Normally the polyelectrolyte ...

Normally the polyelectrolyte has very little effect as its concentration is very low. But the chlorine, if it's FREE CHLORINE, it will definetely have an effect. How big effect is to be determined. If it's total chlorine then you should measure the FREE AVAILABLE CHLORINE.It should be below 0,05 mg/lit.

Thanks for the insight, very interesting regarding poly not having any effect on the yield. I would imagine that it would at least slow the process down a little. Based on the Residual Chlorine amount you have reported, the chlorine will be a problem.

The only chance that polyelectrolyte might slow or even stop the process is if the polymer contains a significant amount of monomer, and if the monomer is toxic.

Total chlorine is not a problem, only free chlorine.
