The water quality test results of the cooling circulating water showed that the levels of chloride ions, iron ions, and calcium ions were above the allowed limits. How should this be addressed?

The flocculant used for making up water in the circulating water system is polyaluminum chloride, with water sourced from the Yangtze River. Iron ions are likely to be present in large quantities due to the carbon steel material used in the pipes, while calcium ions are probably brought in from the water source. .
The water intake should not exceed the limits, right? Is it the system that exceeds the limits? Is the cycle concentration ratio too high? :)

The concentration ratio is too high; it’s necessary to increase the drainage volume
