You might think chlorine is the solution if you\u2019ve noticed an unpleasant, rotten-egg odor from your well water. But before you go down this route, take a moment to consider hydrogen peroxide water treatment as an alternative.<\/p>\n

Water containing hydrogen sulfide gas (\u201cH2S\u201d) has a unique \u201crotten egg\u201d odor, which is often present in both hot and cold water but may become more pronounced in hot water. This kind of water can discolor coffee, tea, and other beverages and alter the appearance and taste of cooked food.<\/p>\n

Hydrogen peroxide is an environmentally friendly and cost-effective way to eliminate this odor in your well water. Hydrogen peroxide is totally miscible with water, ensuring a thorough and even distribution throughout your water system.<\/p>\n

What is Hydrogen Peroxide Water Treatment?<\/h2>\n

 <\/p>\n

\"Close-up<\/p>\n

Hydrogen peroxide water treatment is a natural oxidation system that leverages the powerful oxidizing properties of hydrogen peroxide (H2O2) to remove contaminants and pollutants from drinking water. Unlike traditional chemical oxidants like chlorine dioxide and potassium permanganate, hydrogen peroxide is a natural metabolite that is both cost-effective and environmentally friendly.<\/p>\n

This method effectively eliminates the rotten egg odor caused by hydrogen sulfide and other impurities in water systems. By using hydrogen peroxide, you can ensure your drinking water is clean, safe, and free from harmful chemical residues.<\/p>\n

Benefits of Using Hydrogen Peroxide for Drinking Water<\/h2>\n

Using hydrogen peroxide for drinking water treatment offers numerous advantages. Firstly, it is a natural and non-toxic solution that leaves no chemical residues, ensuring your water remains pure and safe.<\/p>\n

Additionally, it is a cost-effective solution that can enhance the effectiveness of other water treatment methods. One of the standout benefits of using hydrogen peroxide is its gaseous release, which does not alter the pH levels of the water, making it a reliable choice for maintaining the quality of your drinking water.<\/p>\n

Hydrogen peroxide (H2O2) is a naturally\u00a0occurring chemical compound composed of two hydrogen atoms and two oxygen atoms that can be found in rainwater and some natural springs. It can also be produced synthetically and used for several purposes, including disinfecting surfaces and eliminating odors in well water.<\/p>\n

Hydrogen peroxide water treatment injects peroxide in precise levels into the water pipes as the water flows from your well. These systems can be installed at the wellhead or, if a proportional flow-sensor type peroxide system is used, on the incoming water pipes to your home. They are particularly effective in breaking down organic matter, which can significantly reduce the chemical oxygen demand (COD) in your water system.<\/p>\n

After the peroxide is injected, the water flows through a catalytic carbon backwash filter system to remove any remaining peroxide residual along with sediment and oxidized particles.<\/p>\n

What Size Catalytic Carbon System Will I Need?<\/h2>\n

Hydrogen peroxide catalytic carbon filtration systems for well water come in a range of sizes and capacities to suit different household needs.\u00a0 This backwashing self-cleaning catalytic carbon systems are sized in the cubic feet of media that is inside the filter tank.<\/p>\n

For example, a 1- or 1.5-cubic-foot catalytic carbon filter is typical for a small home. For larger homes a 2 or 2.5 cubic foot carbon system with 1-inch pipe fittings is typically used.<\/p>\n

Because the carbon is a special type of catalytic carbon, a reaction takes place on the surface of the carbon. The carbon doesn’t get used up or worn out like standard carbon. Typically, the carbon inside will last four to six years, depending on backwash frequency and the severity of the hydrogen sulfide.\u00a0 Fortunately, it’s easy to dump out and replace.<\/p>\n

Choosing the right combination of flow rate and tank size ensures your system can handle peak water use while maintaining efficient filtration and effective peroxide injection.<\/p>\n

How Can I Turn On and Off My Peroxide Pump Automatically?<\/h2>\n

The injection pump needs to be installed so it turns on and off automatically each time the well pump turns on or water flows.<\/p>\n

1. Wire the peroxide pump to the same circuit as the well pump via the pressure switch.<\/h2>\n

Standard Installation: It is wired to the pressure switch to turn on and off with the well pump. NOTE: A contact tank is not needed in most applications.<\/p>\n

\"Diagram<\/p>\n

2. Wire to a flow switch.<\/h2>\n

The flow switch is plugged into a wall outlet, and the peroxide injection pump is plugged into an outlet on the flow switch. When water flows, the peroxide pump is turned on and off, and the pump is turned off when water stops flowing.<\/p>\n

3. Use a proportional feed-type pump.<\/h2>\n

This type of peroxide pump works in conjunction with a flow meter. It is wired so that the pump injects more or less peroxide based on the water flow.<\/p>\n

This also makes it easy to install your peroxide system without requiring an electrician.<\/p>\n

When properly maintained and managed, the well water’s hydrogen peroxide level can be precisely controlled.<\/p>\n

Install a Catalytic Activated Carbon After Peroxide Injection System<\/h2>\n

In addition to being economical and easy to use, one key advantage of these systems is their ability to reduce problems associated with chlorine-based treatments, such as corrosion, taste and smell issues, and potential health risks.<\/p>\n

Best of all, a retention tank is usually optional when using hydrogen peroxide for odor removal, rather than something the process requires for contact time; once the oxidized particles settle out of the water, they can be filtered out with a catalytic carbon backwashing filtration system. Some installations still do better with one \u2014 to settle out sand, to handle high iron, or to work around an unusual plumbing layout \u2014 so whether a tank earns its place depends on the well and the system it feeds.<\/p>\n

The actual treatment procedure is simple. Whenever the well pump turns on, a metering pump automatically inserts a tiny amount of hydrogen peroxide in front of the pressure tank.<\/p>\n

Use a Catalytic Carbon Filter After Peroxide Injection<\/strong><\/p>\n

The back-washing catalytic carbon filter system<\/a> is installed after the pressure tank.\u00a0 The result is clean, odor-free water throughout the home.<\/p>\n

Flow Sen<\/strong>sor Systems Allow Peroxide Systems to Be Installed After Well<\/strong><\/p>\n

In some cases, it’s not practical to install the peroxide injection point near the well, or perhaps you are on a shared community well and prefer to have the system right where the water enters the home.<\/p>\n

In this case, a flow-based system can be used. This system uses a proportional flow meter to control the peroxide injection pump.<\/p>\n

As soon as there is flow, the peroxide pump injects a small amount of hydrogen peroxide based on the speed of the water flowing through the pipe.<\/p>\n

Proportionally fed hydrogen peroxide products offer owners a convenient way to inject hydrogen peroxide as the water enters the household plumbing system and are very easy to set up and maintain.<\/p>\n

Can You Use a Water Softener with Hydrogen Peroxide?<\/h2>\n

Yes.\u00a0 See this diagram.\u00a0 Install your water softener after the catalytic carbon backwash filter.<\/a><\/p>\n
