How to Remove Calcium from Water! Problems Due to The Presence of Calcium in Water
“Too much of anything is not healthy,” goes the old saying. Ironically, that also includes water. Water without minerals is hardly complete (in terms of nutritional advantage).
However, water that is over-saturated with mineral deposits can be hazardous to your skin, health, and your home. Ultimately, the cons outweigh the pros if the water is hard. Hence, the removal of hardness from water becomes necessary.
Hard water describes any water that has a very high concentration of mineral content. The mineral content contained in hard water is usually formed from water penetrating through the mineral deposits of chalk and limestone. Hard water would naturally contain high percentages of magnesium and calcium carbonates that make it hard. Suds formation will take longer to develop when you distress soap inside hard water – its a stress-free way to tell that the water is hard.
How Do You Know When Water is Hard?
Several signs can help you determine whether water is hard or not. For example, when hard water evaporates, it leaves some residue of calcium and some other minerals that will not evaporate alongside. Some other quick-fire indications you will find at home include the following:
- Rusty stains on kitchen appliances like sink, water tap, around the drainage, etc.
- Limescale reactions from mineral deposits on bathroom plumbings.
- Dryness of the hair.
- Hair fall.
- Hair removal.
- Extreme dullness of skin color and texture.
- The lack of shine on clothes when you use hard water to wash, etc.
If you notice these signs in your home or on your body, it means you’re using hard water. To make your water supply more suitable (both for household and body use), the first step is to check the level of hardness of the water. You can easily measure water hardness using a TDS meter.
Some other popular indicators of hard water include the presence of Limescale.
What is Limescale?
Defining it merely, Limescale is the chalky, white residue left behind from the activity of magnesium, calcium, and other dissolved minerals present in the water. Usually, it forms a hard white crust around the mouth of your bathroom or kitchen taps. The hard coating can prove very tough to get rid of after it has developed.
You can also find Limescale on your kettle, water glasses, coffee maker, cooking pot, frying pan, cutleries, and so on. Statistics show that up to 86% percent of homes in the U.S.A. and over 84% of European houses are plagued by.
Is it Bad to Have Limescale in Tap Water?
The major constituents of Limescale in tap water are magnesium and calcium. Contrary to what most people believe, these minerals are not considered to be unhealthy for the body. Limescale, in a reasonable amount, contained in tap water, does not inflict any harmful effects in your system.
Minerals like calcium and magnesium are healthy for the body when consumed moderately. The recommended daily consumption of calcium for the body is between 500 to 1200 milligrams. Magnesium’s daily recommended intake is 300 milligrams.
You can get ten to twenty percent of your body’s recommended daily requirements of calcium if you take up to two liters of water daily. Also, tap water can provide your body with up to one-third of its required magnesium.
What Makes Water Soft?
Ultimately, when water is in its most natural state, like rain or water in the ocean, it is soft. However, as water flows through high mineral materials under the ground, through rocks, etc. it collects some portions of the mineral-materials. Some of the common minerals found in hard water formed like this include magnesium and calcium deposits.
You can measure water hardness by the volume of the mineral-deposits contained in the water. Soft water will have a calcium concentration of fewer than seventeen milligrams per liter.
If the water contains between seventeen to sixty milligrams of calcium per liter, you can consider it to be slightly hard. If it contains holds between sixty to hundred-and-twenty milligrams of calcium per liter, then, it is found moderately hard. Meanwhile, if the calcium content is around hundred-and-twenty milligrams and more, per liter, it is considered to be very hard.
What About Hard Tap Water?
Water is considered hard because of the presence of mineral content in it. Minerals are essential for the body as they enrich the body with necessary minerals that have nutritional benefits. Some of these minerals include magnesium and calcium; they are mostly harmless to the body.
The intake of hard water (including very hard water) can provide supplementary assistance to your body’s total magnesium and calcium consumption.
Some research in epidemiological studies has shown some evidence that hardness from magnesium has protective effects against cardiovascular mortality. However, there are a couple of health conditions, including kidney stone cases, where doctors advise patients to abstain from hard water. Ultimately, the studies are currently inconclusive.
How to Remove Calcium From Water
There is a lineup of numerous techniques to reduce or get rid of calcium from hard water. Some of the best practices include:
- Using conventional water softeners
- Ion exchange
- Reverse osmosis
- Combine scale removal filters
- Scale inhibition filters
- Use of magnetic, Ionization, and catalytic devices, etc.
Using Conventional Water Softeners
This method helps to remove the magnesium and calcium and then substitutes it with sodium instead. This intervention is excellent for preventing limescale build-up in the water. However, its methods are not entirely health-friendly.
In this method, we reduce water hardness by using cation resins. The cations used are usually resins that have strong-cation / strong-acid (SAC) resin beads. The process also helps to increase the concentration of sodium in the water. Scale-forming magnesium (Mg2+) and calcium (Ca2+) ions even are exterminated in the process.
Like any other solution, ion exchange also has its tiny perks. The process can modify the water by increasing its acidic levels to a notable extent. The changes, particularly with the taste, could take a couple of weeks to become accustomed to, mainly if your body is already used to consuming hard water.
On the bright side, however, the ion exchange process leaves you with water that is excellent for making delicious cups of coffee and tea. High-street coffee stores often patronize this kind of water to make their hot beverages.
This method employs the use of membranes to reduce water hardness. The membrane used usually consists of very tiny holes. It pushes out the “pure” water while blocking hard water ions such as lead, magnesium, calcium, and so on.
Afterward, the purified water is channeled through the membrane’s filter leaving behind hard water ions like magnesium, calcium, etc.
A notable advantage for this method is the fact that it doesn’t replace the former ions with new ones like in most other techniques.
Meanwhile, the drawback would be the expensive cost of maintaining reverse osmosis machines. If the devices are not adequately supported, they begin to lose their effect.
Filtering and Purifying Drinking Water
It is essential to filter and purify drinking water before drinking. Purification can help to reduce water hardness in drinking water. There are various ways through which you can purify water for Drinking. Some of the best practices include:
- Using a reverse osmosis water purifier
- Using a water filter
Installing and Using a Reverse Osmosis Water Purifier to Purify Water
You can buy a reverse osmosis water purifier attachment and install it on your kitchen faucet. Alternatively, you can install it under the kitchen sink.
The machines may vary in design and application, one from another. However, they all offer similar results. You can follow the manufacturer’s guidelines to install and learn to use them properly.
Ultimately, the reverse osmosis water purifier will help to magnesium, calcium, and other hard water ions from the hard water. A water faucet attachment offers a ready solution for getting rid of calcium and purifying water for Drinking.
Boiling Drinking Water to Make It Soft enough for Drinking
Boiling is the most common and most basic method for purifying drinking water. The process is also quite simple.
- Boil the quantity of water you need
- The water should continue to boil for at least ten to fifteen minutes
- Allow the water to cool afterward before drinking
When you boil water, you also remove some of the mineral deposits that make it hard. Some calcium mineral deposits, like carbonate hardness (which constitute water hardness), are easily gotten rid of in the process. However, it doesn’t eliminate everything.
The carbonate hardness that can be gotten rid of by boiling includes calcium hydroxide, calcium bicarbonate, and calcium carbonate.
Use A Water Filter to Improve the Taste of Drinking Water
Home carbon water filters are excellent for improving the taste of drinking water. While this equipment doesn’t wholly remove calcium, it can get rid of other chemicals, including chlorine. But, most importantly, they are designed to improve the taste of drinking water altogether.
Installing Water Softeners
Water softeners offer similar effects as chemical treatment. Also, they do not add any other additional substances to your water supply. The device substitutes magnesium and calcium to replace them with sodium. This substitution helps to alter the water structure for Drinking.
When the substitution takes place, the device will filter calcium along with other impurities of hard water, leaving you with a cleaner and more drinkable water.
Why is calcium present in water?
Calcium is naturally seen in the water. This may dissolve rocks like limestone, calcite, marble, gypsum, dolomite, apatite and fluorite.
Calcium is a precondition of water hardness as this is found in water as Ca2+ ions. Magnesium is considered as the different hardness.
Calcium can be seen in may construction materials, like cement, concrete and brick lime. This is also present in batteries and is used in plaster like calcium sulfate. The metal is used for thorium and zirconium production.
Calcium is used as blotter in the steal industries, is added to aluminum, lead alloys and copper. Calcium can be extracted sulfur dioxide from the industrial exhaust, or neutralize sulphuric acids prior discharge.
The another use of calcium is calcium hypo chloride for bleach for disinfection, porcelain industries or calcium phosphate, hydroxide, calcium polysulphide, as flocculants in wastewater treatment, calcium fluoride as turbidity agent in the enamel industries, and in UV spectroscopy and raw materials for fluid acid production.
Calcium may be used as removal of sulfur or carbon and iron alloys and iron, for dewatering oil. Limestone is used as paper filler may cause the paper to color whither and in plastics to improve stability.
Calcium sometimes affects the quality of the soil, and different compounds are used in fertilizer. Suppose, CaCl2- or Ca(NO)3 are used in horticulture. Again, Calcium oxide is considered dehydrating molluscicide.
Health impact of Calcium Water?
There are lots of other factors that affect the amount of Calcium in the body what we take at the time of eating and drinking. We get sugar in the milk, lactose aid the body absorb from what we eat or drink.
At the time of taking vitamin A and D, we should consume moderate amount of fat to develop the absorption rates. Milk and other skim milk will give more fat to absorb these vitamins.
So milk is the best source of calcium as it is fortified with vitamin D and A. A glass of eight-ounce milk contains 300 milligrams of 1000 milligrams of calcium suggest for the people whose age is from 19 to 50.
For the age 9 to 18, the requirement goes up to 1300 milligrams for a day as the body is growing very fast.
There is calcium in hard water but less than milk, eighty or 120 milligrams of Ca per liter of water. You should not give up milk unless you are eating a significant amount of calcium rich foods.
Drinking hard water may contribute some portion of calcium on a diet.
The hardness of water varies from community to community; you will get the best amount of calcium from the tap water of the local water treatment or delivery authorities.
When you do that, you may select whether you desire to Mike the hard water for its worth.

Pros and Cons
Hard water has its health benefits and does not quite pose any health threats. However, the magnesium, calcium, and other mineral constituents of hard water can produce alongside other characteristics that are not very pleasant. There is a lineup of ways through which you can get rid of hardness from water and make it more enjoyable for Drinking.
However, non-chemical softening methods merely condition the water and does not weaken it. Meanwhile, chemical methods ensure that the hard water is altered on a molecular level. This alteration helps to exterminate hard water mineral ions to make it soft as well as more pleasant for Drinking.
