I have a cistern that is fed by two wells. One is our own well, and one is a community well. I have a ballcock type manual float in the cistern, that lets in water when the level in the cistern drops by 6 inches or so. Both the wells have their own pressure tanks, but each well feeds the tank at different speeds. That is, our well has a low flow, and flows at about 4 gallons per minute. When I am able to get access to the community system, it flows in much faster.
I want to chlorinate the smelly, dark well water as it flows into the cistern (see attached pics), and I am wondering what type of flow switch or water meter I can get that controls the chlorinator pump, by flow. I want to inject an even amount of chlorine as I don’t want too much or too little. Also looking for a filter, after the cistern to take out the rust and sediment. Any ideas?

Thanks for emailing and sending in some pictures. You nailed it when you mentioned ‘water meter’ as what you need is a proportional feed controlled chlorinator with flow meter.
With this type of chlorinator, the chlorine bleach is precisely injected whenever the water flows through the flow meter. The flow meter, which looks like a water meter with a cable attached to the metering pump, will then energize the metering pump and begin injecting solution based upon the rate of flow.
After the cistern, your booster pump will pump the water through a Pro-OX iron filter, which will remove the dark color, rust and sediment. There would be little or no chlorine residual left in the water at this point, although you could use an optional carbon filter, after the iron filter if you wanted to.
Pro-OX Manganese Dioxide media is an NSF Certified natural high purity mineral that is used for removing iron, hydrogen sulfide, and manganese from water supplies. This media utilizes an oxidation-reduction reaction and filtration process similar to greensand, but at a much higher level of performance.
Pro-OX has a much higher surface area, is much more porous than Greensand, and also lasts much longer (usually 10+ years) compared to around 5 years typically for other filter media.
The result is very clean, odor-free, disinfected water free of sediment and iron with no chlorine taste or odor in the house.
