Distilled water is one of the most popular forms of treated water on the market today. Water distillation is a process in water purification. In this process, it boils unfiltered or unclean water and lets steam condense into a clean container.
It may seem simple but it is a stringent process that involves appropriate machines and precise steps to produce distilled water. When water is distilled, impurities are removed. It has its strengths and weaknesses, but it's been around for a long time, and the distillation process is a tried and true method that can improve the quality of water significantly.
Distillation is one of the best ways to clean up water if any area has recently experienced a chemical spill, heavy metal poisoning in the water, or bacterial buildup. Majority of the operators of bottled waters utilize a combination of methods in removing impurities from the water source before pouring them into and packing them up in bottles.
This is because a combination of methods ensure far more efficiency in removing water impurities, than one single method. The methods that are widely used in water purification include: reverse osmosis, carbon filtration, ion exchange, and distillation. Out of all these, reverse osmosis is the most commonly used method in water purification; it is used by 40% of the total number of U.S. water bottlers, according to a report by All About Water Filters.
The distillation process basically involves boiling the water and harvesting the condensation. The best way to do this on a large scale is to use a flash-type evaporator. This heats water quickly to a high enough temperature to boil it and then captures the condensation that builds up from the boiling process. When boiled water condenses, it leaves behind any impurities that might have been present.
According to the U.S. Environmental Protection Agency, distilled water is very dangerous for consumption because it is very aggressive in dissolving anything it comes in contact with since it is basically mineral-free. Distillation is probably the oldest form of cleaning water. It is not a chemical reaction as many think but a physical separation process. It is the process by which components are separated from liquid by using evaporation and condensation. If evaporation and condensation seem familiar from elementary science, it is because it is the same process, just different channels.
To explain, let us look at each process one by one: Evaporation is the process by which liquid state turns into gaseous state. This is known as water vapor or steam. For example, water vapor in the air is from surface water such as oceans, seas, lakes, and even puddles. Imagine the other particles that come with it. Steam or vapor is clean, pure water. When unclean water has passed through the evaporation process using boiling point heat, it passes through another process or phase in the water cycle. Converting it back to its liquid form is called the process of Condensation. Science class discussion will tell you this is the process by which clouds are formed. Without clouds, the next phase in the cycle cannot be accomplished.
Fog is a form of condensation. The 3rd phase in the water cycle is called Precipitation. When there is enough condensation, water falls to the earth in the form of rain, sleet, snow or hail. If this sounds familiar, it should be. It is the same process used in distilled water that we drink, without the precipitation part. Water distillation involves evaporation and condensation.
Moreover, distillation removes most contaminants, but not all of them. The process removes just enough of the water's other substances to render the effect of such small amounts ineffective. Water distillers are a safe and affordable method when it comes to treating water, according to Puricom. Nowadays, manufacturers offer different designs which can sometimes alter the resulting taste of the water from certain distillers. That is why, before purchasing, consumers must first read reviews to learn how a specific water distiller of their choice works, and to ensure that it has a suitable capacity for their family.
