Cheap easy and effective way to filter water
Mind you I would still boil this water but I’ve used this before and it works well
Just a topic for discussion
Cheap easy and effective way to filter water
Thats pretty neat, how confident would you be in drinking eater filtered like this?
I’d say it’s better than nothing, but filter and boil should be pretty damn good.
I have filters just never messed with homemade stuff like this.
I have a few as well
Like Brian said I would filter then boil to be sure
But it definitely works well
It was my hope scince we have a few prepping threads that people would discuss this topic not all of us here are prepped so to speak and in a pinch this works well
No it makes sense and is a cool topic. I might try it out sometime.
as long as you added about 3 caps full bleach per litre you would probably be okay with it - (wouldn’t trust the grass 100%).
Can we turn this into a general water filtration thread or would you rsther keep it on topic about yhe homemade filteration?
Most filters are made in a similar fashion. I mean layered with different material for the water to pass through. If you think about underground water sources, they are filtered through rock, clay, sand, etc. I’d imagine the thicker your layers the more effective.
Feel free please I have 3 pro pure filters
What does anyone else use
Simple cost effective way for people who don’t have filters here
Well water is my favorite water lol
I live in dairy farm country, so any nearby surface water probably has a heavy dose of animal manure. For me, disinfectant tablets and boiling are probably the best methods for preventing the Hershey squirts.
Boiling should be in everybody’s plan
Bleach has a limited shelf life but you can get around that. Just be careful and read labels carefully, also research safe storage, this stuff is dangerous.
from the article:
"One of the main components that you’ll want to have around the house (or apartment) during a SHTF situation is chlorine bleach. Not only can it be used for cleaning water (although boiling is hands down more effective and healthier) it is excellent for keeping things sanitary.
Unfortunately, the average shelf life of liquid bleach (being stored between 50 and 70 degrees Fahrenheit) is around 6 months. After that, bleach will lose 20% of it’s strength at around the year mark and then 20% each year after that. So if you’re not vigilant about keeping it rotated, chances are when you need it for disinfecting water or to keep things clean you’ll be fresh out of bleach and luck.
There is a better option. What if you could make your own fresh chlorine bleach that could be used for both keeping things sanitary and will disinfect water? Here’s how:
How to Make Chlorine Bleach
Before we go into how to make it, I just wanted to point out the differences between this homemade chlorine bleach and your standard household Chlorox variety.
First off, liquid chlorine bleach is a solution made from mostly water and 3-6% Sodium Hypochlorite. This homemade variety is made from Calcium Hypochlorite which you can easily find as “pool shock” at your pool-supplier store or Walmart. Both are used throughout the world for water purification and are the main chemicals in standard household cleaning products.
THE BENEFIT OF CALCIUM HYPOCHLORITE
The major benefit of using Calcium Hypochlorite over Sodium Hypochlorite is shelf life. Calcium Hypochlorite (pool shock) is sold in a solid granular form and has a 10 year shelf life when stored in a cool, dark place. This will easily meet your long-term storage needs.
The other benefit is the amount of available chlorine. The concentration of chlorine is much higher with Calcium Hypochlorite. For example, a small 1-pound bag of calcium hypochlorite can disinfect up to 10,000 gallons of drinking water. That’s around 5 gallons/day for one person for 5 1/2 years! Not bad for only 1 lb of granules.
MAKING CHLORINE BLEACH
To make a chlorine bleach solution using calcium hypochlorite, here are some formulas I got from the Army Technical Bulletin entitled, “SANITARY CONTROL AND SURVEILLANCE OF FIELD WATER SUPPLIES” (TB MED 577).
From the Army manual, to make a concentrated chlorine solution that you can use for disinfecting water (or to be used in maintaining a clean and sanitary living environment), you’ll want to use calcium hypochlorite that has around 70% available chlorine.
If you’re buying pool shock, on the back of the bag it will tell you what percentage of chlorine is available. The one I use is called “Zappit 73 Pool Shock, it is pure calcium hyphochlorite that contains up to 73% available chlorine and sells for around $5 for a 1lb bag.
To make the homemade chlorine bleach solution, you’ll need to do the following:
- Mix 2 level Tablespoons of Calcium Hypochlorite to 3 cups of water.
After you’ve made your stock of chlorine solution, you’ll want to follow the formula from the Army Technical Bulletin in determining how much of the above stock chlorine solution you’ll need for your desired number of gallons of water to be disinfected. *Note: I’ve updated the formula to calculate the same concentration that household bleach has. If you have questions, fire me an email and I’ll be more than happy to explain the math.
mL of stock chlorine required = (desired concentration (mg/L)*number of gallons to be treated)/18.12
The desired concentration refers to how much chlorine in mg/L you want the disinfected water to have. A recommended amount is 7 mg/L of concentration. This equates to adding 8 drops of household liquid bleach to 1 gallon of water (the recommended amount when disinfecting water with household bleach).
Given these amounts, if you wanted to disinfect 1 gallon of water with the homemade chlorine solution, the formula would be as follows:
This equates to .38mL or 8 drops of the concentrated solution per gallon of water. Just like normal household bleach!
So the 3 step process is as follows:
- Place 8 drops of homemade chlorine bleach in 1 gallon of water
- Let stand for 30 min
- If water is still cloudy, repeat steps until clear; otherwise it is ready to drink
Keep in mind, that once the homemade chlorine bleach is made it will follow the same shelf-life limitations as standard household liquid bleach. So be sure to only make amounts you will be using within that time frame."
Good info for bleach making.
You know another thing to consider here is the boiling. Not trying to take this off-topic, but without a means of making fire and enough fuel, you can only boil water for so long. How many people stock enough fuel sources for that? How much and what are the best ways to do that?
the best is to chemical disinfect - ie use bleach or chlorinated tablets (by the way a good source with a long shelf life is swimming pool / hot tub stores for the pucks)
You need some test strips and if you over dosed the water all you have to do is let it sit open to the air for 24 hours
Good info! Thanks for sharing.
