How to Make a Water Purifier

Do you know how to make a water purifier? Drinkable water is essential to health. Your body is 80% liquid and you lose water through perspiration, breathing and urination.

Dehydration poses a serious health risk as your body's efficiency begins to decrease with a dehydration of as low 6% of body weight.

If you are outdoors in the summer heat, your body can lose one gallon of water a day. In three days severe damage to organs can occur. The chance of heart attack and stroke increases as blood loses its density. The kidneys begin to fail and your brain may start to hallucinate.

Those are dire consequences directly due to lack of drinkable, clean water. Almost all rivers, lakes and reservoirs contain microorganisms and pollutants that are dangerous to our health.

These organisms cause dysentery, typhoid, cholera and hepatitis and can lead to death in someone with a compromise immune system. Parasites abound in untreated water and the risk is increased for children and the elderly.

The two common pollutants of water are natural and manmade. Natural pollutants are salts that leach from the earth and heavy metals while manmade pollutants include human waste, air pollution settling in open water and chemicals that drift into bodies of water when released in manufacturing processes.

Water Filtration and other Water Cleaning Methods

A water filtration method is simply a way to remove pollutants and impurities in water in order to provide water that is safe for human consumption. The size of the pores in the filter is critical as smaller impurities are more difficult to remove. Filters produced by manufacturers may be made of ceramic, fiberglass, carbon or products similar to compressed paper.

Pure silver is a water purification agent and has been used by many countries to disinfect water supplies for the populace. Only recently has the United States accepted pure silver as a water purification product.

Ultraviolet light (UV rays) is a method suitable for use in homes as a filtration method. Producing the light requires electricity which makes this method impractical for use anywhere power is not available.

How to Make a Water Purifier for your Home

In products meant to purify water at home, the priority is often on removing odors or tastes associated with a local water supply or with additives used to provide potable water in the area.

This is done through a filter system. If you are someone who likes to do things for yourself you can easily learn how to make a water purifier by learning to filter your own water supply.

Commercial water purifiers are readily available and the cost is not prohibitive. If you buy a refrigerator with the option of ice and water available on the door of the unit, there will be a filtration system installed. Changing the filter once a years is usually all that's needed to maintain the water purifier.

If you are a camper, you may need to know how to make a water purifier. A hand made filter can remove mud or other debris from water but it will not kill bacteria or remove contaminants. Making a water filter is not difficult but purifying water is a more complex issue.

Items Needed:
  • A container -2-3 liter bottle works well
  • Activated charcoal
  • Coarse sand
  • Fine sand
  • Course gravel
  • Fine gravel
  • Cotton

Cut off the bottom of the bottle. Stuff the pour spout at the top of the bottle firmly with cotton. Invert the bottle and add an inch of find sand on top of the cotton. Complete the filter by adding a layer of activated charcoal, layer of coarse sand, fine gravel and coarse gravel.

You are done with building a water filter. Pour water into the inverted bottle and allow it to filter through the layers of gravel, sand and charcoal and collect the newly filtered water as it drips from the cotton at the other end. This is a simple filter that will remove particulates to some degree but will not provide purification.

How to Make a Water Purifier that Yields Safer Drinking Water

A two step process can be accomplished that will remove the nasty impurities you can see in water and adds a second step that will yield water that is safe to drink.

You will need:
  • Two 3 inch sections of PVC pipe glued together
  • Window screen
  • Duct tape
  • Fine pebbles
  • Charcoal pellets
  • Cotton cloth or cotton balls

Use PVC glue to connect the two pieces of pipe. Cover one open end with the piece of window screen and secure it firmly with duct tape by overlapping the screen and wrapping tape around the pipe to secure it. The fine pebbles and charcoal pellets are widely available in stores that sell aquarium supplies.

Pour an inch of fine pebbles into the open end of the PVC pipe, ad a layer of charcoal pebbles on top and alternate the layers of pebbles and charcoal until the first pipe section is filled. In the top of the open pipe add folded layers of cotton or cotton balls to fill that piece of PVC pipe. The cotton will filter out larger particles from the water before the water reaches the layers of charcoal and pebbles.

Pour water into the open end of your newly created water filter and collect the clean water that drips out the screened bottom of the filter. This filter will remove debris and any mud or sediment from the water. You will be surprised at the different in appearance of the water that is released after passing through the filter.

The water is now cleaned of debris and particulates but may not be safe to drink. Add purification by boiling the water for five minutes. The heat will kill bacteria and organisms and yield water that is safe and clean to drink.

Summary

Instructions for how to make a water purifier are easy to find and not difficult to implement. If you are a hiker or camper it's a simple matter to make materials for making a water filter part of your camping gear.

Filtering water does not make it safe to drink. To purify water it should be filtered to remove impurities, sediment and debris and boiled for several minutes to kill any bacteria or organisms.
