I would suspect that there might be some contamination in your condensate being returned from your process. Do you know if there might be steam heating coils that are leaking that could cause contamination ?
Are you also blowing down the bottom blowdown valves regularly? Are you sure that the concentration of chemical being pumped into the boiler is not excessive?
Also there might be a chemical process occuring that is dissolving the scale that is present on the tubes and shell that is adding to the TDS count.
That is all the possibilities that I can think of so good luck with your resolution.
