Activated Carbon Filtration

This filtration process is the most common type of filtration that employs the use of relatively inexpensive carbon filters. In this filtration system, activated carbon attracts and absorbs particles in water as the water runs through a filtering screen impregnated with carbon. This filtration process removes heavy metals, chemicals, parasites, radon, pesticides, and MTBE if present in the water. Activated carbon filters are commonly used in point-of-use devices such as pitchers and under-sink or faucet-mounted units.wholesale activated carbon


Activated carbon filtration can also be found in some Shower Head Filter systems. The combined use of activated carbon with other stages can enhance the quality of the water you are showering with for a better overall feel on your skin and hair.


Reverse Osmosis

This filtration process is one of the most effective water filtration systems and is typically employed in point-of-use devices. Reverse osmosis, however, may be more expensive than some other filtration systems. In this filtration system, pressure forces water through a semi-permeable membrane that removes practically all contaminants.


Although this filtration method eliminates more pathogens and chemicals than other methods, its downsides remain cost and water wastage. For example, for every 3.7 liters (1 gallon) of filtered water produced, about 15 liters of water (4 gallons) will get thrown out. If you have a compromised immune system or want the cleanest water for consumption, this filtration method remains the best option.


Aeration Filtration

This filtration process forces water into the homes as high-pressure air jets. Therefore, contaminants that quickly become gases, e.g., fuel byproducts or radon, will evaporate. However, other contaminants like heavy metals (e.g., mercury) and parasites may remain in the water. This type of filtration system may be employed at the point of entry systems and for water samples that are known to have the concentration of heavy metals and pesticides within the acceptable range.


Cation exchange

This filtration process attracts and traps positively charged ions such as magnesium, calcium, and barium by the use of negatively charged particles within the exchange resin. As the water passes over the beads in the exchange resin, the particles responsible for the hardness of water (calcium and magnesium) are trapped. Consequently, the water becomes "soft". Calcium and magnesium do not have health risks, but they can damage pipes in the home. Barium, however, can be a health concern.activated carbon pellets for air filter

The charcoal absorbs impurities in water and is actually one of the only ways of removing chemicals from water, such as pesticides and runoff.activated carbon for pharmacy


These instructions for a DIY charcoal water filter are very easy. Yet, it is essentially the same process used in city water treatment facilities (just on a smaller scale).


1. Get activated charcoal

You cannot use barbecue charcoal to make a water filter, the reason being that most charcoal you buy at stores is not pure and could leach numerous chemical contaminants into the water (which defeats the point of making a charcoal water filter). Instead, you will want to make activated charcoal.


In a wilderness survival situation, you could make your own basic activated charcoal out of hardwood.After making activated charcoal, you will need to crush it into a powder.Alternatively, you can buy activated charcoal. It is available in bulk on Amazon at a decent price.


2. Rinse your activated charcoal

Before using activated charcoal for filtering water, you should rinse it to remove any impurities on the surface. Then spread it on paper and let it dry. This is the same reason you need to soak a Brita filter before using it and the step is even recommended by NASA.


3. Create your filter vessel

Most survival charcoal water filters are made from 2-liter plastic bottles.If you don’t have a bottle handy, you can use cloth to hold each filter layer (see pictures in section below).Or, if you are very skilled at bushcraft, you can make a cone out of birch bark.


4. Gather pre-filter materials

It is possible to make the filter out of just charcoal. However, any debris, algae, or other scum in the water can clog the top layer of charcoal. For this reason, it’s recommended that you make a layered filter.


Usually gravel and sand are used as pre-filter media. However, I’ve heard of people using things like cotton balls, pieces of concrete, and even uncooked macaroni.


5. Pour water into the filter

Pour water into the top layer of the filter. This is technically a “gravity filter” as you have to wait for the water to work its way through each of the layers. Yes, it will take a while!https://www.coconutactivatedcarbon.com 

Carbon filtration works through a process called adsorption. A bed of activated carbon attracts unnecessary water contaminants and impurities, like chlorine, VOCs, and more, improving the taste and smell of the water.activated carbon pellets bulk


Adsorption is essentially similar toabsorption, except the material or compound or liquid adheres to the surface of the medium, and not inside of it. Instead of a sponge soaking up water, think of adsorption like a window in the winter, attracting warm water molecules to its surface.


When it comes to water filtering, this adsorption process makes medium renewal easier. Think about wiping a dirty window off with a rag. It’s much easier than trying tocompletelysqueeze a sponge dry of any liquid at all. If you choose a carbon water filter, the process of adsorption guarantees that your medium, whether granulated or block carbon, will last that much longer. That means a more effective filter for less money.


However, not all compounds and contaminants are removed by carbon filtration. For the compounds that aren’t filtered by carbon, opt for a system that comes with a sediment pre-filter. The benefits are two-fold: 1. Thicker, bigger sediment is filtered more effectively, and 2. Since that same sediment never reaches the carbon media, the carbon media’s lifespan will be much longer. Even though it might mean a greater up-front cost, it will result in significant savings over time.


Finally, focusing this closely on carbon filtration is important because your body is 60% water. Water is literally the #1 substance you will voluntarily consume over your lifetime (as opposed to air, which happens automatically). Therefore, it deserves a significant investment of your time and energy


And, when it comes to the best carbon filtration out there, coconut-shell-activated carbon is the industry leader. It’s more easily renewable than any other type of carbon.


Generally, there are two types of carbon water filters:


Granular activated carbon

Carbon blocks


Of the two, carbon blocks have a higher contaminant removal ratio. Solid block activated carbon has been grounded into a mesh that´s anywhere from 7 to 9 times greater than granular activated carbon. However, it might slow down your flow rate.


So, even though carbon blocks technically have a greater surface area than granular activated carbon, that doesn´t mean that granular activated carbon can´t also get the job done, especially if it´s coconut shell activated. Coconut shell activated carbons are the most renewable, and that´s why they´re the industry leading standard.www.yrdcarbon.com
