In this video, we use the breakpoint curve to show how chloramines are formed, how chloramines and chlorine interact to form dichloramines and trichloramines, and why mixing chloraminated and chlorinated waters is a bad idea. Watching my "Breakpoint Chlorination" video prior to this is recommended, but not necessary.
Thank you so much, i'm currently on the disinfection and chlorination chapter in my operation of wastewater treatment book and you just helped me out tremendously, i've read over the breakpoint and chloramination process section multiple times and it wasn't clicking at all. your video and breakdown made so much more of a difference.
Great energy and information, Writing the entry level exam. Enjoy the podcast as well.
Thank you Dan! Best of luck with your exam!
Whats up Ty its Ebert. Finally watched one of your videos brotha. Very informative I had a lot of experience with chloramination prior to working with you in Oakdale. You hit the nail on the head.
Hey Jason! Nice to hear from you! Thank you for the compliments. I've been by the plant a few times but keep catching you on your days off. Hopefully next time I can see you there and say hi. Hope things are going well.
Thanks for the video.
Ist Video of yours I have watched, VERY WELL EXPLAINED! Thanks for the Education! RockON
Thanks Brian! Much appreciated.
REALLY appreciate your videos, man. :)
2021 thanks dude appreciate the good work
Thank you!
I'm doing surface water supplemented to ground water R.O. system. The EPA requires us to chlorinate to free within our system to reduce the amount of THM from mixing ground with with surface water.
I got worried when he couldn't say nitrification. I think that's what he was trying to say. But I pushed on and am happy I did.
lol.... When you stand there in a room by yourself, staring at a camera with lights on you trying to record these things, its pretty easy to stumble on words... at least when you are first getting started. I restarted the intro to my "pH and alkalinity" video like 12 times. :-)
😂😂😂
Very good video. I love your teaching method.
Q. would it be a problem to dose ammonia into the storage tank, that is currently being used for cl2 burn out? With a residual of 2.0. I would think I can dose by pounds formula and add the right amount of nh3 to bring the GST into a chloramines and then flush the system.
you got me through to my B exam now I just need the advance studies to get my A license in Florida do you still put out studies?
Hey RocketMan. Thanks for the nice words. I do not do any in person teaching, but I do update the site as needed. If you go to the link in the info above, it will take you there. When you get there, please go to the "questions" tab and click on "Will you be coming out with any more podcasts?"
@Andy Z operator
I think you should have completed the formula for chlorine as in the final one with stats
2NCl3(aq) + HOCl(aq) = N2(g) + Cl2(g) + H2O(l)
Thank you.
Water Sufi, I love all the work you have put into all your recordings. You totally helped me for my CA treatment exams. I would listen to your audio on my way to work and any other time I could when I wasn't able to read and study. I just want to thank you.
I went to a hach training last week about chloramination and nitrification and the question was asked which chloramine was the strongest disinfectant mono, di, or tri and the answer was tri is stronger than di and di was stronger than mono which goes against the comment you make around the 8 minute mark. Can you please expound.
Lastly I wanted to ask if I am shooting for a 5:1 Cl2:N ratio by dosing ammonia, does my total chlorine drop if I am over or under shooting so if I am at a 4:1 or 6:1 Cl2:N will my total cl2 be lower than if I was at a perfect 5:1?
Hi Joseph,
Thanks for the kind complements about the podcasts. To answer your question, let me start by first giving you some definitions directly from the AWWA.
Monochloramine: A disinfectant used to inactivate disease-causing organisms in distribution systems ...
Dichloramine: A disinfectant produced to a lesser extent than monochloramine, in low pH and high chlorine to ammonia-nitrogen ratios.
Trichloramine: Also called nitrogen trichloride ... has little disinfection capacity and is the source of tastes and odors.
In addition, Di's and Tris also are much more unstable and have a much greater propensity for causing tastes and odors in the system. Aside from all that, you can even see from my chart in the video what happens to overall residual and disinfectant ability with the formation of dis and tris. Your best disinfection using choramination is with mono, as you continue past a 5-1 ratio, and start forming dis in place of mono, your residual and disinfecting ability starts to drop.
So if you are producing a Monochloramine would you be able to detect both excess free ammonia and free chlorine or is that a pretty good sign of free chlorine territory?
what would you say is a good free ammonia leaving the plant and free chlorine for that perfect cushion ?
We have to have >0.2 mg/l free Chlorine out of the contact chamber, greater than 0.2 mg/l of total in the distribution system. So we don't do break point chlorination. What would be the sufficient ratio of chlorine to ammonia to keep the total chlorine in the 1.5 mg/l range?Ammonia is added to the clearwell after the contact chamber.
What happens when water containing chlorine and reaching the Chlorine boiling point?
The Chlorine will vanish?
Thank you.
I wish u lived in Hartford CT
Would you detect free chlorine making monocloramines and what would that be at say 5.1 ratio?
Starts at 1:50
Hey man, If you skip to 1:50 you'll miss some information about the video that comes before this one... as well as my wonderful shirt story. :-)
Jason it’s time to set the information about 80% of home owners always have GREEN pools this is because CYA & now we have the info, about borates 😀
Question : Anyway to know the chlorine toxicity level toward aqua species, shrimp ?
I find a lot of people watch this video for aquarium operating or pool maintenance information, but my whole experience is with drinking water treatment and distribution, so I can't help you with that. Sorry.
But the said that chloramines do NOt have disinfecting power
Chloramines are disinfectants. No question about it. Not sure where you heard that. Maybe it was an answer on a multiple choice question you saw? Questions like "which of the following is not a disinfectant?" or "which of the following is a disinfectant?" are common. You may also be confusing monochloramines with dichloramines and trichloramines. Watch the video starting at about 5:00 in. I go over the difference.
Hey there, Water Sifu! I was wondering: if the water in my house is full of chloramine, will a carbon filter remove it? Or would it just break the chloramine bonds and leave ammonia to be free roaming in my water? Thanks in advance
I personally would not be too concerned about removing chloramines, but if you are interested in that, in the interest of serving your answer best, I would recommend doing a simple google search for "will carbon filters remove chloramines?". It will return a ton of links and much more in-depth answers on the subject than I could get into in the space I have here. Bottom line though is that it shouldn't be too hard.
@@TheWaterSifu Respectfully, I am already past a "simple google search" that's why I asked you for a more detailed explanation to my question. Yes it is already understood that typical carbon filters remove the chlorine. My question is would the removal of chlorine from chloramine create an excess of free roaming ammonia in the water?
hey I was just curious does your testing information apply to the state of Tennessee? I go to take my water treatment test around January, but the test i will be taking will new test that will have an operator certified to work anywhere in America. I've been told its one of the most difficult test.
Yes….
For years now I have been talking with people in all states across the country that have used this material to pass their certification exams with great success. Ironically, I have found that even people in Canada have found this information very helpful in passing their exams. (I didn’t even know they had certification exams up there when I started) What I have learned is that it is not the certification material itself that is different from state to state, it’s just that every state calls their own levels of certification by different names…. some go A,B,C with A being the highest. Some go A,B,C with C being the highest. Here in CA we go 1-5 with 5 being the highest. In Hawaii they only go 1-4 with 4 being the highest. Some states group distribution and treatment together. Others, like California, have different lines of certification for each.
Having said that, regardless of what they call their certifications, the subject matter is all the same. No matter what you call the test, a pump is still a pump, a well is still a well, treatment techniques are still the same, methods of calculating dosages are all the same, etc.
@@TheWaterSifu I'm studying in Canada and found this very helpful!
do you happen to know Gary Gottowski?
Nope. I do not.
I was hoping to find the chemistry reaction for chloramine removal by adding critic acid. Is it real or are they just seeing a ph reaction?
K mad please don't believe this shit although it might kill microbes i don't think it will do much for chloramine, chlorine and flouride for example. The reaction yoi are seeing is most likely just neutralisation.
Sounds like you wear the same shirt all the time
I dress like a beach bum almost 100% of the time, but I do juggle my favorite shirts. :-)
