What to do about the severe algae growth in the circulating water system of a fertilizer plant?
Thread Content
Since the onset of summer, the amount of bactericides and algaecides used in the circulating water system of the fertilizer plant has been doubled, yet algae growth remains severe. What should be done?
Is it the leakage of organic matter or nitrogen into the circulating water, which leads to an increase in reducing substances and thus a higher demand for oxidants?
What was said upstairs is correct; if ammonia is leaking, using oxidizing disinfectants will yield poor results, and a large amount of such disinfectants will be required. At this point, you need to check for any issues, make replacements, switch to non-oxidizing bactericides, and then proceed with removal. The problem can then be solved.
It is mainly caused by an excess of nutrients in the water, coupled with high temperatures. The following methods can be adopted: 1. Strengthen side filtration ； 2. Increasing the application of disinfectants can keep residual chlorine at 0.6–0.7 mg/L (within one day)
For detailed information or if you need in-depth discussion, please contact me via private message. In a situation like yours, it is necessary to replenish more nutrients and remove more waste; relying solely on bactericides, especially oxidative ones, is costly and not economical.
Oxidizing and non-oxidizing sterilizers can be used alternately
If amines leak, chlorine-based fungicides are less effective, as chloramines are formed and their fungicidal power is weak. It is recommended to first check for any amine leaks; bromine-based fungicides can be used, and even if bromoamines are formed, they are equivalent to hypobromous acid.
Rather than adding chemicals, it is better to use physical methods to prevent the cleaning of the circulation pool. My recirculating water treatment system works very well. We can communicate.
Check for any leaks; there might be issues in that area, and then consider using a high dose of disinfectant.
What type of circulating water treatment is used in open cooling towers to prevent scaling in heat exchangers?
Use a comprehensive water treatment system that provides corrosion and scale prevention, as well as sterilization, algae control, and waste removal.
