Water treatment additives play a critical role in maintaining the health of closed loop water systems. These systems are commonly used in industrial applications such as cooling towers, boilers, and HVAC systems. Closed loop water systems require careful management to prevent corrosion, scaling, and biological growth that can lead to system failures, reduced efficiency, and increased maintenance costs.
In this blog post, we will explore five types of water treatment additives for closed loop systems: corrosion inhibitors, de-scaling agents, de-sludger, anti-freeze glycol, and non-potable biocides.
Corrosion inhibitors are a common type of water treatment additive used to prevent corrosion in closed loop systems. These additives work by forming a protective film on the metal surfaces of the system, preventing corrosion, and extending the life of the system. Common types of corrosion inhibitors include zinc, molybdate, and nitrite.

Scaling occurs when mineral deposits build up on the surface of the system, reducing flow and efficiency. De-scaling agents are water treatment additives used to prevent or remove these deposits. These additives work by breaking down the mineral deposits and preventing them from forming again. Common types of de-scaling agents include phosphoric acid, citric acid, and hydrochloric acid.

Sludge is a build-up of organic matter and other contaminants that can accumulate in the closed loop system, leading to reduced efficiency and equipment failure. De-sludgers are water treatment additives that work by breaking down and removing sludge from the system. These additives help to improve the efficiency of the system and extend the life of the equipment.

In colder climates, closed loop systems can be at risk of freezing, which can cause damage to the system. Anti-freeze glycol is an additive that is added to the water to lower its freezing point, making it less likely to freeze. It is important to use the correct concentration of anti-freeze glycol, as too much can reduce the efficiency of the system.

Non-potable biocides are chemicals used to control the growth of microorganisms, such as bacteria and algae. In closed loop water systems, microorganisms can multiply and form biofilms that can lead to several issues such as corrosion, fouling, and reduced heat transfer efficiency. Non-potable biocides are used to control the growth of these microorganisms and prevent these issues from occurring. It’s important to note that non-potable biocides should be used in accordance with local regulations and industry standards, as they can have potential health and environmental impacts if not used properly.
