What is the difference between distilled water and rainwater

If I tell them that I usually make tea with rainwater, they will frown at me. To be honest, it is true that rainwater is acid. The acidity of clean water is 5. If the region it rains on has the source of the air pollution, the acidity would be stronger so the level of pH will be pH The acidity is stronger as the value of pH gets lower. However, after another 20 minutes of rain, the acidity becomes far weaker than before.

Some impatient people will tell me again that it is true that rainwater is acid. However, they will change their thoughts after they hear about how less dangerous the acidity of rainwater is compared to other things. The acidity of liquids we encounter everyday is far higher than rainwater. The acidity of Cola, a typical carbonated drink, is 2. Then, you might argue that the acidity difference between these items and rainwater is just pH.

In this point, however, although the numerical difference is small, the acidity difference is in fact huge. No parents worry about the acidity in the juice and yogurt their kids drink every day. Then why are we afraid of rain, whose acidity is far weaker than that of beverage? The answer is our lack of knowledge. Rainwater Research Center in Seoul National University investigated how much the acidity of rainwater is dangerous.

We measured the pH of rainwater from a gutter of the roof. Then, during the short period of time while rainwater passes through the roof, its pH changed into This figure is not related to our health and thus rainwater is safer than juice, yogurt, a shampoo and a conditioner. An experiment has shown that washing hair with rainwater is good for our hair and there is no problem with the acidity of rainwater. After days, we measured the pH of rainwater again, and it was already neutralized! We can save water costs by cleaning a room and watering the flowers with this gathered water.

If you are still concerned about this, boiling the water is another way. It has rained everywhere from the past, but why do especially Koreans have an aversion to acid rain, which was not a problem in the past and in other countries? When I went to Tokyo to attend the International Rainwater Forum, Japanese housewives were treating guests with tea made up of rainwater. Someone introduced a device that operates a portable water purifier using a hand pump or a pedal so that they can filter out rainwater without electricity in emergency.

In this way, many countries including Japan use rainwater universally in everyday life. Among them, Germany, who is one of the developed countries, uses rainwater in many fields in their daily life.

I hope you do not consider acid rain seriously anymore. If there is a problem, we can deal with it wisely. So rainwater is not a disaster, but a gift and a blessing from the sky. If there is someone who thinks they became bald because of acid rain, how about raising funds that offer medical expenses and compensation? But if they want to be covered by this fund, they should prove an obvious and scientific causal relationship between baldhead and acid rain.

Now you do not need to run in the rain. I will give you a wig as a gift that is completely strong enough for acid rain. If the queen from the Snow White story were born these days, she would also have doubts about water.

For this woman who has so many worries about safety, which water will be the best? Expensive bottled water from abroad? Or, water from a mountain valley? Or, natural aquifer under the ground advertised in a beer commercial on TV?

Among them, if the safest water is proved scientifically, the queen will try to get it at any cost. However, what is the possible way of getting water for ordinary people?

I will explain how safe and clean rainwater is with a scientific story. This is an indicator indicating the amount of foreign substance dissolved in water. It is a somewhat difficult term, but this is the amount of remaining sludge in 1 milligram after 1L of filtered water has evaporated. Suppose that we have water, a cup, and sugar here. After evaporation, the amount of sugar would be 0. Then, I want to talk about the TDS and safeness of various kinds of water that we can see around us.

When we boil groundwater from the European region, limestone is left. It is hard for Koreans to understand this situation. How could Europeans drink water containing limestone? However, Europeans are very healthy and drink water without any doubts. Why is that? Water bottles have labels indicating a TDS figure. TDS of bottled water from the Alps is more than ppm. However, that of bottled water in Korea is only 30ppm. Korea is famous for clean water and good mountains.

It is rare to find a country whose water is as clean as that of Korea. When your container is as full as you want it, leave it to stand outside for two days. This will allow the minerals to dissipate and leave you with pure water. After two days, pour the distilled rainwater into one or more clean jugs and store as appropriate. If you plan on drinking your collected rainwater, there are three effective ways to ensure clean H2O. These include:. For short-term use of drinkable rainwater, boiling is the best option.

Boiling the water will kill viruses, bacteria, and parasites. The CDC advises that you boil the water for one minute, then allow it to cool before storing it. Your drinking water should be stored in a clean container with a cover.

There are many types of water filters available, and all vary in effectiveness against different contaminants. Some of the more common filters include ceramic, carbon, and membrane.

The most effective filter to remove pathogens is one with a pore size of less than 1 micron 6. Most commercial purification products use either iodine or chlorine. Iodine tends to be more effective than chlorine.

However, even though iodine is a necessity in our diet, overconsumption can lead to thyroid problems. To combat this, use a carbon filter to remove excess iodine after the treatment.

Distillation kits use electricity to run, which will show up on your bill. However, you still have to pay for the treatment and items necessary. Many experienced distillers have found it to be more expensive to make than to buy. Distilled water is the purest water you can find. Fluoride is often added to our groundwater in its unnatural form of either sodium fluoride, sodium fluorosilicate or fluorosilicic acid.

Although some water filters will remove a great amount of fluoride, most will only reduce it. Distillation, on the other hand, will remove all fluoride — leaving you with pure and healthy water to drink. Distilled water used in cars, appliances, and for other uses can be stored for over a year in the right conditions. You should also keep it far away from direct sunlight. As a result, the fridge is a perfect choice. One thing that could ruin your distilled water is storing it in a dirty bottle or container.

This could introduce new bacteria or contaminants to your pure H2O. The best way to ensure a clean container is to disinfect it using a natural product such as white vinegar. To make it even cleaner, you could use distilled white vinegar. It's confusing. Tap water is the easy one. Turn on your kitchen faucet. Tap water. The quality of tap water varies by location, and might contain traces of minerals specific to the geology of your region, as well as traces of chemicals used on municipal water treatment.

Hopefully your tap water is safe to drink, but over 45 million Americans don't have that luxury. Filtered water is one solution. Filtered water starts out as plain tap water. You may already have filtered water in your home by way of a whole house filtration system, a faucet filter or a water filtration pitcher you can even get a filtered water bottle.

Most filtered water passes through some combination of carbon and micron filters, which help to remove chemicals such as chlorine commonly added to municipal tap water as a disinfectant or pesticides, and metals like copper or lead. Filters can also eliminate foul odors and tastes. Purified water usually begins as tap water as well. It will go through many purification processes, including those used for water filtration.

Purified water goes a step further than filtering, with a process that removes chemical pollutants, bacteria, fungi, and algae. You'll often find purified water in bottles at your local grocery. Distilled water is a more specialized type of purified water, but much easier and cheaper to produce at home. As with purified water, it meets the classification requirement of 10ppm parts per million of total dissolved solids, aka, contaminants or less. The process of distilling is simple. Heat tap water to the point that it turns to vapor.

When the vapor condenses back to water, it leaves behind any mineral residue. If we had no air pollution, we would have far less pollution in our drinking water. Rainwater collection is gaining popularity.

Rainwater can be collected in large tanks underground or in above ground barrels. The prices and size of the collection systems vary. It is beneficial to collect rainwater because it reduces the demand on our existing water supply. Rainwater can be used for nearly any purpose and it can be tied into an Aquasana whole house filter with a UV filter to kill any bacteria.

Hard water is formed when water runs off through deposits of limestone and chalk which are largely made up of calcium and magnesium carbonates. It is saturated with calcium, iron, magnesium, and many other inorganic minerals. All water in lakes, rivers, on the ground, in deep wells, is classified as hard water.

Soft Water is water that is soft in comparison with water which is harder. Soft water is surface water that contains low concentrations of ions and in particular, is low in ions of calcium and magnesium. Soft water naturally occurs where rainfall and the drainage basin of rivers are formed of hard, impervious and calcium poor rocks. It may contain many trace minerals and chemicals, viruses and bacteria.

The term may also be used to describe water that has been treated by a water softening process. Because soft water has few calcium ions, there is no inhibition of the action of soaps and no soap scum is formed in normal washing. Similarly, soft water produces no calcium deposits in water heating systems. R everse osmosis RO is a water filtration technology that uses a semipermeable membrane to remove larger particles from drinking water.

Anything smaller than a water particle passes through the RO membrane. Anything larger, like dissolved solids, gets trapped to separate impurities from our drinking water. One of the problems with this filtration process is healthy minerals like calcium, potassium and magnesium also get trapped in the membrane.
