The RO-treated water has hardness; please help analyze it. Good answers will earn extra points!

Is the RO membrane clogged, and what is the quality of the raw water? Do you remember what the hardness was? What about conductivity?
Reply #32012-11-15
The membrane should not be clogged; it was just cleaned； Original water conductivity: 326 us/cm, hardness: 1.33 mmol/l ； The water conductivity at the power plant is 10.94 us/cm, and the hardness is 0.04 mmol/l.
