We are installing a R O plant to recycle effluent water. We find that the
Total dissolved solids to be alright at 60 PPM but find that the copper in
the water to be about 1 PPM.

Is there any bad effects of presence of copper in rinse waters. Whereever
criticallike bath makeup,gold plating etc we use DI water.

If no how much is tolerable.

An immediate reply on the above will be much appreciated.

Regards

N Radhakrishnan
