Utilizing the natural resources found on Earth, natural water filtration system is a basic method that purifies water so that it is suitable for use and consumption. The use of this technique predates the development of contemporary water treatment technology by centuries. In areas with limited access to clean water, the importance of natural water filtration cannot be emphasized. Relying on easily accessible components, these systems not only offer an environmentally beneficial water filtration solution, but they also support sustainability. Comprehending the functioning of natural water filtration is crucial to acknowledging its function in guaranteeing potable water, safeguarding public health, and preserving ecological equilibrium.
How natural water filtration works?
Natural water filtration system is a process that uses natural materials to remove impurities from water.
The most common type of natural water filtration system:
Filters such as sand, oysters, charcoal, and minerals naturally filter the earth’s water supply. A few are even effective at removing unwanted particles from drinking water.
1.Sand
Sand has been used as a natural water filter for thousands of years. Using sand to filter drinking water dates back to ancient Greek and Roman times.
These days, sand is used in under-the-sink filtration and in swimming pool filters. As the water is filtered, solid particles (such as algae) are trapped in the sand.
2.Oysters
Oysters have their own water filtration system, too! These little mollusks can filter up to 50 gallons of water a day.
The Billion Oyster Project has been cleaning up the polluted water of the New York Harbor through oyster filtration — and in turn, restoring a depleted population of oysters.
3.Charcoal – Carbon Filters
One of the most common natural water filters is activated carbon.
Activated carbon filters volatile organic compounds, pesticides, nitrates, hydrogen sulfide, metals, bacteria, and viruses through a process called adsorption.
The carbon bonds with unwanted chemicals, pulling them out of the water.
4.Reverse Osmosis
Reverse osmosis (RO) filters remove PFAS or “forever chemicals” from water as well as contaminants such as metal ions and aqueous salts.
Forever chemicals are synthetic compounds that the human body can’t break down. They seep into the water supply from landfills, factories, and industrial facilities. These chemicals may cause serious health issues that can damage reproductive organs, lungs, and other major organs.
RO forces water through a semipermeable membrane, removing these contaminants.
5.UV Filters
Ultraviolet light is another effective way to filter contaminants, such as bacteria and organisms, from drinking water.
Like other types of filtration, water is passed through the filter (in this case the UV light). The light disrupts the genetic code of bacteria and organisms, making it impossible for them to reproduce.
6.Minerals
Mother Nature has been filtering our water with minerals for thousands of years, and humans have been using minerals to filter water for centuries.
Man-made water filtration systems have been shown to remove harmful particles from drinking water; however, they may also filter minerals our bodies need and can’t make on their own, such as calcium, magnesium, sodium, potassium, zinc, and iron.
Minerals such as Maifan stone not only remove mercury, lead, calcium, and other heavy metals from water, but also add nutrients back into drinking water. Maifan stone can also neutralize the pH balance of acidic water.
Advantages over traditional water filtration methods
Advantages of natural water filtration systems over traditional water filtration methods include:
– Lower energy consumption
Natural water filtration systems require less energy to operate than traditional water filtration methods.
– Reduced waste
Traditional water filtration methods often produce large amounts of wastewater that needs to be disposed of properly. In contrast, natural water filtration systems produce little to no wastewater.
– Environmentally friendly
Natural water filtration systems are generally considered more environmentally friendly than traditional water filtration methods because they don’t rely on chemicals or other harsh materials.
– Longer lifespan
Natural water filtration systems can last for decades without needing replacement, whereas traditional water filtration methods may require frequent replacements and maintenance.
Disadvantages of natural water filtration systems
Disadvantages of natural water filtration systems include their reliance on external factors such as sunlight and rainfall, which can be unpredictable and vary in quality.
Another disadvantage is that they may not remove all contaminants from the water, particularly those that are dissolved or suspended in the water rather than present in the form of particles. Additionally, natural water filtration systems may require significant maintenance to ensure proper functioning, including regular cleaning and replacement of filter media. Finally, natural water filtration systems may not be suitable for treating water with high levels of contamination or chemicals, making them less effective than other types of water treatment methods.
Maintenance and upkeep of natural water filtration systems
Natural water filtration systems require minimal maintenance and upkeep compared to traditional artificial filtration systems.
The most important aspect of maintaining a natural water filtration system is ensuring that it remains free from debris and contaminants. This can be achieved by regularly cleaning the filter media and checking for any signs of damage or clogging.
In addition, it may be necessary to adjust the flow rate of the water through the system based on changes in water quality or usage patterns. This can typically be done by adjusting the size of the holes in the filter media or by replacing the entire filter if necessary.
Overall, natural water filtration systems are highly effective at removing impurities from water sources and require little to no maintenance once they have been properly installed and set up.
Effects of natural water filtering systems on the environment
The environmental effect of natural water filtration systems is lower than that of conventional water treatment techniques.
Natural water filtration has the benefit of not requiring energy-intensive procedures like reverse osmosis or chemical treatments, which can be resource-intensive and result in wastewater. To further lessen their impact on the environment, natural water filtration systems frequently employ recyclable or biodegradable components.
Regarding the effects of natural water filtration systems on the environment, there are a few possible disadvantages to take into account. For instance, when in use, certain filter types may leak trace amounts of iron or manganese into the environment.
Uses of natural water filtration systems
Natural water filtration systems have various applications in different industries and sectors.
-In agriculture
natural water filtration systems are used to improve soil health by increasing its ability to retain moisture and nutrients. This helps plants grow better and reduces the need for irrigation.
-In urban areas
natural water filtration systems can be used as an alternative to traditional municipal water treatment methods. They can also be used in rural areas where access to clean drinking water is limited.
-Industrial setting
include using natural water filtration systems to remove impurities from process water or coolant. This helps reduce wastewater and improves product quality.
Overall, natural water filtration systems offer a sustainable solution to improve water quality while reducing the environmental impact of traditional water treatment methods.
The following are some common misconceptions regarding natural water filtration:
Myth 1: Impurity removal from natural water filters is ineffective. Natural water filters are capable of efficiently eliminating a wide range of impurities, including viruses and bacteria, so this is untrue. In actuality, natural materials like charcoal are used in some of the world’s best water filters.
Myth 2: Chemicals and heavy metals are impossible to remove from water using natural filters. Once more, this is untrue. Even though natural water filters might not be able to completely eliminate certain pollutants or heavy metals, they can nevertheless be useful in lowering their levels in water. To lower the quantity of volatile organic compounds (VOCs) in water, for instance, activated carbon can be utilized.
Myth 3: Natural water filters require frequent maintenance. While it is true that some types of natural water filters do need more maintenance than others, many types of filters can go long periods without needing any attention. Some filters even have a lifespan of up to 50 years!
Overall, while there are certainly some myths surrounding natural water filtration, these systems can be very effective at providing clean drinking water when properly maintained and installed.
