How to Purify Water With Charcoal
Cleaning drinking water is a must for a body to function. Whether it is waste removal or digestion, water has a crucial role in ensuring a healthy body. Nevertheless, other additives and toxins find ways into the waterways and also in the drinking water. However, one can ascertain clean drinking water by installing a water filter.
The commonly used filters are the charcoal filters in the home. They are natural, clean, and are full of health benefits.
What is charcoal and how does it work?
Charcoal is a fine black powder made from charcoal bone, coconut shells, peat, petroleum coke, coal, olives, or sawdust.
Carbon activation is a process by high temperatures to generate a carbon more porous than normal. The porous texture of charcoal has a negative electrical charge, which causes it to attract positively charged molecules, such as toxins and gases.
The activation of the carbon produces an excellent filtration surface and allows it to have a great capacity to absorb impurities from the water. During the absorption process, matter adheres to the surface of an absorbent, in this case, activated charcoal. Thanks to this absorption it is that the activated carbon becomes very retaining capacity.
Activated charcoal works by trapping impurities in water such as solvents, pesticides, industrial waste, and other chemicals. That’s why it’s used in water filtration systems around the world. However, it does not trap viruses, bacteria, or minerals in the water.
Can You Purify Water With Charcoal?
Charcoal is used in water filters, but it is not the same as your barbecue bricks. The water filters use activated charcoal that is available as loose beads or is pressed in the form of a solid block. Charcoal activation is accomplished through the superheating process of charcoal at more than 1000F temperatures without oxygen. The charcoal is treated chemically with nitrogen and argon. It is followed by superheating as a second-round having the inclusion of steam and oxygen to develop a porous structure. The activated charcoal’s porous structure is the key factor making charcoal water filters effective.
Activated charcoal works following the adsorption process. The adsorption process is to bind chemically than physically. The activated charcoal pores increase the charcoal surface area up to additional 2000 square meters and it improves drastically its adsorption efficiency. Activated charcoal offers for water filters a great material. It is effective and natural at removing from the water many toxins, such as chlorine and volatile organic compounds, without using chemicals or stripping minerals and salts from water. Carbon-based impurities in the water attract the charcoal carbon and it bonds readily to these impurities. Thus, other compounds, relying on the polarity and molecular weight do not attract the carbon and pass through the filter.
As the process results in forming bonds between compounds, the impurities are kept in the filter. The charcoal filters also need replacement once the pores are filled. Thus, replacing and maintaining charcoal filters is inexpensive and easy to do, that charcoal filter is highly popular among households.
Simple steps of charcoal-based water purification filter-making
Materials needed- Charcoal, sand handful, canteen, survival knife, empty plastic bottle, pebbles handful, clean cloth piece, and water carrier.
Making a charcoal-based water purification filter
- As the first step, collect all the materials needed. Use a charcoal piece from a campfire. You may also come across some fire extinguished pit, thus you can save your trouble of initiating a fire.
- As the second step, use a survival knife and cut the plastic bottle bottom, and do not discard it.
- In the third step, keep the cap on; put some pebbles inside the bottle.
- Use the knife pommel to stuff pebbles, it will be simpler.
- Add sand as a layer. Again using your knife back end, ensure it is neatly layered and looks tidy.
- Add a cloth piece and properly arrange it.
- Toss charcoal and if required you can powder it by smashing it so that it fits inside the bottle.
- Again add a piece of cloth to it and add more sand.
- Put some pebbles on it and you are ready to go.
Now as you pour water, it filters through this charcoal-based water filter purification system.
Water purifiers for domestic use
Water purifiers are devices for filtering salts and other dissolved substances in tap water. In this way, its salinity is considerably reduced, achieving a more pleasant taste and eliminating possible odors.
There is a wide variety of purifiers on the market, but there are two basic types: those that connect directly to the tap and pitcher types.
Pitcher water purifiers usually have a capacity of between one and two liters of water and fit perfectly in the fridge. Its use for the home is highly recommended because it eliminates water hardness, reducing the risk of developing stones in the kidneys.
On the other hand, tap water purifiers, offer a greater number of features. Being directly connected to the tap ensures that all water coming out of it is free of impurities. Besides, most of them have the choice between purified and unpurified water.
Both types purify the water using a filter that must be changed according to the manufacturer’s recommendations. Note that after the set time, the filter will stop working properly.
Charcoal filter Benefits
Retains good stuff
The benefit is that the drinking water has many minerals, besides hydrogen and oxygen. Many impurities and chemicals are making up the water composition. The water filters remove efficiently these impurities, chemically or mechanically. They remove a lot of ions and minerals healthy for bodies. The chemical composition and the activated charcoal structure, have filters attracting and absorbing unhealthy organic compounds. Thus, it allows the minerals to be present in the water. It does not eliminate the microorganisms or pathogens, thus making charcoal to be the best to use in conjunction with any other filter.
Water is healthier
The charcoal filters remove nasty stuff and add things into your water back, making it healthier. The benefit of adding activated charcoal is that it adds important minerals such as iron, magnesium, and calcium into your water, thereby improves water quality.
People dislike the tap water taste and keep complaining the taste is metallic. Some also feel there is an off-putting aroma. The taste is due to the additives, such as chlorine, that are added in reservoirs to kill pathogens and bacteria. It is essential in the interest of public health, but it also means avoiding drinking tap water, as there is a risk for dehydration. This results in ending buying the plastic bottled water that is bad for the environment. Charcoal filters adsorb nasty-tasting chemicals that eliminate odors effectively, thereby making your drinking water palatable.
It is inexpensive
The water filtration systems are sometimes very expensive. It cannot be ignored as they are essential. They become a crucial investment for the goodness of your health and home. The charcoal filters are comparatively cheap, it is easily available, inexpensive to produce and the savings can be passed to the consumers down.
Easy to maintain
The filters require replacement even after the charcoal is used. The benefit is that the parts for replacement are cheap. They are also easy to install and source. The charcoal water filter is replaceable twice annually, once in six months. Conversely, it relies on the water amount to use and also on the water quality. If you are uncertain, you may look at the water clarity, observe the taste of the water for changes or consider if the water flow rate has reduced. In case you notice anything there may be a need to change the filter.
The charcoal water filters are the popular water filter types in the market for good reason. Using activated charcoal has ecological, economic, and health benefits. You may consider the charcoal water filter today for your home and find the taste difference. Purifying water with charcoal means knowing the system is great at removing unwanted slime, dirt, and eliminates everything.
