Which indicators are used to determine whether the circulating water is operating properly?

Total phosphorus, pH, conductivity, residual chlorine, and so on can all indicate whether everything is normal.

The content of solid impurities also needs to be taken into account, as well as the level of ions that tend to cause scaling. It seems that for circulating water, factors like pH value don’t need to be considered, since as long as no acidic substances get into the circulating water, there’s no need to worry about them

The simplest method is to measure conductivity, which is usually sufficient

Measure the scale-forming and non-scale-forming ions in the make-up water and circulating water separately; a comparison will show the difference. Generally, it is chloride ions and calcium ions.

There’s also the turbidity indicator; our plant is an oil refinery, and there have been several instances in our plant where the turbidity levels were not up to standard. I’m also just starting to learn about this. As far as I know, oil emulsification in the circulating water usually occurs after chemicals are added or due to a leak in one of the device’s water coolers. Once the problem is identified, our factory generally uses large amounts of water for displacement and carries out wastewater treatment. To avoid widespread contamination, the design can take into account factors that will facilitate process technicians in identifying problems during future production.

Various ion contents, conductivity, and so on

For circulating water, the main focus is on controlling water quality parameters such as pH, conductivity, turbidity, concentration, total phosphorus, total iron, calcium hardness, total alkalinity, chlorides, ammonia nitrogen, and so on

The circulating water system is primarily designed to control issues such as scaling, corrosion, and the growth of bacteria and algae, and this is generally achieved by adding scale and corrosion inhibitors as well as biocides. Therefore, there are two main categories of control indicators: one is the indicators that reflect the concentration of the agent, such as total phosphorus (for organic phosphorus formulations) and positive phosphorus, etc. The second are indicators of scaling, corrosion, and algal growth, such as turbidity, hardness, conductivity, ammonia nitrogen, etc ； The ratio of scale-inhibiting ions to scale-forming ions in make-up water and circulating water is the most straightforward indicator of whether the reaction system will form scale ； Corrosion is generally monitored by tracking changes in the levels of dissolved ions in circulating water ； Just check to see if fungi and algae are growing.
