water chlorination system

[Sackett2]

When I was in the Air Force at a ICBM Site in North Dakota, our sites processed the well water and chlorinated it into the 7000 gallon tank for site use.
Chlorine Injection Systems
Ours were like this, a 10 gallon tank we would add bleach and water to a ratio for each site. some took 1/2 gallon, others took 2 gallons. the chlorine also removed iron from the water, a small pump that was adjusted in speed and volume to keep the chlorine level around 2ppm (i think)

While you guys are on this topic, what about sulfur? Not so much any taste, but the smell is not appetizing! ~Scotty

pinch your nose???

 

[KennyV]

what about sulfur?

Scotty is this mainly on the hot water side...?
If so you can simply change out the magnesium anode in the hot water tank.. switch it to an aluminum anode.. smell will be gone. KennyV

Our well water can get pretty funky,. We got some concentrated chlorine pellets, and dump them in when necessary. Usually fixes us up for a few months. Not really a big deal. And theres no complicated system to break down.

KennyV- Nah, just pumped from the well. I wish they hadn't drilled it so deep! I have no HWT, just use point of use electric wall mount. ~S

Take some advice from someone that worked in comercial Chlornators for 30 years, was a trained Service Tech. Don't mess with Chlorline unless you know what you are doing. As for UV can get very expensive Bulbs don't last that long. In know more than one Sewer Plant that has droped UV and went back to Chlorine because of the cost of operation. The system you are talking about installed proplery would cost in the over a $1000 closer to $2000.

Wondering if anyone is using a chlorination system for their well water. I would like to install a system to help disenfect bad water and help with iron. I am trying to think of a way to homebrew a system using a venturi injector to inject a chlorine solution into the water line, then into a holding tank. I have a 3/4" Mazzei venturi I can use, but my main water line is 1". If you have any experience or opinions, please share them.

Do you have bad water? You should typically not have to treat water from a good well. I was a small water systems operator for a few years. I never had a bad sample, but any bad samples from surrounding areas were eventually traced back to poor sampling technique (i.e. taking a sample from a drinking fountain or a swivel type faucet).

On a small scale with sporadic water use, the metered chlorine injection pumps using hypochlorite as the chlorine source are the easiest. Chlortabs are good only if you have a steady flow.

You only need a few PPM of chlorine to get the desired affect. There's nothing I dislike in my water more than the taste of chlorine. Another technology out there that is pretty neat is Chlorine Dioxide. I believe that it's now approved as a treatment for drinking water. It's very effective. New technologies make it so it can be generated in situ from tablets, and the byproducts are harmless and not offensive.

Another one to look into is peroxyacetic acid. It's sometimes called paracetic acid. It's byproducts are water and vinegar, and it's extremely effective. In a previous life I used it as a final rinse for cut vegetables at a processing plant. It would be a great water treatment, but I'm not sure if the EPA has approved it for that application yet or not.
