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
