Water Purification Process

Water is essential for survival. All living things on this Earth need water in order to sustain themselves. Our body is made to function on water and without it, we cannot continue to perform at our maximum potential. Water is the key to four major functions within the body. This includes cell life, chemical and metabolic reactions, the transport of nutrients and the removal of waste, as well as the regulation of body temperature. It is for these reasons that water is so beyond important for us. Upon the consumption of water, it is necessary that one should not just pay attention to how much water they are drinking daily, but also where their water comes from. Water comes in all different types of sources naturally and just because it is water, does not mean that it is always good for us. There are certain types of water that will actually be incredibly harmful to your body and for this reason it is critical to do your own research on what kind of water is the best water out there for you. If you are super busy and do not have the time to do extensive research than look no further! This article will give you the lowdown on the best water you should be drinking, to ensure the healthiest hydration possible!

The Issue with Other Types of Water

When choosing the water that will best hydrate you while keeping you healthy, it is no secret that purified water takes the lead. It excels in ways that other forms of water like distilled, tap, spring, etc. cannot. Before I give you the why on what makes purified water the best choice, let’s give the basics on why other kinds of water just don’t cut it. Let’s start with tap water. Regular tap water is by law safe to consume, but scientists still argue firmly that it is not the best way to hydrate yourself properly. It comes from a municipal source and no other ingredients are added to it, but what is considered safe and usual (like fluoride). Yet this water can still be legally safe while harboring a certain concentration of contaminants and bacteria. For example, a new study performed by the Environmental Working Group or (EWG) stated that they had found alarming levels of chromium-6 in drinking water that approximately 200 million Americans drink from all states. Chromium-6 is known as an odorless and tasteless metallic element that occurs naturally within the environment. It is found in all living things from rocks to plants, and to soil. The breathing in of the particles can cause lung cancer. Liver damage, reproductive problems, developmental harm, and poses a greater risk on infants and children. In all chromium-6 is known to be incredibly bad for your health. In addition, tap water tends to leave behind a very mineral and heavy taste to it that makes it unpleasant to consume daily. Now let’s move on to distilled water. Distilled water is actually a lot safer to consume than tap water due to the fact that it goes through a rigorous filtration process to rid it of its contaminants. The bad side? Well this filtration system rids the water of all its beneficial minerals. I mean what would be the point of drinking distilled water if you wouldn’t actually be able to reap the benefits of drinking water? Spring water is another type of water that should not be enjoyed for everyday consumption. It comes most commonly in the form of bottled water, which many people tend to get their daily water intake from. Yet, it is a mystery in terms of how safe it actually is because although it is labeled as natural spring water, many bottled water companies have been able to get away with extracting the water from other unknown sources. This makes our understanding of how safe this water is a lot more muddled. In addition, the NRDC aka the Natural Resources Defense Council, performed many studies on bottled water and came to the conclusion that bottled water actually harbored a lot of contaminants from coliform to arsenic to phthalates. In other words, spring water is no go for the optimal safe drinking water. For these reasons we now stress the why on choosing purified water!

Why Choose Purified Water?

Water ranges from all different types. There is tap water, purified water, distilled water, spring water, and more! With an intensive amount of research being done, it can be concluded that purified water is actually the best water to drink. Research done on other types of water have shown that despite the fact that other kinds of water may be safe to drink within legal terms, this does not make it completely safe for the body. At the end of the day the amount of filtration and purification that these types of water go through cannot compare to purified water. For this reason, purified water remains as the top of the line water for the safest consumption. In addition to this benefit, you can actually taste how pure purified water is and its taste is most preferred over any other type of water! If you are still a bit skeptical on just how much cleaner purified water is then no problem! We will be going over the process in great detail, but in a nutshell, one could say that purified water goes through a majorly, complex system to completely remove any sort of contaminants or gases from the water. The purification of water can actually work to reduce the concentration of certain particulate matter like suspended particles and gases, parasites, bacteria, algae, viruses, fungi, and more! This system allows the water to not only taste better but be incredibly safe to drink as well!

The Process to Crisp, Purified Water
The process to crisp, purified water is most definitely not a one-way path. One can take many different approaches and methods to reach this desired water. The many processes that purified water can go through to become purified include physical methods such as filtration and sedimentation, biological processes such as slow sand filters, and biologically active carbons, or other chemical methods like flocculation and chlorination. We will not be going over the detailed process of all these types of methods, just know they do exist! One process we will be focusing on heavily is the many different methods associated with filtration.

Filtration for Purified Water


Course Filtration – In the process of course filtration, the main objective is to remove coarse suspended solids within the water that could deposit on the filtration equipment creating corrosion sites. This type of filtration can also be known as particle filtration and can catch contaminants as little as 1 mm sand or as big as 1 micron.

Micro Filtration – Microfiltration is another type of filtration that is used to catch incredibly small contaminants. It holds the name of micro filtration because its complex system is used to catch and sift out any contaminants that are considered to be not visible with the naked eye. It is best used for filtering out the bacteria.

Ultrafiltration – Ultrafiltration is most commonly used as a pre-reverse osmosis process in which it reduces the silt density index of water. This helps to remove particulates that can harm or damage the reverse osmosis membranes. It utilizes a medium that is fine enough to retain colloidal particles, viruses, or large molecules. It is best known for removing pyrogens, endotoxins, DNA, and RNA fragments.

Reverse Osmosis – Reverse osmosis is considered to be the most refined degree of liquid filtration. It utilizes a porous type of material (instead of a filter) that acts like a sieve, working to separate molecular-sized particles. It begins with the use of a high-pressure pump to increase the pressure on the side where the non-purified water is. It shoots the water through the sieve, allowing for around 95% to 99% of the other particles and contaminants to be left behind. The rejected salt and contaminants are then pushed through a stream known as the reject stream and ends up being drained. The clean water then ends up on the other side of the sieve and is now known as the product water. Reverse osmosis is very well known for removing a myriad of contaminants and particles such as dissolved salts or ions, particles, colloids, organics, bacteria, and pyrogens.

Other Methods
Activated Carbon Adsorption – This operates almost like a magnet to remove chlorine or organic compounds. This method is based on the adsorption of contaminants onto the surface of a filter. It works to effectively remove certain organics that can create unwanted tastes and odors (hence why purified water tastes so good) and can also aid in removing chlorine, fluorine, and radon from the drinking water.

Contaminants to Watch Out For
In addition to getting a better understanding of the many complex processes used to make purified water the safest in terms of drinking water, it is also important to give a little background on the type of contaminants one should never want in their water. With the processes laid out above, these methods are able to effectively remove a majority of these contaminants so that you can rest easy knowing that you aren’t consuming them. Having an understanding of what type of contaminants are sitting in your water can also help you to make more informed decisions about where your water comes from and what it should not have in order to be considered purified.

Regular drinking water should not have…

Particulates: Silt and debris which can be removed by passing water through a 10-20 micron filter.
Microorganisms: This means bacteria. Bacteria are a very serious threat to your drinking water. Their growth rate, size, and robustness require a very unique and complex system in order to be rid of. This is why purified water remains the best choice. Purification systems help to detect bacteria, inhibit growth, and efficiently remove the bacteria while also killing off any secretions or cellular fragments that the bacteria can leave behind.

Endotoxins, pyrogens, DNA, and RNA: These are the cellular fragments and by product left behind by bacteria.

Dissolved Inorganic Elements: This includes a myriad of elements such as phosphates, nitrates, calcium, magnesium, carbon dioxide, silicates, iron, chloride, fluoride, and any other man made or natural chemicals. The existence of such elements in drinking water pose a threat to the hardness of water and the alkalinity/acidity aspect as well.

Dissolved Organic Elements: This includes pesticides, plant and animal remains, or plant and animal fragments.

The application of the mentioned processes above as well as other water purification processes allow for purified water to retain a reputation as being the best and cleanest water out there. The many diverse processes allow for unique ways to extract harmful contaminants and particles that occur naturally within our water. It is so important that when hydrating ourselves we take the time to understand that water is very much natural and prone to all naturally occurring elements (both good and bad) that exist within our environment. It is our responsibility that we acknowledge the many kinds of water and what they can do for our health so that we can take the necessary steps to protect ourselves and keep the risk of harmful illnesses at bay. It is important that we understand that while water itself is good for us, the many things found in water and within nature are not exactly the best for our bodies. Choosing to drink purified water is choosing to live a healthy and hydrated life. Be smart about the water you decide to put into your body and then begin to see all the amazing benefits that water can give your body. Making these informed and researched decisions now means a happier and healthier future for not only you, but your family as well. Don’t be misinformed now that you have read this article and start inquiring about the water that you are drinking currently. Who knows maybe you need to change the kind of water you are drinking currently and doing so now may help you immensely in the future!
