Water Quality For 40 Bar Compressor Air Cooling Loop

Hi everybody,

We are using brackish raw water for our factory utility cooling media. 

chemical characteristic of water is:

• pH 7.5 -8.5
• TDS  150
• CALCIUM  15
• SODIUM    10
• MAGNESIUM 5
• CHLORIN 0.5-1 PPM

Since the last two year we are using this water, now we see some rust and debris in the pipeline.

Is this water okay for pipeline or not?

Thank you and regards.
