What is the process of water filtration?

As a whole, water filtration systems are the method of reducing or removing concentrated amounts of particulate matter. That matter is comprised of algae, bacteria, fungi, parasites, suspended particles, and viruses, and other undesirable biological and chemicals from contaminated water.

Water filtration and purification’s intended purpose are to produce water that is safe and clean water for reasons like human uses such as drinking, medical, and pharmaceutical purposes. All human consumption of water runs through a water filtration process by the local water department or a water co-op. Sometimes, the water is hard and not as clean tasting as preferred. Many households will install a water filtration system in their home.

They would present a water filtration explanation as a filter or a filtrate that any fluid passes through. That filter or filtrate could be any medium that allows the fluid to flow through while it traps any solid particles. 

Filtration is usually an imperfect process as some fluid remains on the feed side of the filter are embedded into the media, allowing some small solid particulates through. As a technique within the chemistry and engineering realm, no matter what the intended collection is, there will be some lost product.

Some examples of filtration in everyday life would be:

  • Brewed coffee is the process of hot water passing through the coffee grounds and a filter. Brewed tea would be another example of this form.
  • Our kidneys are a biological filter that filters blood by the glomerulus so that our blood can reabsorb the molecules that are essential to our health.
  • The air filter in your HVAC system and your vacuum cleaner may use a HEPA filter to remove dust and pollen.
  • Many aquariums use filters that contain fibers to capture particulates.

What are the methods of filtration?

We all want our drinking water to be clean, clear, and great tasting and our local municipalities or water co-ops try to filter the water before it gets to our homes. However, it sometimes still has an odor or taste that makes it unpleasant, which is where having a water filtration system installed in our homes comes in to play.

Before you purchase a water filtration system for your home here are these three normally unknown facts:

  • Each brand of water filtration system eliminates different specific contaminants.
  • Being “NSF Certified” does not guarantee any particular contaminant is removed.
  • There is a water filtration system that rely on a single type of technology and others rely on multiple technologies.

With these 3 facts in mind, we provide you ten different water filtration system methods:

1. Activated Carbon Filtering

This method uses chemical bonding with the water to remove contaminants. Some remove only chlorine and others remove more contaminants that could be harmful like lead and mercury. This type of water filtration system does not remove arsenic, fluoride, nitrates and other inorganic pollutants.

2. Distillation Filtering

This water filtration system vaporizes water after reaching an extraordinarily high temperature.  This is the oldest water purification method that is still used today. After reaching the set temperature, the condensed vapor then becomes drinkable water after it has removed chemicals, microorganisms, and minerals. It does not volatile organic chemicals like chlorine.

3. Deionization Filtering

Deionization filters remove electrically charged ions and salts with an Ion exchange in your water. If there aren’t electrical charges in the contaminant,  they are removed with this water filtration system. These filters will not remove living organisms, such as viruses and bacteria.

4. Ion Exchange Filtering

The technology of the Ion exchange water filtration system uses a resin to supplant harmful ions with less harmful ions, typically used to soften water because it used sodium to replace calcium and magnesium. The resin requires recharging with the replacement of harmless ions in order to work for an extended period.

5. Reverse Osmosis Filtering

Reverse osmosis is a water filtration system that performs by transferring water via a semi-permeable membrane, stopping harmful and larger molecules from entering. It does not remove larger contaminants like chlorine and other large molecules with this process but removes carbon and other contaminants.  

6. Mechanical Filtering

This type of water filtration system cannot remove chemical contaminants but can remove cysts and sediments through small holes. It is often paired with another filtration technology.

7. Ozone Filtering

Ozone is another water filtration system that is used with another technology to effectually kill large numbers of microorganisms but cannot remove chemicals.

8. Carbon Block Filtering

Crushed carbon particles are the substance that carbon block filters are made from, and because they have a bigger surface area, they are more effective than other carbon-based filter types. They base the effectiveness of this water filtration system on the water flow rate.

9. Granulated Carbon Filtering

This water filtration system uses small grains of carbon and is less slightly less effective than the block-shaped filter described above. The speed of the water flow influences its effectiveness.

10. Water Softeners Filtering

Water softeners are a water filtration system that uses Ion exchange technology in order to reduce the amount of calcium and magnesium in the water. If the plumbing in your house has a history of accumulating mineral buildup, this is the perfect filter.

Is water filtration necessary?

By the time water has reached your home, it has been filtered. However, an additional water filtration system will improve the taste of the water by removing chlorine and other chemicals, and pesticide residues.

Are water filters a waste of money?

Tap water isn’t as refreshing as you might think, and your nose and taste buds will confirm this for you. Even after your water municipality has filtered the water, there are often potentially harmful elements that come from your pipes. Installing a water filtration system can be beneficial as they can remove as much as 2,100 contaminants.

Which water filter pitcher removes the most contaminants?

ZeroWater is the pitcher that provides water filtration is the best job at removing all the contaminants. It is NSF certified by Standard 53 in reducing chromium-6, lead, and mercury, and is a reasonably priced water filtration system for the home.

If you find yourself in need of a water filtration emergency, and there is not any bottled water, a thorough boiling will kill any pathogenic bacteria, protozoa, and viruses.  Thoroughly boiled water is water that has boiled for three minutes and allowed to cool naturally. If there is a flat taste to the water, adding one pinch of salt to a liter or a quart will remedy that. Water filtration can give you quality water for your home.
