Selection of chemicals for circulating water in the chlor-alkali industry
Thread Content
Our circulating water system does not have a side filtration system nor a chemical dosing system. For heat exchangers made of various materials in this system, how should we select the appropriate chemical agents? Chlorine, hydrogen peroxide, ozone, chlorine dioxide, organic bromines, and ready-made chemicals? What are their advantages and disadvantages? Usage environment? Operation range? Cost efficiency? Is there a professional who can do a comparison! Thank you. Our water storage capacity is 2,700 cubic meters, and the flow rate is 4,700 cubic meters. The side filtration system is designed for 300 cubic meters of water volume. How should the chemical dosing system be designed?
The water quality needs to be known in order to determine the appropriate treatment. All of the agents you mentioned are oxidizing disinfectants; bleach is commonly used these days as it is inexpensive and convenient. The methods you suggested are more complicated. The filtration rate is usually 5% of the total flow rate. If you have any questions, you can contact me via WeChat at 18026598787
New pure-physics technologies for treating circulating water: scale removal, rust elimination, sterilization, algae control, as well as energy and emission savings. I’m available to discuss this further if needed.
