What is distilled water? This question will be answered in the following. Other question “what’s difference between distilled water and filtered water” will be also answered.
If the water is completely pure and doesn’t contain any other substance, it can be defined distilled water. Distilled water is regarded as the purest water in the world. How to make distilled water? Water is heated to boil and the steam is condensed into liquid water again. This process is known as distillation. And the result water is distilled water. During the distillation process, most of the impurities don’t exist, because they are left in the boiler.
Information about Distilled Water
When rainwater is formed at the first, it almost can be called distilled water. Because it will reacted with CO2 as well other pollutants, the acidity of rainwater increases. The sulfur and nitrous oxides are converted into sulfuric and nitric acid accordingly. Therefore, when rainwater drops and reaches the ground, a yellowish tinge is attained.
What is the pH of Distilled Water?
First, we should know what the PH is. We use PH to measure the acidity or alkalinity of a particular solution. This words comes from two words. The letter P stands for a German Word ‘potenz’ which means power in English, while the letter H stands for hydrogen. Therefore, its original meaning of pH is the “hydrogen power of a solution”. The pH of pure water needs to be 7, indicating that the liquid is neutral, neither alkaline nor acidic. Of course, if the distilled water doesn’t contain any other impurity, the pH should be 7. However, in our daily life, or in laboratories, it is difficult to get pure distilled water and the pH should be 5.5 to 5.8. This is because distilled water is prone to interact with CO2 in the air, making it a little acidic.
Distilled water Vs Purified Water
Purified water is prepared by using a water purifier to filter water, while distilled water is prepared by boiling it and condensing the stream. Therefore, purified water contains some impurities more or less, while distilled water doesn’t contain any solid substance. Demount of impurities can be removed by a water filter depends on the filtering ability of a water filtration system.
What is Distilled Water Used For?
Distilled water is not only useful in laboratories, but can serve more purpose than you think.
Conducting experiments and Cleaning lab ware
Distilled water is ideal for conducting experiments and cleaning lab wares. It is one of the most important purposes.
Drinking and Cooking
If you use a home water distiller to get distilled water, of course, distilled water is suitable for drinking and cooking. For example, you can use it to make a cup of coffee and don’t need to worry about the impure tap water will ruin your coffee. The coffee flavor can be kept well. If you are on a low sodium diet, distilled water is your best choice.
Developing photographic films
Although you don’t use a film camera to take pictures, in the industrial or medical areas, distilled water is perfect for developing photographic films. This is because there is a layer of certain chemicals on the films. If distilled water is used to developing them, all the chemicals will be washed away.
Filling wet-car batteries
Distilled water is so pure, making it perfect for filling wet-car batteries.

If you ask me which household appliance is essential to my family, I would like to tell you that it is a reverse osmosis system which I use to get filtered water to drink, cook and wash. We cannot live without water and our body contains too much water. How to drink water healthily is very important. A reverse osmosis system is a water treatment device which we can use to purify water. Compared with other water treatment devices, RO water filter can provide us with plenty of pure and healthy water to drink and cook.
I hate tap water due to its bad smell and taste; I didn’t enough water every day before, even if I knew that drinking 64oz water at least per day is essential. After buying my best reverse osmosis system, everything has been changed. I have enough filtered water to drink and cook, as well as my wife and kids. I also don’t buy bottled water because the filtered water smells and tastes very well.
You may think there are so many types of water treatment devices and why do you need to purchase a RO system. This is because reverse osmosis is the most economic and effective way to purify water. Other types of filters, like water pitcher filters, active carbon water filters, water distillers, or refrigerator filters, aren’t able to effectively remove most main contaminants in our tap water.
The reason I don’t drink bottled water is that RO filtered water is considered as the safest and most healthy water for drinking. Now I like to drink water and I can’t live with my best RO system.
Why do you need a reverse osmosis system?
Our tap water contains many contaminants and our RO systems can remove them effectively.
RO filtered water tastes and smells great as well as bottled water and we don’t need to buy bottled water because we don’t know what’s in the bottled water.
RO water can make our drinks or food not contaminated and tastes better. For example, we can use RO water to cook tea/coffee or make juice for a better taste.
RO water is also perfect for some appliances which need to use water, like irons or humidifiers. RO water can protect them and make them work more effective.
Our pets or plans may also need RO water because of its purity.

On the market, there are many RO system manufactures and all boasts that their RO systems are the best in the world – fastest, most effective, easy to install and maintain, and stress free. However, once you have bought their filters, you will find some their products don’t seem as good as they describe. I don’t say all of them don’t keep their words and some of these manufacturers promise and do provide the best products. If you decide to make an investment, you need to know these top brands of RO system. When you choose a water filter, choosing the right brand is a half success. In the following, we will discuss some of these top rated brands.
You may hear of Home Master, if you have known something about RO systems. Home Master is really a top rated brand. Home Master RO systems always use the latest innovative water treatment technologies and can produce pure water. Generally, these systems have up to 7 stages of water filtration and can get rid of up to 98% of harmful chemicals in our water. To improve the taste of RO water, they also add calcium and magnesium minerals back. Therefore, you don’t need to worry about the lack of healthy minerals in the filtered water. Plus, their filters are high quality and can provide you with about 2,000 gallons of water without replacing new filters.
In their systems, larger fittings and tubing are used to make the water flow rate doubled, which is unlike other traditional systems. Other traditional Reverse osmosis under sink water filters doesn’t have so many stages as others and only produce highly pure water without any minerals, making the filtered water taste a little acidic. Actually, the demineralized water is not good to consume. However, Home Master systems re-mineralize the RO water and make it much healthier and have a better taste.
All their RO filters use carbon pre-filters that are made up with catalytic carbon filtration media, so the very persistent chemical contaminants can be effectively removed. What’s more, Home Master systems don’t have the canister filtering housing problems that other traditional systems have. Traditional Ro systems only allow the filters to be changed when the canister housing remains intact, thus biofilm, sediments as well as microorganisms accumulate and weaken the canisters finally. If this happens, leakage or even machine failure will happen. However, Home Master systems don’t allow this to happen. With its “all in one” modular design, the entire filter housing allows to be removed entirely without any leaks.

Generally, a basic RO system contains 3 stages of filters – a pre-filter, a semi-membrane (the key filter) as well as a post filter. The process is as the following: At the beginning, sand, dirt, silt as well as chlorine will be removed by the pre-filter. This process is also helpful to protect the membrane. Then the semi-membrane will only allow water to pass through but other contaminants (like heavy metals, chemicals and other contaminants) will be left on the other side of the membrane. This is the core process of a RO system and this process remove main contaminants in our water, making it distinguish from other different types of water filters. The waste water that contains separated contaminants will be Discharged to the sewer, while clean water will be stored in the water tank which is connected to your faucet on the countertop. Once you open your faucet, the stored filtered water will flow out of our faucet. Before that, the post filter will purify water again to remove odors as well as sediments.
Of course, membranes are the most important parts for RO systems, because they determine the ability to filter what types of contaminants in our water. Generally, most membranes that are used in commercial RO plants are made from polyamide, acetate and polysulfonate. And the membrane is only made up of a 100-micorn of support layer and a 0.25-microns skin. As a griddle, only water molecules are allowed to pass through the skin.
Generally, water has an amount of dissolved solids. The amount is a constant percentage of dissolved minerals in feed water. For example, if the TDS (total dissolved solids) is 400 ppm, the water purified water by a RO system may have 20 ppm or 40 ppm, which means Reverse osmosis methods can remove 95% or 90% dissolved solids in the feed water. Most RO systems are designed based on TDS of feed water. Of course, the lower PPM in purified water is better.
Reverse Osmosis F.A.Qs
More and more people have realized that their water needs to be purified before drinking and cooking. And many of them buy reverse osmosis systems to purify the water from water companies. However, there are also some people don’t know something about reverse osmosis. Therefore, here, these F.A.Qs may help you quick know something about reverse osmosis.
1.What’s the definition of Reverse Osmosis?
Reverse osmosis use a semi-permeable membrane to separate minerals as well as other contaminants from water. This is because this semi-permeable membrane only allows water to pass through. If pressure is applied to the water that needs to purified. Only water molecules are allowed to pass through the membrane. And all the contaminants are left in its original side. On the other side, RO water is available and clean, safe for consumption.
2. What is the Difference between commercial and household reverse osmosis systems?
Actually, the basic procedure is no different from each other. The only difference is that most commercial or industrial RO systems use many other components to make the RO systems much stronger. For example, pumps are usually used to make them much stronger. And spiral wound membranes are also used to increase the surface area. In a word, commercial RO systems are much stronger but much costly at the same time.
3. Is Pretreatment Necessary?
Of course, the pretreatment is necessary. In a RO system, the pre-filter is used to remove chorine as well as silt that may make the membrane plugged up or damaged easily. Total Dissolved Solids (TDS) are also got rid of by pre-filter.
4. How much pressure is needed to conduct reverse osmosis?
The pressure applied depends on the salt and sediment concentration in the feed water. If the concentration is high, the more pressure is needed.
5. How Pure is the RO Water?
Purity of RO water depends on 2 factors. The first is the rejection ratio of the membrane which is normally between 92% and 99.5%, and the second factor is the types of TDS in the original water which makes the membranes become weak, thus affecting the purity of RO water.
6. How to clean the RO system?
First, you need to disengage the RO tank, and then clean the tank, and then at last wrap up Reverse Osmosis Tank Cleaning. Learn more about this.
7. What Is The Extent of Maintenance to Expect ?
In order to protect the ro system, the pre-treatment filter is needed to clean every month and the whole process only costs about 1 hour. If your feed water contains much dirt, you need to check the prefilters every week to notice if they are blocked.
8. How much does run a RO water filter?
Once you have installed your RO system, to keep it running normally, the maintenance cost is needed. The cost depends on several factors; the purity of the feed water, the cost of replacement filters and labor. If the feed water contains too much amount of pollutants, the membranes are prone to be weakened very soon, so you need to change its filters on a short time basis. If the replacement filters are expensive, this also will increase your cost when you need to change them. If you need to hire some to maintain your system, this will also be a big budget. You’d better change them yourself and the process is pretty easy.
9. Does It Remove Bacteria?
Bacteria are get rid of by the membranes and while at the storage tank, the system use UV sterilization system to kill the bacteria when water is passed through. This process will happen during the cleaning process. Therefore, it is highly recommended to choose an opaque tank or paint your tank black, so that algae cannot grow in it.
10. When or How Long to Change the filters?
Although RO membranes are designed to last several years, the time they last depends on many factors. If you notice a high ion levels in your RO water. This is a sign that you need to change it. Generally, manufacturers recommend to change the filters every 6 to 12 months. Most systems have indicators that can remind you when you need to change them.
Because of the obvious benefits of reverse osmosis, the RO system has become one of the most important and useful technological breakthroughs in the world. It can effectively offer plenty of clean, safe and healthy water at a reasonable price. What’s more, reverse osmosis is not only used to offer drinkable water for us, but also can be used in other areas. The following areas are those areas in which reverse osmosis can play an important role.
Reverse osmosis is able to provide us with plenty of safe water in our house. More and more corporations have realized the huge benefits of RO systems, so they begin to quench their employees thirst by using RO systems. For example, it is estimated that about 1,000 to 6,000 U.S. soldiers are served with RO water by the U.S. military, while NBC are turning to RO water for their operations.
Reverse osmosis system can use collected rainwater as feed water and collected water is also used for irrigation and industrial cooling. Many big power plants need to remove minerals from the water used in the boiler, so RO systems are the best choices. This is because pure water doesn’t leave deposits in the boiler, or the machinery will be corroded and damaged by these minerals. Recently, Singapore announced that they will use RO systems to treat their waste water before re-introducing the waste water into the reservoirs. If the cost can be controlled well, more and more waste water treatment companies will use this method.
In food factories, RO is used to make food liquids thickened. For example, when making orange or tomato juic, RO water can make the juice taste thickened. Reverse osmosis is also used in concentration of whey protein powder production and milk in the diary industry. In the wine industry, RO is used to get rid of alcohol, smoke and acetic acid. It is also used to remove excess water from maple sap. About 80% of excess water will be removed, so the cost of boiling the syrup can be reduced.
If you are an aquarium keeper, you should know tap water is not suitable, because dissolved chlorine as well as other contaminants (like heavy metals, chloramines, nitrogen compounds and phosphates) is in the tap water are not suitable for the artificial mix of sea water.
It is known that hard water will easily cause spotting on our vehicles, so many car wash entrepreneurs RO systems to soften hard water. The RO system can effectively get the minerals in the water removed. Therefore, seldom customers require to make the vehicles dried, reducing the costs.
All in all, you have known how important reverse osmosis is in our daily lives. Reverse is regarded the most effective way to reduce our exposure to waterborne diseases.
Well, if you want to have clean, healthy water to consume and want to pick up the best reverse osmosis system, the above top 5 best RO systems can help you quickly find water you really want.
