Designing a Walter Filtration Device

Designing a Walter Filtration Device



Of all the elements of survival, water is one of the most important things to consider.  Depending on your resources, there are several different ways to purify water.  One of the easiest ways to collect water from your surroundings is to place a discarded plastic bag around a branch of a plant.  This will not only able you to collect morning dew, it will also allow you to collect water throughout the day.  As the sun heats up the plant, it evaporates water.  The water is then trapped in the bag.  The benefits of this method is its ease in setting up and taking down.  The drawbacks are the quantity of water this allows you to collect.  This is a good idea for short term water use, but will not be sustainable over a long period of time.    


Another device that is relatively easy to set up is a natural filtration system.  As the picture below indicates, it consists of three layers of material.  It is best to repeat these layers multiple times.  If the charcoal that is being used is activated charcoal (see my article on activating charcoal), then it is much more effective.  This system will purify water as long as the water is not highly or very contaminated.  The benefits of this system is that it is easy to set up and use.  The drawbacks is that if your water is pretty dirty to begin with, it may not eliminate all of the contaminates.  



Creating a solar still is a good option for long term water purification.  There are many different designs out there, but they all consist of similar principles.  It essentially traps evaporated water and collects it.  This is similar to the first idea, but it involves a more permanent setup.  The solar still will eliminate almost all contaminates.  The drawbacks are in the time amount of time it takes to get a good quantity of water.  Another more simple method is to take a bottle of water and leave it in the sun.  There is no real science to this, but the sun will eventually kill all of the harmful bacteria inside.  Since this is not a exact method, it should be seen as a last resort.    







Another way to purify water is chemically.  Two chemicals that are readable accessible are bleach and iodine.  If your water is cloudy, funnel it through a cloth or filter.  If you do not have a filter, then wait until the water settles and then scrape the clean water off the top.  For iodine, place 5 to 10 drops per 32 fluid ounces or 1 liter (the amount of drops depends on how clear the water appears).  Be sure to use iodine that has a 2 percent tincture.  Let water stand for 30 minutes before drinking.



Chlorine is another great way to purify water chemically.  There are many different thoughts on how much chlorine is needed, but according to the EPA, 8 to 16 drops or 1/8 to 1/4 teaspoon, should do the trick.  Like iodine, let the water sit for 30 minutes before drinking.  The chlorine smell in the water should disappear after a few days, but it is harmless.  One great thing to keep on hand is pool shock.  This is sold at most stores as pool supplies.  It is essentially chlorine in concentrate.  With just a bucket of this, you can make hundreds of gallons of chlorine, and consequently, you can treat thousands of gallons of water.  

  

Boiling water is always a good way to purify. It is best to boil water for 1 minute at sea level, adding 1 minute for each additional 300 meters above sea level.  Or boil for 10 minutes no matter where you are.  Make sure the water is boiling before you start counting the time.  There are a lot of websites that insist that water should be boiled longer and, although it will not do any harm, it is not necessary.  This is the safest method but comes with its own drawbacks, such as needing a constant heat source.

How to Build 880 Gallon Water Storage in a Small Space

How to Build 880 Gallon Water Storage in a Small Space



The first step is to come up with a design.  As you can see from the picture, I made wood pillar between each tank of water.  Using formulas online I found to figure out the strength I would need (see the following website: https://www.cecalc.com/WoodDesign/WoodTension.aspx) I was able to find out how much I would need to support my load.  A gallon of water weighs about 8 lbs and each of my blue barrels has 55 gallons (8 X 55 = 440 lbs per barrel).  My design holds 16 barrels (16 X 440 = 7040).  I decided to be safe, I would make sure my design could hold 10,000 lbs.


Once I had the basic design finished, I reinforced each pillar with an additional 2x4 and added woold panels to each side.  I then anchored the entire platform to the wall on two points--the wall is an outside wall made out of concrete. 


To make sure the barrels did not roll around, I cut barrel shapes into the supporting beam of the water barrels.



This picture below shoes the reinforced pillars.


This is the completed structure with 16 full barrels.



 This project cost me around 400 dollars and only a day to build.  It was a simple, fun project and does not take that much space.

Edible Insects




Edible insects; you may feel that these two words do not even belong in the same sentence. You have every right to be skeptical. In all probability, you have never deliberately ate an insect. However you have probably inadvertently consumed over a pound of insects in your lifetime.
Your insect consumption adds up. Flour beetles, weevils, and other insect pests that infest granaries are milled along with the grain, finally ending up as tiny black specks in your piece of bread. Small grubs and other tiny insects can be found in your fruit and vegetables. Insects are especially common in canned and other types of processed food, and even in certain beverages; I once went on a tour of an apple orchard and while the group was viewing the area where they separate the rotten and bug infested fruits from the good ones, I asked the tour guide what they did with the bug infested apples. She told me that they use them to make cider; waste not, want not! It is virtually impossible that you have not ingested insects in one form or another during your lifetime. And it probably did not harm you, but instead did you some good by providing extra protein in your meal! 

There are a number of points that I would like to make:
·         Some insects are edible. In fact, most insects are edible, but there are a few species that are especially palatable, nutritious, and easily obtainable. I will concentrate on these.      
·         Many species of insects are lower in fat, higher in protein, and have a better feed to meat ratio than beef, lamb, pork, or chicken.
·          Insects are tasty. Really! Even if you are too squeamish to have them as a main dish, you can make insect flour and add it to bread and other dishes for an added protein boost.          
·         Insects are easy to raise. There is no manure forking. No hay bale lifting. No veterinary bills. You can raise them in an apartment without getting complaints.          
·         Insects are beautiful. I think that all insects are beautiful, but most people I know will marvel at the iridescence of a butterfly, but shudder at the striping of a mealworm.          
·         Most people do not mind butchering insects. The butchery of insects is very simple compared with that of cattle or poultry, and nowhere near as gory.·          
·         Raising insects is environmentally friendly. They require minimal space per pound of protein produced, have a better feed to meat ratio than any other animal you can raise, and are very low on the food chain. They are healthy, tasty, and have been utilized for the entire history of mankind (after all, it is easier to catch a grub than a mammoth).
       
·         Also, as far as I know, no animal rights activists object to the eating of insects. You don't need to destroy any wildlife habitat to eat insects, and you can incorporate insects and earthworms into a recycling program......vegetable waste in, yummy insect protein out.

O.k., I admit the slight possibility of disadvantages...   The only real problem you may run into while utilizing insect protein is the lack of social acceptance. That is why we sensible insect eaters must make it our duty to educate the public about the value of insect protein. You may encounter widespread disbelief, "You're kidding me. You don't eat insects!", revulsion "Yuck! You eat insects!?! ",  Press on! Remember, insects are the food of the future, and you are paving the way for future generations.

Is there a better name than insect eating? 

Why yes, there is. The word is Entomophagy. You would think that a word this melodious would be in common usage, but sadly this is not the case. In fact, you probably have never heard this word before (unless you happen to be a friend). Find ways to interject the word entomophagy in casual conversation, as in: "Did I ever tell you about the array of culinary options revealed through the study of entomophagy ?"
Other Random Entomophagy Factoids 

In case you need a little more persuasion:   
There are 1,462 recorded species of edible insects.  Doubtless there are thousands more that simply have not been tasted yet. 100 grams of cricket contains: 121 calories, 12.9 grams of protein, 5.5 g. of fat, 5.1 g. of carbohydrates, 75.8 mg. calcium, 185.3 mg. of phosphorous, 9.5 mg. of iron, 0.36 mg. of thiamin, 1.09 mg. of riboflavin, and 3.10 mg. of niacin.

Compare this with ground beef, which, although it contains more protein (23.5 g.), also has 288.2 calories and a whopping 21.2 grams of fat!
 

How to Obtain Edible Insects 

By far the most difficult part of attempting any insect recipe is acquiring the necessary ingredients. Insects are rarely sold in supermarkets, nor, aside from various novelty items, are there many pre prepared insect food products. Therefore, those who wish to eat insects must acquire them either by catching insects in the wild, by buying insects from pet stores or bait shops, or by raising their own.

Catching insects in the wild, unless you're fortunate enough to live in a rural area, is a laborious and potentially dangerous task. I advise this type of insect collection only if you're sure that the insects you're collecting are edible (doyous...), and that the area where you're collecting is free of pesticides. Cicadas, field crickets, grasshoppers, grubs, tomato horn worms, and so forth, are among the edible insects one is likely to find on such hunting expeditions.


Buying insects is the easiest way to get edible insects, but it is also the most expensive (ain't it always the way?). Most pet stores and bait shops carry crickets and mealworms, two of the most easily raised and prepared insect species. You can also buy these insects in bulk from various insect suppliers. The only preparation that you need give to insects acquired in this manner is that of feeding them for a few days on fresh grain; most insects you buy at bait shops or pet stores have been eating newspaper, sawdust, or similarly unsavory packing material, which, while completely harmless, might affect the insect's taste if you ate them while the material was still in their digestive tract.

Raising insects, in my opinion, is the optimum way of ensuring a steady supply of palatable insects. While not entirely as convenient as simply popping into the pet store whenever you need insects, it is far cheaper, more environmentally friendly, and more rewarding in the long run. 

How to Prepare Insects for Cooking 

Those who are accustomed to eating animals probably know that most animals must be killed, cleaned, and cooked before one can eat them. The case is similar with insects. While there are many people in other countries who prefer to eat insects live and raw, and while it is true that you could probably get the most nutrients that way, I prefer food that won't crawl off my plate. I have tried eating live ants and mealworms, and in fact present a "recipe" for live insect consumption below; however, I would advise that beginning insect eaters start with cooked insects.

To prepare a batch of crickets or mealworms:

Take the desired quantity of live insects, rinse them off and then pat them dry. This procedure is easy to do with mealworms, but fairly hard to do with crickets. To do so with crickets, pour them all into a colander and cover it quickly with a piece of wire screening or cheesecloth. Rinse them, then dry them by shaking the colander until all the water drains. Then put the crickets or mealworms in a plastic bag and put them in the freezer until they are dead but not frozen. Fifteen minutes or so should be sufficient. Then take them out and rinse them again. You don't really have to clean mealworms, though if you want, you can chop off their heads. Cricket's heads, hind legs, and wing cases can be removed according to personal preference; I like doing so, since cricket legs tend to get stuck in your teeth. You are now ready to use the insects in all kinds of culinary treats!
Mealworm Chocolate Chip Cookies

 1/2 cup butter 
1/2 cup brown sugar 
1/2 cup white sugar 
1 egg 
1/2 teaspoon vanilla 
1 cup all purpose flour 
1/2 teaspoon salt 
1/2 teaspoon baking soda 
1/2 cup oats 
1/2 cup chocolate chips 
1/4 cup mealworm flour

Cream butter well, then mix in sugar, egg, vanilla flour, salt, baking soda, chocolate chips, oats, and mealworm flour. Drop batter by the teaspoonful on a greased cookie sheet. Bake for 10 minutes at 375 degrees Fahrenheit. This recipe doesn't have much in the way of palpable insect content, but is an excellent way to introduce others (or yourself!) to entomophagy. Even many rather squeamish people will try mealworm cookies, since the cookie format doesn't look "gross" to most people, and since it is rather difficult to actually taste the mealworms, though they enrich the cookie with a somewhat nutty flavor and extra protein.

To make insect flour:

Spread your cleaned insects out on a lightly greased cookie sheet. Set your oven 200 degrees and dry insects for approximately 1-3 hours. When the insects are done, they should be fairly brittle and crush easily. Take your dried insects and put them into a blender or coffee grinder, and grind them till they are about consistency of wheat germ. Use in practically any recipe! Try sprinkling insect flour on salads, add it to soups, your favorite bread recipe, on a boat, with a goat, etc.


Chocolate Covered Crickets
25 adult crickets 
Several squares of semisweet chocolate

Prepare the crickets as described above.  Bake at 250 degrees until crunchy (the time needed varies from oven to oven). Heat the squares of semi sweet chocolate in a double boiler until melted. Dip the dry roasted crickets in the melted chocolate one by one, and then set the chocolate covered crickets out to dry on a piece of wax paper. Enjoy! This is a little time consuming to make, but definitely worth it...the crickets are deliciously crunchy!
Ant Brood Tacos
  2 tablespoons butter or peanut oil? 
1/2 pound ant larvae and pupae 
3 serrano chilies, raw, finely chopped 
1 tomato, finely chopped 
Pepper and Cumin, to taste 
Oregano, to taste 
1 handful cilantro, chopped 
Taco shells, to serve

Heat the butter or oil in a frying pan and fry the larvae or pupae. Add the chopped onions, chilies, and tomato, and season with salt. Sprinkle with ground pepper, cumin, and oregano, to taste. Serve in tacos and garnish with cilantro. (Not living in an area exceptionally prolific with ants, I have never been able to try this recipe. But it sounds perfectly delicious! I found it in 'Creepy Crawly Cuisine', an excellent recipe book.)

"Natural Style"
         As many mealworms as you can sanely eat 
Open mouth.  Insert live mealworms.  Chew.  Swallow.

You can eat almost every kind of edible insect raw; however, this method of eating insects should only be performed on insects that you keep yourself or know are free from pesticides. Do not snag passing cockroaches, ants, or termites in an urban area unless you have developed a natural immunity to pesticides. And don't forget to wash your insects before eating them!

Raising Mealworms 

Raising mealworms (Tenebrio Molitor) is quite easy and recommended for the beginner. Simply take a flat plastic tub with a lid, fill it with an inch or so of oats or other grain, put in a slice of potato, carrot or other hard vegetable as a source of water, and then deposit your mealworms!

Make sure to replace the slice of potato fairly frequently, otherwise you will be growing mold instead of mealworms.

The mealworms you get at the store are in their larval stage, and it may be a few months before they mature into beetles, so be patient. 100 mealworm larvae is a good colony start if you are not going to be eating them very often. If you wish to make insect protein a regular part of your diet, you can obtain mealworms in bulk from reptile food supply companies and start a large colony (5000 or more is the way to start in this case).

If you have an ant problem in your area, you should float the mealworm tub in a dish of soapy water to prevent ants from infesting your grain. However, unlike crickets, mealworms are unlikely to escape unless you are hideously careless.
Raising Crickets 

Crickets are quite easy to raise and prepare, and the main problem is making sure that they don't escape. Crickets can be kept in any fairly large container with high sides and a tight fitting lid. An aquarium is a good choice. Put a couple inches of potting soil on the bottom of the container.
This will be where the crickets deposit their eggs. Put several egg cartons in the aquarium for the crickets to roost on. Then, place a small container of grains and vegetable scraps in for food, and a container of moist cotton balls for water. Add 50-100 crickets. Mist the potting soil lightly every few days, and make sure that the crickets always have fresh food. You can probably start harvesting the crickets within a few months.

Crickets are escape artists!!! It is a good idea to put a rock on top of the lid to ensure that you don't accidentally knock it off. It is also a good idea to float the container in a tub of soapy water. Unlike mealworms, it is almost impossible to recapture crickets once they escape, and crickets may start infesting your house if they get out while you're on vacation (don't panic, though... they rarely cause any real damage to food or furnishings). I would really recommend that you start with mealworms if you are new to insect raising.
