Deep Well Disinfection: Sodium Hypochlorite Use, Post-Winter Water Smell & Annual Procedure

Hello everyone, I would like to ask how to disinfect the water after winter, the smell of sludge after 3 hours of pumping smells hardly noticeable, but I should carry out this procedure at least once a year. I can't find on the net how to do this and how much to add sodium hypochlorite and what to do next. Well from 2017, 125mm water surface at 14m and 32m deep.
I am asking for help from professionals or people who have had experience in this matter, thank you in advance

I am a theoretician, and I finished water technology about 20 years ago, but what I remember is that there is a problem with drills at home. Generally they are cleaned by intensive pumping. As for disinfection, the solution would be suitable to be administered under pressure. At home, you pour a disinfecting solution (mainly sodium hypochlorite, although there are now some preparations based on hydrogen peroxide and silver ions, probably such a fashion) prepared according to the instructions and turn on the taps, etc., until you smell chlorine, then turn off. Then a 24h break and intensive rinsing. It is appropriate to make the microbiological purity of water in the Sanepid or other laboratory to make sure that the treatment does not need to be repeated.

I will probably use sodium hypochlorite, so when I pour it into the well, I unscrew all the collection points until I feel chlorine and turn off, and the next day I do a few hours of pumping with all the outlets at the same time - this is what I understood, please confirm, a good tip also for other people who have wells.

You understood well, buddy. If anything, you can get hypochlorite in "Chemia" on Cobowa Street, they sell by kilograms, if you take your container it will be cheaper.

Exactly right, check the water in some lab. There can be several reasons for this smell of mud. By the way, when you have little children, check nitrates.

Do you have any filters?

Chloramine is used to disinfect water in deep wells, a bucket is poured into the well and after three days it is pumped out.
