Note that distillation is different from the process many municipalities recommend for purifying your water. Simply boiling the water will kill bacteria and microbes in it but it will not remove chemicals and other impurities like minerals. Both distillation and reverse osmosis provide clean drinking water but only one reverse osmosis is practical for residential purposes.
Now, you may be scratching your head. So is reverse osmosis water distilled, and vice versa? First things first, both methods when done correctly do provide clean and safe drinking water.
Distillation, however, does not remove volatile chemicals like chloramines with the same effectiveness as reverse osmosis. The most accurate way to describe reverse osmosis water is filtered.
Distilled water has been boiled and the condensation has been captured then turned back into water. Things become a lot clearer when you consider what water commercially produced using either method is typically used for.
Bottles of distilled water are typically used for applications in which minerals would be an obstacle. You see, the water supply of most municipalities contains plenty of minerals. These minerals can adversely affect things like steam irons and indoor aquariums.
Certain laboratory experiments also require distilled water. Residential water distillers do exist but they use a lot of energy and are much less common than reverse osmosis filters. With a reverse osmosis filter, getting pure water is as simple as opening your faucet. The process runs without much input from you, whereas the distillation process is much more involved.
Distillation also typically produces quantities of water far less than what most people need. For this reason, at American Home Water and Air, we carry and service reverse osmosis systems. Earlier, we mentioned that both reverse osmosis and distillation remove minerals from water.
This water is also called soft water because all the hardness is removed by the de-mineralization process. Generally, soft water is used in boilers to produce the steam because soft water does not create the problem of scaling in the boilers. Soft water is also used to feed purified water plant. Purified water is highly pure water then de-mineralized water and produced using DM Water.
To prepare the purified water, soft water is passed through Reverse Osmosis membrane and ultraviolet light. Reverse osmosis removes the soluble impurities from the water by passing water through its membrane having pore size 0.
Ultra Violet light removes microbes from water making it free from microbial contamination. Purified water is used for pharmaceutical manufacturing and to produce water for injection. Purified water is distilled from multi-column distillation plant and collected by the condensation process. Both DM water and purified water have their own specification to be passed for their quality. De-mineralized water should pass the hardness and pH test only while purified water has various parameters like description, pH, conductivity, hardness, heavy metal, iron, nitrate, sulfate, residue on evaporation, microbial limit test etc.

Ankur Choudhary is India's first professional pharmaceutical blogger, author and founder of Pharmaceutical Guidelines, a widely-read pharmaceutical blog since Because those pores are so small, almost all contaminants are trapped and cannot pass through.
While RO water is not truly demineralized, the process does remove a significant portion of mineral ions that are too large to pass through the membrane. One of the best and most cost effective ways to produce demineralized water is to combine RO and DI systems. By passing the water first though carbon and sediment pre-filters and then a reverse osmosis membrane, very few contaminants and only a small number of mineral ions typically remain.
This treated water called permeate can then be processed by the DI system, which will remove any remaining ions. This treatment method produces high purity water that can be used for a range of industrial and commercial purposes. Demineralized water can be used for a range of industrial purposes, although it's available to consumers as well. It's used in car batteries and automotive cooling systems, as well as in cooling towers, boilers, and other systems where any minerals in the water could build up on surfaces and cause blockages and other problems.
Demineralized water or deionized water is also required in pharmaceutical manufacturing and cosmetics industries. This type of water is used for electronics manufacture and a number of industrial processes, such as laser cutting. Most people don't drink demineralized water because they think it tastes "flat. There is some question about whether or not it's safe to drink demineralized water, but most scientists agree that it's not actually dangerous.
Most people do not get a significant amount of minerals from the water they drink, and drinking water without minerals won't leech minerals out of your bones or cells. The reality is that most people prefer drinking water with some minerals in it, and it's usually less expensive than demineralized water. Plastic Filter Housings 2. Home What Is Demineralized Water?
