Why is Chemical treatment of Jacket Cooling water necessary on a ship?

Jacket cooling water is used on ship to maintain the temperature of the main engine and Chemical treatment of Jacket Cooling water in necessary for the following reasons:

1. Corrosion prevention: chemical treatment with inhibitors helps to prevent the corrosion of the metal component in the cooling system, which can lead to costly damage and leaks.
2. Sludge formation control: Treatment chemicals prevent the formation of sludge and deposit in the system which can reduce heat transfer efficiency and clog the system.
3. Scale deposit prevention: proper chemical treatment prevents the scale formation that can form on the heating exchanging surfaces and reduces the efficiency and heat transfer.
4. pH control: Chemical treatment helps maintain the pH of the cooling water within a specific range, preventing acidic or alkaline conditions that can contribute to corrosion and scaling.
