Circulating water concentration ratio
Thread Content
What is the typical concentration ratio for circulating water? What is an appropriate maximum value for conductivity?
The concentration ratio of the circulating water should be kept at around 3 times, with a maximum of no more than 4 times. The conductivity is generally not higher than 1000 μS/cm
The concentration ratio is determined based on the quality of the make-up water and the operating conditions; it should not be too high nor too low. The conductivity can be determined according to the concentration ratio
Firstly, the level of conductivity is influenced by the concentration factor, which is determined by the requirements of your water replenishment system. If the concentration factor is too high, the cost of water treatment increases accordingly; in addition, costs related to the treatment of wastewater and water replenishment must also be taken into account, so a comprehensive evaluation is necessary.
About 3.4 times. Is the salt content in the water high?
The concentration ratio depends on the quality of the water used for make-up and the level of control over corrosion and scale inhibitors. From the perspective of water savings and economic operation, the concentration ratio should be at least 3; when the effectiveness of the chemicals permits, a ratio of around 4 to 5 is more economical. Beyond that, maintaining water quality stability becomes much more difficult, while the economic benefits do not change significantly. ,

A ratio above 4 does not result in particularly significant water savings, but it increases the operating pressure.
