In UV purification, water is passed through a closed chamber with a high UV lamp. This UV lamp produces high intensity UV rays which kill or deactivate all disease-causing microorganisms like bacteria, viruses, pathogens, etc. This water is then packed and supplied to the local areas in convenience stores in a bottled form. Though the origin of Purified Water is the same as Filtered Water, the former is an improved version of the latter.
How purified water is manufactured is a long and complex one compared to ordinary Filter Water. The processes are lengthy and involve chemical reactions of displacement, reverse osmosis, deionization, etc. It uses cutting-edge technology and gives the best to its consumers. It can also be speculated that Purified Water is the next step performed after Filtered Water is produced. And what do they do? They are Reverse Osmosis and Ultrafiltration, respectively.
Pushing impure water through a semipermeable membrane to get pure water on the other side is the standard mechanism of both.
However, UF filters bacteria, viruses, and parasites but retains minerals through that membrane, while RO does not. RO removes dissolved solids like natural minerals and harmful heavy metals like lead, mercury, arsenic, etc. Both in combination give the purest drinking water. The addition of minerals is called Mineralization. These minerals are Iron, Calcium, Magnesium, to name a few. They eliminate any deficiencies that a person may have by drinking them.
Chlorine is a disinfecting agent. It has been known for its purification ability since time immemorial. Water supplying agencies and municipal corporations worldwide add Chlorine to make water infection-free.
However, the smell and taste of it are not suitable for us. Hydration is a concern for everyone, which means having a reliable, drinkable water source is key. Purified water is available through advanced technology that removes chemicals, contaminants, and other impurities that are often still found in tap water and from the production of plastic bottles.

The EPA sets national drinking water standards. The EPA has set a legal limit for how many of each of these contaminants can be present in the water, and it still is safe for human consumption. It can be poured into a bottle or jug, labeled as drinking water and sold at your local supermarket. Filtered water aka spring water or most bottled water brands found in grocery stores also is regulated for safety by the Food and Drug Administration and the EPA.
But again, all filtered water is not alike. Filtered water may have originally come from a municipal tap water source or, if marketed as spring water, from an underground source. The water is then run through some type of filter. Some manufacturers may go a step further and use a micron filter to remove additional chemical contaminants and microbes, but not all do, so the only way to know for sure in the case of bottled water would be to read the label and find out more about how the water has been treated, or call the manufacturer.
The many impurities and contaminants that are removed from water during the purification process include:. While these four processes differ significantly in how they purify water, they are able to provide similar results. In order for water to be classified as purified water, it must have lower than 10 PPM, which means that around 99 percent of all contaminants must be removed from the water.
Purified water is considered to be the healthiest type of water , which is why it comes with many notable health benefits. While the EPA has set guidelines that require public drinking water to be rid of at least 90 percent of contaminants, different states have their own guidelines. Even though state guidelines for public drinking water must be at or higher than the 90 percent removal rate for contaminants, some states have stricter regulations than others.
Drinking water that has been purified from 99 percent of contaminants is always going to be healthier than drinking water that still contains up to 10 percent contaminants. Ultra pure water contains no electrolytes, which your body needs. A deficiency in electrolytes can lead to high blood pressure and other health problems. There are some issues with purified water that you should be aware of before you drink it.
Even though purified water is healthy, drawbacks do exist. These two terms are typically used interchangeably but are actually somewhat different. Even though both types of water are filtered, purified water goes through additional purification processes , which can include everything from distillation to reverse osmosis.
