For chemical methods of water purification, there are primarily two chemicals that are used. This guide covers one of them. In this water purification method, we’re going to cover how to purify water with bleach, which is one of the most common methods used in households for water purification.
Here's What We Cover In This Post
Bleach Chlorine Purification
- Bleach Basics
- 3 Step Process
If you’re unfamiliar with decontaminating water so far, you might be saying to yourself, “isn’t bleach poisonous to us?” Yes, indeed it is.
What we do to use bleach as chemical water treatment, is to add a small amount of bleach to the water. A small, small amount. It doesn’t take much. But we’ll cover the specific steps below.
If you’re going to use this method, you want to use the right kind of bleach. Don’t just use any bleach. Use the right kind. We want regular, good old fashion plain unscented chlorine bleach.
Also, look at the label for the active ingredient. Normally, bleach that is used in households will contain 5.25% chlorine. We’re looking for 8.25% of sodium hypochlorite.
Here are a few things to avoid when picking a bleach to use.
- scented bleaches
- any additional ingredients like added cleaners
Also, make sure the purpose of the bleach is for disinfection. The label will have this information.
Reminder: We’re looking for unscented bleach.
The actual chlorine is the ingredient that will be doing the work of disinfecting the water, so make sure not to use non-chlorine bleach.
Easy Instructions For Bleach Purification
The process is simple and straight forward. It just takes a few minutes to go through a purification cycle.
Using a medicine dropper is common practice for extracting the bleach to add to your contaminated water.
Add the correct amount of bleach to your water that needs treatment.
Mix the water and let the water stand for at least 30 minutes ideally.
Note: There should be a slight smell of the chlorine. If there isn’t, it’s likely not enough chlorine to get the job done.
Repeat the same dosage and let it sit again for an additional 15-20 minutes.
If the chlorine taste is too strong, then let it sit for 2-4 hours allowing it to be exposed to air for the duration. Pouring the water from the container to another clean container and back again, over and over helps as well. But it’s not necessary.
TIP: You can always filter the water before or after treating it with bleach to help get rid of the chlorine as best you can before consuming.
Here’s the step by step instructional video on the process.
Bleach is inexpensive and in abundant supply. If you don’t have any other resources to purify water, you can always go grab some bleach.
Just remember to use unscented bleach. Drinking water with perfumes in it will give you a bad day…
