water chlorination system

[wv1720]

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.

The easiest thing to do might be to install a pool chlorine feeder in-line with the water line going to the holding tank. You can turn the chlorine flow way down by closing the valve almost completely. You can get the in-line chlorine feeders for about $50.

I looked at those. Might be able to make something work, but pools and spas use generally use sodium dichlor, whereas chlorine used for well water is calcium hypochlorite or sodium hypochlorite (liquid bleach). The plus to using a system using liquid bleach, is that it is cheap and readily available.

The venturi will need a pretty good flow rate to work correctly. It might be hard to control your feed rate with small or low flow rates.

we have our own water coming off the hills around my place, due to the alternating layers of clay, the water comes off the hill soaks into the earth and then drains into perforated pipe, this fills a well (well is there to collect sediment) and then this overflows into a larger plastic tank in the earth, the water runs down a pipe (with a pump to gain some decent pressure with a one way valve) it runs through a 10 micron filter and then a 1 micron filter, then it goes through a ultra-violet lamp to kill off any bacteria in the water, and finally through a water softener, (salt i belive) job done nice clean water, you could use reverse osmosis to remove all contaminants, but they are pricey, hope this bit of information helps, and no need for chlorine (nasty stuff)

The only safe method I am aware of is with a positive displacement injector pump...
do not inject dangerous chemicals into your drinking water with a system that could fail...

I have seen a lot of pellet drop systems that ended up not working. Now that I think about it I have not came across any of those for several years.

Liquid injection or gas injection is the only safe method I would trust...
Organic iron is a growing problem in a lot of areas... I am glad it is not around me... yet.

I recently heard about the UV systems. Almost sound to good to be true.

they are great, we change the filters once a year, although during periods of heavy rain the water can have a slight tint, and the UV bulb is changed once a year, im sure it would last a lot longer but as the performance is reduced over its lifespan its best to change it, im still alive and kicking and been drinking/washing in it for over 3 years, and no taxes/otherbills to pay and i use as much as i like

Actually mine uses bleach. Chlorine is much stronger than bleach and I tried cutting the concentration down but it didn't work well. You need to filter the chlorine or bleach out of the system after it's been filtered or you'll never be able to drink the water or bathe with it or do laundry.

If I were you I'd consider looking at injection pumps which regulate the flow pretty good.

Here's another thought.... What about ozone injection? My hot tub uses a corona discharge system to produce ozone for sanitation. I would think Ozone would be a little safer than chlorine and easier to manage.
