Technical discussion: Water quality treatment for circulating water

This post was last edited by hesonchang214 on 2010-6-3 09:50. The circulating water in chemical plants is essential for production; the conventional method to maintain stable water quality in such systems involves adding corrosion and scale inhibitors. With technological advancements, the treatment of circulating water is moving towards more energy-efficient and environmentally friendly approaches. I would like to discuss with everyone the applications of water treatment technologies: 1. Magnetic treatment of circulating water; 2. Ionized high-voltage electrostatic treatment for circulating water; 3. Low-voltage electronic treatment for circulating water. Are there any practical applications in these areas? How effective is it?
Same feeling as those upstairs! It is not yet accepted by most manufacturers!
The cost is high, and the results are not very satisfactory
Physical descaling must also have its place; I’m currently working on an electronic descaling device, and there are many practical applications for it, with fairly good results. But as mentioned on the 3rd floor, some manufacturers still cannot accept it.
Some manufacturers claim to be able to provide circulating water systems that can perform pulse descaling, algae removal, and sterilization, but it’s not clear whether this is true or not.
It seems to have little effect, and it’s rarely used in practice. In some places, similar equipment was installed, but it had to be replaced with chemical dosing later on
These methods that utilize electric fields, magnetic fields, or ultrasound can only be used as auxiliary measures. Such measures, whether involving electromagnetic fields or ultrasonic waves, have a limited range of action; their effect is confined to the area where their energy fields exist, and this is not sufficient for larger cooling water systems ； Such methods mainly affect the crystallization process of scale-forming ions, thereby preventing scale formation; they have a slight impact on microorganisms as well, but they contribute little to meeting the corrosion inhibition requirements of circulating water ； Although such methods are theoretically effective in preventing scale formation, they often fail in practical applications due to interference from other factors such as installation conditions and impurities in the water. (Often, it’s either 100% effective or completely useless.) For these reasons, the main methods for maintaining water quality are generally chemical methods (which provide stable results and are cost-effective). Methods such as electromagnetic fields or ultrasonic waves can be installed in certain \"dead corners\" of the system or in areas with harsh operating conditions, to serve as supplementary measures to enhance performance
New technologies still have bottlenecks that need to be addressed; current chemical treatment technologies are more mature.
It is costly and not suitable for use in large chemical enterprises.
So what are the disadvantages of using high-voltage electrostatic water treatment in circulating water systems?
