Circulating water problem
Thread Content
Please ask all seniors: 1. What is the water retention capacity of circulating water? Does it refer to the total water volume of the circulating pool, excluding the water volume of the circulating water pipeline in the device? 2. What is residual chlorine in circulating water? How is it different from chloride ion content and chloride salt?
1. The amount of circulating water retained should be the lowest water level of the pool to ensure normal circulation. 2. The residual chlorine in circulating water is the content of chloride ions in circulating water. Excessive chlorine ion content can easily cause metal corrosion. 3. The residual chlorine in circulating water is the residual flow left when treating water or the content of chloride ions in the groundwater itself: handshake:handshake
Thank you in advance for your answer. :handshake According to what you said, "the residual chlorine in the circulating water is the chloride ion content in the circulating water." Then why is the chlorine ion in the river water we produced is 20mg/l, and after supplementing the industrial water treated with polyaluminum and adding bactericide, the chloride ion in the circulating water should be higher than the chloride ion in the river water. Why is the residual chlorine in the river water only 0.5mg/l?
Refers to the total water capacity of cooling towers, pools, heat exchangers, pipes, equipment, etc. Including the water volume of the circulating water pipeline in the device.
Can anyone help me answer the second question?
Residual chlorine refers to the effective chlorine content in water that is effectively sterilized by chlorine-based fungicides.
Residual chlorine means that after chlorine is put into the water, in addition to consuming part of the chlorine through the interaction with bacteria, microorganisms, organic matter, inorganic matter, etc. in the water, there is still a part of the chlorine left. This part of the chlorine is called residual chlorine. Residual chlorine can be divided into combined residual chlorine and free residual chlorine. The total residual chlorine is the sum of combined residual chlorine and free residual chlorine. I looked up the specifications, but there really is no explanation of the terminology! Maybe it’s a basic concept that must be mastered! To put it bluntly, there is only oxidizing residual chlorine, which mainly exists in the form of CL2, HCLO, etc.
Residual chlorine is an indicator that needs to be controlled when sterilizing and algae-killing liquid chlorine or stable chlorine dioxide in circulating water treatment experiments. The residual chlorine can be used to determine whether the circulating water is effective in sterilizing and algae killing. Generally, the residual chlorine is controlled to be 0.5-1.0ppm. Residual chlorine can also be called available chlorine, which is the oxidizing part, excluding chloride ions. Chloride ions are chloride ions. The two are different concepts
I don’t understand why. The discussion above was clear and clear, and I learned a lot of knowledge. However, there seem to be two answers to the first question raised by the original poster. I think the answer on the second floor is wrong. I think the answer on the fourth floor is correct. The most heard thing about the ownership is about cars. The number of cars is increasing every year, which means that the number of automobiles in the market is constantly increasing. The total is increasing. I don’t know if it is correct?
There are two types of chlorine content, one is total chlorine and the other is free chlorine. I don't know which one you want to control.
