirculating in cooling water systems can become contaminated with bacteria, algae, fungi and protozoa that lead to the formation of biofilms – often referred to as slime. Without treatment, cooling systems are vulnerable to the following issues:
|
|
Biofilm formation: Leading to blockages, increased corrosion, reduced heat transfer and increased downtime. |
| Microbially influenced corrosion (MIC): Causing corrosion and pH changes in the system. | |
| Legionella: Representing a severe health hazard if released into the environment. |
Our range of water treatment biocides can help to control biofouling and maintain system integrity in industries that use cooling water in their processes. Such industries include power plants, oil & gas, mining, manufacturing and pulp & paper, as well as many others.
