I suggest you contact several fuel oil additive suppliers such as Baker-Hughes, Nalco, etc. as these folk have many decades of hands-on experience with distillate fuel storage and stability issues including fuel quality, mechanical and chemical considerations.

Sorry, James, but you are incorrect. There is nothing in distilled water that can create a chlorine demand. If you are finding a "chlorine demand" in distilled water, then there is another issue (read error) in your analysis.

Chlorine demand has no relation to the measurement of free chlorine residual. Sample dilution is OK as long as you compensate for the dilution, for example,with two parts chlorine fee (distilled) water and one part sample, the resultant free chlorine value multiplication factor is 3X...
To be more specific, Federal and State regulations prohibit the direct use of reclaimed industrial effluent (through WWTP operations), even that with Class A or better quality, as disinfected potable water. Generally, the effluent must be percolated back into aquifer zones for in-transit further...
If you are in the United States, I believe you will find specific Federal and State restrictions on the "purification" of industrial effluent, or for that matter, reclaimed water for direct use as potable water. I suggest you first check all applicable Federal and State regulations before...
Further to micalbrch's post, and for your consideration, the EPA Secondary Potable Water Standard for zinc is 5 mg/L. This is a non-enforceable standard.

You should pick up a copy of "Wastewater Engineering, Treatment and Reuse", Metcalf & Eddy, Mcgraw Hill, which is considered the bible of wastewater treatment.
Other guys on this forum can guide you to various courses and other educational media.

Given the sodium content of your furnace fuel, I would suggest adding a magnesium-based compound, in yourcase probably an organo-magnesium compound such as magnesium sulfonate or similar to the fuel being burned to form a high melting, essentially non-corrosive and esaily removed (friable)...
I would be more concerned with the presence of sodium in the furnace fuel, which if in any significant concentration will form low melting and corrosive eutectic tube deposits with vanadium. Vanadium as such (without sodium)should essentially oxidize to vanadium pentoxide which I would expect...

In my twenty-some years of pool water chemistry and treatment, I have yet to see a case in a pool water environment where chlorine as hypochlorus acid (or diatomic oxygen) will oxidize iron compounds to an insoluble state which can then be removed by filtration, any more than Jack Bean's...
Bimr:
Generally this removal procedure does not work because pool water pH is not sufficiently high to drive the oxidation of iron compounds to the insoluble hydroxide state.

You might consider application of an iron stain prevention product for pools/spas that will chelate the iron and maintain it in a water soluble state. There are a number of these products available to the recreational water market, some of which should be stocked at your pool supply store.
