This explanation of breakpoint chlorination is misleading, and is better understood from the perspective of potable water treatment plant operations. The unit of the x-axis should be the ratio of chlorine to ammonia (Cl2:NH3), as these ratios are what correspond to the peak and valley along the curve. Saying that "x" concentration of chlorine yields "y" concentration of chlorine residual is way oversimplified as it's not taking into account what else is in the water
That’s good input. This comes from aquatics textbooks but I like the idea of visualizing it better. We are always looking for better ways to explain concepts and make them understandable. Good feedback, thank you
If it’s an enzyme, what pH and temperature range is it effective/ most effective at? Also a little confused about the whole superchlorination process. What chemically happens to trichloramine when you add a lot of chlorine? What happens when it’s ‘burnt’ out?
Great questions. For enzymes, warmer, more agitated and oxygenated water is best. Cold water slows their reaction time way down. They become effective above about 65°F. Not sure how much the pH impacts enzyme activity, but we don’t know of a difference in performance within typical pool chemistry range (7.2 - 8.2). As for superchlorination, when trichloramine is created, it will off-gas and leave the water. Other disinfection byproducts will do the same, like trihalomethanes.
Hmm. That’s an interesting question... we actually don’t know if chlorine evaporates or breaks down in boiling temperatures. We can look into that though.
If all my LSI parameters are optimal, and my pool is just bottoming out on chlorine, zero combined and free chlorine, how much should I add to get it to its normal range?
LSI and chlorination aren’t directly related. Test for metals and phosphates. Most chlorine demand is due to some sort of oxidant, and/or rapidly reproducing algae.
Interesting question. Not that we know of, but be aware that this breakpoint curve is a representation of what is happening constantly. It’s happening faster where chlorine is added and slower in parts of the water that have to wait for circulation to catch up.
Enzymes help with non-living organics, which helps optimize chlorine against everything else, but enzymes do not directly reduce nitrogen compounds or anything living. The idea behind them, as it pertains to breakpoint, is to have more chlorine available for this process from the beginning. The real chlorine savings is against organics.
CV-600. It removes bather waste from water, but not nitrogen compounds like ammonia. CV-600 frees up HOCl to get through the breakpoint curve more efficiently.
Hello breakpoint I'm just learning so stay with me here so basically when I get my Free chlorine, # and say it reads 4.2ppm and then I get the Total chlorine # 4.1ppm so basically i wouldn't need to shock or reach a breakpoint chlorination because my free is higher than my total which tells me their is no CHLORAMINES is this correct little confused ??? , chris M , thanks 👍
Well, technically it's impossible to have those readings. Total chlorine (TAC) MUST be ≥ free chlorine (FAC). So if you have 4.1 total and 4.2 free, your test kit is incorrect. But yes if they were equal you would not have a nitrogen load requiring a shock to reach breakpoint chlorination.
I've met an Orenda guy. They're smart and friendly.
You didn't explain how to get to the break point sooner.
beautiful explanation! Thanks
Thank you
Thank you, very well explained.
Thank you, very good compliment!
Thank you really loved the you explained❤

👍 well explained
Thank you 🙂
Amazing vdo...very helpful
Thank you for watching!
Thank you!
Thank you so much sir
You are most welcome
How much do you recommend adding when refilling the pool?
Purge dose of CV-600/700 is 32 fl.oz. per 10,000 gallons.

What's the difference of tap water reaching the temperature of Chlorine boiling point?
Chlorine will evaporate?

Question : what happen if you put chlorine in the Ponds full of shrimp combine with waste Feed and plankton ? will the breakpoint longer ?
No idea. We do swimming pool chemistry, and are not qualified for giving advice on water containing marine life. Sorry.
is it possible two have two breakpoint in our curve? is yes which one id preferable in our design
Interesting question. Not that we know of, but be aware that this breakpoint curve is a representation of what is happening constantly. It’s happening faster where chlorine is added and slower in parts of the water that have to wait for circulation to catch up.
What is the new formula for adding chlorine if adding cv600? How much less chlorine?
Enzymes help with non-living organics, which helps optimize chlorine against everything else, but enzymes do not directly reduce nitrogen compounds or anything living. The idea behind them, as it pertains to breakpoint, is to have more chlorine available for this process from the beginning. The real chlorine savings is against organics.
What’s the name of the enzyme you add to aid in reduction of chlorine added to achieve breakpoint?
CV-600. It removes bather waste from water, but not nitrogen compounds like ammonia. CV-600 frees up HOCl to get through the breakpoint curve more efficiently.
