At Essential Pure Filtered Water, we are proud to offer you purified water.

What is purified water?

Purified water refers to all types of water from which chemicals are removed via a variety of different processes.

The simplest is the inexpensive home water filter which helps remove SOME of the chemical compounds found in tap water. Other more expensive filters such as a reverse osmosis technique, which helps shunt chemicals in the water to the side while leaving the remaining water free of most commonly found chemicals. Distilled water and deionized water are also considered purified.

Distilled Water

Distillation of water is generally accomplished by boiling the water and any chemicals present get separated in the process. As water steam or vapour rise from a boiling batch, it is captured in tubes and allowed to cool back down to liquid state. Such a process can remove many chemicals from water, since they won’t turn into a vapour state. Often, water is double distilled.

Deionized Water

Another form of purified water is deionized water. The process to deionize water is less expensive than distillation. Special chemicals are added to the water, which bond to the dissolved salts. These remove the chemicals, leaving behind water that is very pure, even free of most bacteria. Deionizing water takes less time, and requires less work, but for human consumption, you’re more likely to see distilled water in stores than deionized water.

There are a variety of filtration methods to achieve purified water. Not all methods result in the purified water that you can get from distillation or deionization. Some trace elements may not be filtered out using other processes, but generally most purified water sold for drinking has lower levels of chemicals than does normal tap water.

For years, there have been arguments over whether drinking filtered water, as opposed to tap water, is beneficial. In areas where high levels of unsafe compounds have been noted in water, it may be far better to choose purified water. In emergency settings, it can be imperative to drink only bottled water, if sewage has contaminated the regular water supply.

Sometimes, the trace minerals in tap water can be beneficial. You may lose calcium, fluoride, and a variety of salts when you drink purified water instead of water from the tap. There are arguments for and against the consumption of purified and/or tap water, and most people should take a look at these arguments before making a decision on which water to drink.

There is less argument about the use of purified water for various machines and in a variety of chemical applications or laboratory work. Some scientific experiments require water that is exceptionally pure in order to be certain that any trace elements remaining don’t affect experiments or testing results.

In various industries, water that has most metallic salts removed via deionization or distillation can be preferred so that mineral buildup doesn’t occur in machines or their constituent parts.

Even on the home front, you might want to use distilled or deionized water in your coffee pot, iron, or humidifier to prevent minerals from collecting in these devices and reducing the life of these appliances.

Alkaline water provides a great way to balance acidity levels in the body.

The pH scale ranges from 0 to 14, with 0 being the most acidic, and 14 being the most alkaline (or basic).

Regular water has a pH of around 7, right in the middle of the pH scale. Alkaline water, however, has a pH of 8 or 9, well above standard water.

Since the human body has a pH level of about 7.4, drinking regular water will not have any acid reducing effect. Alkaline water, though, rich in alkalizing ingredients such as calcium, silica, potassium, magnesium, and bicarbonate, helps bring down the body’s pH levels with its acid neutralizing qualities. It helps the body cleanse to the cellular level, while also boosting the immune system.

Reverse osmosis (RO) is a membrane-technology filtration method that removes many types of large molecules and ions from water, by applying pressure to the water when it is on one side of a selective membrane.

The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be “selective,” this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as the solvent) to pass freely.

In the normal osmosis process, the solvent naturally moves from an area of low solute concentration (High Water Potential), through a membrane, to an area of high solute concentration (Low Water Potential). The movement of a pure solvent to equalize solute concentrations on each side of a membrane generates osmotic pressure. Applying an external pressure to reverse the natural flow of pure solvent, thus, is reverse osmosis. The process is similar to other membrane technology applications. However, there are key differences between reverse osmosis and filtration. The predominant removal mechanism in membrane filtration is straining, or size exclusion, so the process can theoretically achieve perfect exclusion of particles regardless of operational parameters such as influent pressure and concentration. Reverse osmosis, however, involves a diffusive mechanism so that separation efficiency is dependent on solute concentration, pressure, and water flux rate. Reverse osmosis is most commonly known for its use in drinking water purification from seawater, removing the salt and other substances from the water molecules.

There are two ways that you can take in minerals, you can either eat them or drink them. Your body then uses them to keep you in good health. A diet lacking in proper minerals can lead to poor health.

The quickest and easiest way to obtain what you need is by drinking good old plain mineral water.

Minerals are essential to maintain a healthy human body. If your drinking water lacks these minerals, then your body will get them from other sources within your body. This can leave your body cells depleted.

Experts recommend that you do not drink demineralized or distilled water on a regular basis. Doing so can be bad for the digestive system and can also lead to mineral deficiency in your body.

To decide whether or not mineral water is healthy for your body, you will have find out what exactly is in the water.

However, as it has a number of nutritional properties for your body, mineral water is generally considered healthy. Apart from this, you should be aware that removal of these minerals or lack of these minerals in water could leave you with mineral deficiencies.

Still not convinced that mineral water is healthy and worth drinking?

There are several problems with bottled water. It is heavy and difficult to transport from the store and creates massive waste. So where can you get an unlimited supply of natural mineral water?

Some people choose to install a residential reverse osmosis system. This works by forcing the water through a porous membrane. In this, the size of the pores would determine which substances flow through and which get blocked.

The problem is that minerals generally tend to be larger molecules and so the reverse osmosis method can actually reduce or block the mineral content in the water to little or none.

A better option would be a filter system. Most often known as selective filtration, this method takes out the contaminants but leaves the trace minerals in the water. This method is very cost effective, much cheaper than buying bottled water. You have access to an almost unlimited supply of great tasting, chemical free water for cooking, drinking, bathing, and other water needs.

UV radiation from ultraviolet water systems alone is not suitable for water with high levels of suspended solids, turbidity, colour, or soluble organic matter. These materials can react with UV radiation, and reduce disinfection performance.

Water turbidity makes it difficult for the Ultraviolet radiation to penetrate water. If your water supply has these characteristics, a Sediment Pre-filter (5 micron or less) should be installed before your UV water purification system to remove particulate matter prior to UV water disinfection.

Ultraviolet radiation can be used as a pre-treatment or polishing step to sterilizing and disinfecting water. UV systems are typically used to pre-treat a water supply that is considered biologically unsafe (lake or sea water, well water, etc).

The UV disinfection process is a non-chemical method for destroying microorganisms by altering their genetic material, and rendering them unable to reproduce.

There are several advantages of using UV rather than a chemical disinfection solution (such as chlorination):

• No known toxic or significant nontoxic byproducts
• No danger of overdosing
• Does not require storage of hazardous material
• Adds no smell to the final water product
• Requires very little contact time

Applications include private wells, camp grounds, hotels, bottlers, aquaculture, hospitals, food, cottages, restaurants, breweries, water systems, laboratories, marine, pharmaceutical, dairies, and many other applications.

Distilled water has a much higher purity level than filtered water and deionized water. Uses of distilled water are many in research studies, scientific laboratories, and hospital applications, where sterilized water is required.

The distilled water pH level has something to do with the distillation process of water. Before discussing about distilled water pH directly, let’s take a look at what distilled water is, and the procedure for preparing it.

What is Distilled Water?

Water purified with a distillation method results in distilled water. By distillation, we mean the water purification system in which water is boiled first to form steam in an enclosed apparatus called ‘still’. Then, the steam is condensed in a sterilized container, called a condenser.

During the boiling step, all microbes are killed and the impurities are left behind, while only the steam is collected in the condenser. Regardless of the source of the water (river, lake, ocean, etc.), the purity of distilled water is found to be more than 99 percent.

Distilled Water pH Level

Most people assume the pH of distilled water to be neutral or near neutral. Thus, ‘is distilled water pH neutral’ has been a common query among science students, who have just started learning chemistry.

With respect to the preparation procedure and expelling of gases during boiling, it is understandable that the distilled water pH scale falls in the neutral range (pH 7). Nevertheless, in most cases, the pH of distilled water is slightly acidic (around pH 5.8). Some sources even report the distilled water pH level to be as low as 5.5. Generally speaking, the pH of distilled water is below 7 or neutral value.

No doubt, the ideal distilled water pH level is 7. But, practically, it is very difficult to get distilled water with neutral pH in regular equipment setups. The slight acidity is due of the carbon dioxide (from air) that gets dissolved in the water during condensation, forming carbonic acid.

At low temperatures, dissolution of carbon dioxide takes place until it achieves a dynamic equilibrium with that of the atmosphere. To be more precise, the amount of carbon dioxide absorbed during condensation equals the amount expelled during boiling. Ultimately, the carbonic acid increases the acidity of distilled water and lowers the pH level to below neutral value.

Double Distilled Water pH Value

Double Distilled Water, referred to as ddH2O in abbreviation, is used when there is a need for an increased purity level, more than that of the normal distilled water prepared by single distillation of water.

As the name suggests, water is subjected to 2 distillation cycles in order to produce double distilled water. It is generally used for molecular biology experiments that require optimal sterility.

Similar to single distilled water, the pH level of double distilled water is slightly acidic (below pH 7). The reason remains the same, absorption of carbon dioxide by the steam during the condensation step.

So, this was a brief overview concerning distilled water pH level. I hope you have understood the phenomenon behind the acidity of distilled water, despite the sophisticated procedure. For bringing the pH to neutral value, a gallon of distilled water requires 1/8 teaspoon of baking soda. It is not unusual to use distilled water for drinking purposes. Some households use the process of distillation for purifying water, especially in areas where tap water or municipal water is not safe for drinking. Considering the fact that distilled water is free of dissolved minerals, ions and gases, it tastes bland.
