Water Hardness

What is water hardness?

Water hardness refers to the total concentration of divalent metal cations in water. Divalent cations are positively charged metal ions with a charge of 2+. Dissolved calcium ions (Ca2+) and magnesium ions (Mg2+) are the two principal divalent cations that create water hardness.

Distilled Water

Distilled water has for long been the most common type of purified water, and even with the emergence of other processes of purifying water, it still remains one of the purest forms of purified water.

In this comprehensive guide to distilled water, we’ll dig deeper into what it is, its uses, benefits, specifications, how it’s made and much more.  

What Is Distilled Water?

Distilled Water and Water distillation

Distilled water is purified water formed when contaminated water like well water, tap water or seawater is heated into vapor, then condensed back into liquid form. It’s one of the purest types of water as it’s free of almost all water impurities.

What is Distillation?

Distillation is a physical process of separating mixtures through evaporation and condensation. The process relies on the unique boiling points of the components in the mixture. Water distillation, in particular, is a form of water purification process that physically separates water from its impurities.

Fluoride In Water

In this article, we will demonstrate the important things you need to know about fluoride in water.

Here you will find:

Why Is There Fluoride In Water?

Fluoride in water and Water Fluoridation

Fluoride is common in our tap water as well as in many sources of drinking water. It’s a natural mineral that exists in the earth’s upper crust and occurs naturally in surface waters and groundwater around most parts of the world.

In surface waters, it occurs naturally from the weathering of rocks and soils containing fluoride compounds while in groundwater, it occurs from leaching of bedrocks with fluoride content.

However, the fluoride in our tap water is often from the additional fluoride added to the community water supply – a process called fluoridation.

This is usually done in many areas of the world where there’s a low concentration of fluoride in the drinking water.

Reverse Osmosis System Cost

Reverse Osmosis System Cost

In this article, we are going to break down the cost of owning a reverse osmosis system in the US from the initial price to the cost of installation and maintenance. We provided the estimates for the countertop, under-sink, and whole-house RO systems.

RO system cost = Initial price + Maintenance Cost

Reverse osmosis systems have become an essential part of our lives when it comes to water filtration and with the ever-increasing demand, we continue to see an increase in the number of brands and suppliers of RO systems in the industry.

Consequently, the price of RO systems now varies widely with each brand striving to offer a more competitive price tag than its competitors.

However, the initial price of an RO filtration system is just one part of the equation as there are other expenses you will need to factor in which include installation and maintenance.

Therefore, if you are weighing your options and wondering how much it will cost you to own and manage an RO system, then keep reading to learn more.

pH Of RO Water – How To Remineralize RO Water

How To Remineralize RO Water

In this post, we will take an in-depth look at the pH of RO water and how to remineralize RO water, everything to do with RO water remineralization.

We also give you a brief review of the top 8 mineral filters for RO systems that are worth considering.

Once you are done going through this article, you will have a great insight on how to remineralize your RO water and what type of mineral filter to get.

Reverse osmosis provides an effective and reliable way of purifying water and while it eliminates all contaminants and unhealthy substances, it as well strips out all the mineral content present in water.

The only way to circumvent this is remineralizing the RO water to get the essential minerals that the body needs and still enjoy contaminant-free water.  If you are wondering how to go about it, then we got you covered.
