Since limestone is a porous rock, it can trap the contaminants in dirty water in its pores, meaning that only purified water can filter down through its layers.
This makes limestone an excellent natural water filter.
If you are completely new to the concept of limestone water filters, or you have no idea how to use it or how it functions, you’ve come to the right place.
This article will lay out all things limestone water filters in crystal clarity.
How Does Limestone Filter Water? (EXPLAINED)
What exactly is limestone?
Limestone is a rock comprised mainly of calcium carbonate (chemical structure: CaCO3).
This is a mineral called calcite. It typically forms in calm, clear, warm, shallow oceans.
Limestone is usually a sedimentary rock, meaning that it is formed by an accumulation of layers.
These layers are the shells, coral, algae, feces, and other organic waste in limestone.
However, limestone can also be formed by chemical processes that cause sedimentary (layer-by-layer) formation.
For instance, it can be formed by the precipitation of calcium carbonate out of ocean or lake water.
Humans have used limestone as a water filter for thousands of years
It’s a natural mineral that mankind has employed to cleanse water over thousands of years.
The most important thing is to ensure that the limestone is pure and free of pollutants or impurities.
Limestone is a mineral that occurs naturally, making it ideal for use in purifying water.
Limestone as a water filter is definitely a healthy alternative since it doesn’t use chlorine or chloramine.
In fact, limestone is often employed to purify water when there aren’t other alternatives, since calcium and magnesium particles can take out various things from water.
Limestone is a great way to remove contaminants and chemicals that could cause harm to health, like copper or lead.
It also helps eliminate bacteria that can cause illness for humans when consumed.
Modern limestone filtering devices
A limestone water filter is an instrument for filtering water that uses the natural characteristics of limestone and rocks.
It acts by filtering water over a long period. However, it doesn’t eliminate any parasites or bacteria in drinking water.
Many people think that limestone actively cleans water, but in fact, it simply traps contaminants.
How come limestone can filter water?
Limestone can filter water due to its porosity.
Limestone is a porous rock that absorbs numerous contaminants, including chloramines.
The ability of limestone to remove water pollutants makes it a powerful instrument for eliminating heavy metals as well as other particles in drinking water.
A limestone water treatment plant in Finland has successfully reduced the amount of ammonia present in the drinking water to just 20%.
At yet another Finnish water treatment plant, technicians increased the alkalization water (a good thing, since acidic water rots teeth and causes other problems).
When water becomes sufficiently alkaline by passing through an exchange filter, it ends up being much gentler on your skin and in your stomach.
Also, limestone filtration can increase the calcium content in water, which scientists say has a beneficial health effect on those who drink such water.
The limestone water filter works through a process known as “absorption”
Limestone is a powerful filtering method since it filters water using a process known as “absorption”.
To deal with germs and bacteria, though, it is important to remember that this limestone filtration requires the use of UV (ultraviolet) light for disinfection of the filtered water to occur.
The same porosity of limestone, which helps clean the water, is the vital characteristic of limestone that allows bacteria, viruses, microorganisms, and protozoa to get through.
Limestone filters use activated carbon to help remove organic matter from water in the filter.
Activated carbon helps eliminate chlorine, bacteria, and chloramine and traps heavy metals like lead and mercury.
So, by combining limestone with activated charcoal in a limestone water filter, since there aren’t any moving parts, patrons get an ideal solution for purified drinking water without the need to keep buying expensive replacement bits and pieces.
How good is limestone as a naturally occurring water filter?
Although limestone isn’t always the most effective water filter, it still has its advantages.
It’s a great option to consider when you reside in an area with large amounts of impurities or minerals in water, contaminants that need to be removed.
So, piped water that has passed through limestone is typically safe to drink as (in the absence of other contaminants) limestone cleans the water, removing debris and metals from the source water.
To make sure that drinking water is completely safe, it is necessary to thoroughly boil the water first for at least ten minutes.
Pour the water into the limestone filter after allowing the water to cool down.
This will prevent illnesses like cholera and typhoid because boiling destroys these germs.
How safe is it to use limestone as a water filter?
Limestone is an organic rock (meaning that it came from once-living things) that is abundant throughout the globe.
It has been exploited for centuries as a reliable way of filtering water as well as cleaning it.
Limestone doesn’t affect the flavor or color of the water.
As discussed above, however, limestone enhances the alkalization of water.
Researchers have discovered that limestone is a natural alkalizing ingredient in water treatment techniques.
It is efficient in eliminating certain microbes from the water supply.
Limestone can also be utilized to provide an additional dose of alkalinity through the supply of carbon dioxide.
It increases the value of water and also improves the quality of water in a variety of ways.
Limestone changes the water’s pH, making sure it’s safe for household and other uses. It assists in softening water as well as water purification and pH coagulation.
In short, limestone affects the quality of water positively.
The price of water filtered with limestone is lower than tap water, making it suitable for everyday life.
Is there a limestone water filter for household use?
Actually, there are several limestone water filters specifically designed for household use.
Some of these limestone water filters are perfect for people looking for easy and fast installation procedures.
A careful search on the Internet will reveal great alternatives with really good reviews from buyers who have previously bought and enjoyed their product.
Look for filters that do not require experts’ assistance to install or clean. Also, favor those devices equipped with an environmentally friendly copperhead.
Conclusion
Limestone isn’t necessarily the most effective filtering medium, but it can be extremely efficient in certain locations.
The thicker the limestone and its purity, i.e., the absence of oxides, calcium dissolved impurities in the limestone, and the greater depth the unfiltered water will have to penetrate into the aquifer collecting area, the more effective the purification effects will be.
