Circulating water system
Thread Content
I’m a newcomer to the workplace, and I’d like to ask everyone: In a circulating water system, some of the water passes through bypass filtration equipment before going directly into the tank. I’m wondering what the reason for this is Since I studied chemical engineering machinery in school and don’t know much about the manufacturing processes, I would appreciate it if someone with expertise could give me some guidance.
A portion of the water is constantly circulated and filtered to maintain the cleanliness of the entire circulating water system; otherwise, more and more impurities will accumulate~
Generally, there should be no such requirement; different treatment measures need to be adopted according to the specific circumstances of circulating water use. If any suspended particles enter the system, filtration is required ； In cases where water quality is relatively hard and evaporation is high, in addition to replenishing water, chemicals must also be added to prevent scaling in the equipment and similar issues.
Thank you. I also have a question: why can the filtered water be poured directly into the pool, without needing to go through a cooling tower to lower its temperature?
Thank you. It seems that some of our factories do have side filtration equipment, while others don’t.
Very little water passes through the side filtration system; it’s roughly 1/100 of the flow rate, so it has no impact on the temperature of the cooling tower
Water that passes through the side filtration system does not go through the heat exchanger, so its temperature does not change significantly; there is no need to use a cooling tower to lower its temperature
A normal circulating water system is equipped with a bypass filter, which is used primarily to remove suspended particles and impurities from the water tank, thereby ensuring that the cooling effect of the coolers in the system is optimal. Nevertheless, corrosion inhibitors, scale inhibitors, and bactericides are still necessary.
