Water quality control for cooling circulating water
Thread Content
In an open-type cooling water circulation system, it was found after operation for some time that the iron content in the water was relatively high； The water discharged during the cleaning of a plate heat exchanger is also turbid and reddish in color. How should this situation be handled?
This situation is usually caused by corrosion within the system, which leads to the corrosion of iron materials and the release of iron ions into the water. The countermeasures are as follows: 1. Check and adjust the pH level of the water as well as other chemical components, keeping them within appropriate ranges to reduce corrosion. 2. Enhance the water treatment measures for the cooling water system, such as adding corrosion inhibitors and scale inhibitors. 3. Regularly clean the interior of the system, including heat exchangers and pipes, to remove deposits and corrosion products. 4. Consider replacing or repairing severely corroded components. 5. Regularly monitor water quality, especially iron levels, to ensure the effectiveness of water treatment measures. Through these measures, water quality issues in open cooling circulating water systems can be effectively controlled and improved, thereby extending the lifespan of the equipment. .
The simplest solution is to increase the frequency and duration of waste discharge
1. Regarding adjusting the pH value of water, what range is appropriate to maintain it at, and how can it be optimized?
1. Adjust the pH value of water; what range is appropriate, and how can it be optimized? 2. Regularly clean the inside of the system – does this involve chemical cleaning?
Will increasing the frequency of wastewater discharge cause the chemicals to become ineffective, since the chemicals are also carried away during the wastewater replacement process?
In air conditioning systems with an open cooling water system, the quality requirements specify that the pH of the circulating water should be between 7.5 and 9.5, while the pH of the make-up water should be between 6.5 and 8.5; this can serve as a reference
The standard name is \"Water Quality for Heating and Air Conditioning Systems\"
With different pipe materials and chemicals, there is still a difference compared to the chemical industry, right?
There are books on industrial water treatment on the forum; you might as well search for them and download them to take a look.
Strengthen waste discharge control to achieve thorough purification.
