The biggest problems with circulating cooling water are scale and algae. 1. Use a high-concentration softener during cleaning: circulate sodium tripolyphosphate for 3-4 hours, while also using an algaecide to eliminate algae. The above represents the first thorough cleaning before any maintenance or cleaning is carried out. Following those steps will help to **extend the interval between major cleanings while maintaining the system’s effective cooling capabilities. 2. Add sodium tripolyphosphate (or sodium hexametaphosphate) at a rate of 0.2–0.5 kilograms per cubic meter while introducing water, and regularly drain the system and change the water once a week. 3. Prepare the algaecide: 5% citric acid + 0.5% copper sulfate + water to make up to 100%. 4. Adding 10–20 grams per cubic meter of algaecide solution daily can effectively eliminate algae; repeat this process every week when draining the water. Following the above procedures carefully can help maintain the cooling system’s optimal cooling performance, improve the efficiency of the equipment, and extend its service life. Note: Citric acid is a chelating agent; the chelate formed when it reacts with copper sulfate can effectively suppress the growth of algae, and trace amounts of copper ions do not cause pollution to the environment.
