- Guest-post from the wife on advice r.e. getting used to having firearms in the home (she grew up with the "guns are dangerous/evil/scary" stigma). Should be a good post to pass along to anyone intimidated or concerned about guns.
- My take on an Urban Pocket Survival Kit; there's lots of wilderness survival altoid/pocket kits out there, I wanted to do something different! Been spending way too much time trying to make this relevant and useful - getting close!
- A post on my completed First Aid Kit (waiting for some components in the mail).
- Maybe some complaining about how stupid the cast of The Colony is this season (short version: they're morons).
- And hopefully some other cool stuff.

Working on projects...
Blog's been a little slow the past few days; my apologies! I'm working on several projects and waiting for things to reach a 'finished' place before posting. They should get there next week-ish. Here's what's in the pipeline:

Two projects me and mine are working on. Please give me some intel. I have purchased 3" tabs of solid chlorine to make bleach (so that water purification is cheap and portable). Also, making your own charcoal (carbon/not activated) is easy and helpful to any long term water system. I have done the charcoal side of things (manufacture and use) many times with GREAT success. Trial and error makes for great practical knowledge. But what I really lack is the measurment needed for adding the dry powederized Chlorine to water (distilled???) to make bleach. Could we research and discuss? Thanks for all you do everyday. Faithful reader.
ReplyDeleteAlso, difference in application between sodium and calcium regarding chlorine might need discussion. The science guys seem to hold the intel too tightly to the chest, in fear we might not wear gloves and face/respiratory shields. Thanks so much!
ReplyDeleteHere's an informative article that I found.
ReplyDeleteAnd a blurb from here:
How much chlorine dioxide should be dosed?
For the pre- oxidation and reduction of organic substances between 0,5 and 2 mg/L of chlorine dioxide is required at a contact time between 15 and 30 minutes. Water quality determines the required contact time. For post- disinfection, concentrations between 0,2 and 0,4 mg/L are applied. The residual byproduct concentration of chlorite is very low and there are no risks for human health.
Now we are getting at my dillema. There, you mentioned Chlorine Dioxide. And I mentioned Chlorine in a Sodium or Calcium form. What we ALL need is a simple breakdown for us all to use. A specific solid powder form that we can all read on the label, add X amount to one pint or gallon to make bleach. I do know that if you start with microbiologically safe water, such as tap water; then you can add 5-7 drops of chlorine bleach (liquid) for long term storage (in food grade plastic-clean, cool and in the dark). I will do some more research myself and see what I can find with the formula to make bleach.
ReplyDeleteThe specific process I am trying to perfect is as follows: I have my own granulated charcoal that I made. Also, I have solid pool chlorine tabs (99% solid chlorine). Also, I have clean food grade containers and pre-filtering fabrics. And, of course, WATER that needs treating for personal use. With those minimal items, I want to: make up liquid chlorine bleach, add liquid bleach to pre-filtered water, let stand/mix/stand, add charcoal (to absorb and neutralize chlorine), pour and filter out charcoal, end up with delicious and clean/safe drinking water. I will get back to work on my research. Thanks for the post!

ReplyDelete"You can use granular calcium hypochlorite to disinfect water.
Add and dissolve one heaping teaspoon of high-test granular calcium hypochlorite (approximately ¼ ounce) for each two gallons of water, or 5 milliliters (approximately 7 grams) per 7.5 liters of water. The mixture will produce a stock chlorine solution of approximately 500 milligrams per liter, since the calcium hypochlorite has available chlorine equal to 70 percent of its weight. To disinfect water, add the chlorine solution in the ratio of one part of chlorine solution to each 100 parts of water to be treated. This is roughly equal to adding 1 pint (16 ounces) of stock chlorine to each 12.5 gallons of water or (approximately ½ liter to 50 liters of water) to be disinfected. To remove any objectionable chlorine odor, aerate the disinfected water by pouring it back and forth from one clean container to another."
Above "quoted" material appears to have come from a gov't website, so it appears to be well researched and credible. I will run some trials with it and advise.
Additionally, it looks like the process is best done from scratch and as you need a batch; rather than making thousands of gallons at a time for months of storage. Also, it looks as though it would be wise to keep the dry chemical sealed up and separate from any other chemicals such as sulfur and brake fluid. The vapors of the chemical can permeate food stores and ruin them. SEPARATE for both reasons. Explosions are not an acceptable side effect of making clean water.
