WELL WATER PURIFICATION: A hydrogen peroxide injection system offers two benefits for home water well systems. First, it sterilizes water by killing microbes and it does this without chlorine. Hydrogen peroxide injection is not only safe, but it offers health benefits, too. Second, hydrogen peroxide does an amazing job getting rid of the rotten egg smell of sulphur water when combined with a whole-house carbon filter. A carbon filter alone can’t do the job. My own system uses about $200 of hydrogen peroxide every two years, so it’s quite economical.

VIDEO TRANSCRIPT: 00:10 We’re here in my basement, and I want to show you my hydrogen peroxide injection system for our household water. You’re not going to see something like this too often, but there are some distinct advantages to this and I’m going to show you what they are and how the system works. It starts with this drum of 35% hydrogen peroxide. Now that’s pretty corrosive. If you were to touch that, you’d get a burn on your skin. So, it’s something to take seriously, but when it’s added to drinking water, to household water in small quantities, it does two important things. First of all, it kills all kinds of microbes. It sterilizes the water, and it does this without chlorine, which is a great thing, because hydrogen peroxide is nothing but H2O2. It’s like a water molecule with an extra oxygen atom tacked on, and that makes it highly oxidizing and that kills all kinds of microbes, so that’s one reason for hydrogen peroxide.
01:17 The second is that it’s super effective at eliminating sulfur water. That’s the rotten-egg smell that comes from water from some kinds of wells. We don’t have sulfur water problems here. I got this as a supplement. Our water tests fine, but I wanted to purify it, and so that’s why we’re using hydrogen peroxide here. It is the only way I know of to get rid of that rotten-egg smell, and it does that very effectively, too. Anyway, that’s the drum and hydrogen peroxide, full concentrate, 35% is drawn up through this pipe by this injection pump. This can be used for injecting a whole bunch of different things. This happens to be hooked up here, and when it turns on, it draws small quantities of hydrogen peroxide in here and it injects it in here.
02:16 This is the manifold that does different things in my water system. Incoming water’s coming through here and it rounds this bend and goes into the pressure tank. This is the pressure switch. As soon as the pump is energized, this injection pump is energized as well. When the submersible pump gets power, this gets power, and it starts running at the same time. The hydrogen peroxide is injected into the incoming water stream and it goes into the pressure tank with the water. Now this injector pump, it’s adjustable. This ring moves. I can rotate this ring to vary the amount of hydrogen peroxide that’s injected. What I’m aiming for is about 25 parts per million. I have some paper, like litmus paper, that tells me what the concentration is, and so at the current setting it’s what I want and it works quite well.
03:17 Now to be fully effective for removing sulfur in a sulfur water situation and for removing all kinds of smells and odors and tastes, I’ve combined the hydrogen peroxide system with this whole house carbon filter. This is filled mostly with granulated carbon, and the water flows through it and then it flows through the house. I can bypass this if I want so we can just get straight water with a little bit of hydrogen peroxide in it. There’s some people that’ll tell you that there’s health benefits to that, and I believe them, too. You can taste a little bit of a different taste when you’re drinking the unfiltered water, so most of the time we run it with the carbon filter in operation.
04:13 But that’s how it all works in a nutshell, and it certainly serves us well. It’s especially useful if you have a well and it has some kind of contamination, some kind of bacteria contamination, or you’ve got a sulfur water situation that you want to rectify.
