For both these you list as the trigger to signal trouble. "Lab analysis indicates unstable product or off-spec material.' It would seem to me that a much earlier warning of trouble in these areas could be obtained by analyzing the contents of the FeCl3 mix tank and the #6 chlorinator to determine the concentration of catalyst present in them. Low catalyst level will produce unstable material. I recommend that cata lyst level in #6 chlorinator be determined regularly to give early warning of liklihood of unstable product being produced. Perhaps the FeCl3 mix tank should be analyzed regularly too. a R. JP 005353? TOWOLDMONOQ45064
