All indicators are normal, but iron levels are above the normal range

Water parameters: Alkalinity: 270 mg/L, hardness: 850 mg/L, pH: 8.3, conductivity: 1700, scaling control: 2.3, turbidity: 30–40. The iron ion level remains above the limit; let’s find out what’s causing the issue
Check whether the water-using equipment is corroded.
There must be areas of corrosion that cause an increase in iron ions
I want to say that our water flow parameter shouldn’t cause excessive corrosion of the equipment
Are you an indicator for return water or for feed water? It is necessary to check the water output parameters of the equipment.
These are the water quality parameters; do you mean to take samples at each heat exchanger outlet to test for iron ions?
The turbidity level is too high; check the amount of iron ions in the water. In your case, it seems that the system’s corrosion inhibition effect is insufficient, and corrosion is occurring within the system
Check the dissolved oxygen level – it’s such an important parameter, yet it’s missing. I’m not sure whether you’re in the south or the north, nor what type of water you’re using; the turbidity is a bit high, which is likely due to oxygen corrosion. Take a sample of the water and check its color; this can help determine the chromaticity
