Water Purification Versus Filtration
When it comes to home treating water there are some key differences in how it can be done, and these are either water purification or water filtration. Filtered water has physical impurities removed such as dirt or sand, while purification strives to remove biological components.
Usually, purification is done after filtration, or the device has a filtration layer before the purification stage. The biological components that are removed with purification typically include germs, viruses, and even minerals. But what are these types of water purifiers?
Water Distillers
Purifying water by means of distillation has been an effective method for a very long time. It’s maybe the most famous way of cleaning water as it has been used in many survival scenarios when cleaning water off the grid implied using fire to distill. Now there are devices that can help do just that, and they usually come with a boiling chamber, a cooling system with pipes, and a storage tank to catch the evaporation.
Distilling water removes somewhere close to 99.9% of contaminants, including microorganisms. The resulting water is highly purified and consistent results are what a distiller will offer. This method, however, may not be entirely convenient in a home setting, but it can be put into practice. It may take a while and the energy needed for this can be large even when the results speak for themselves. There are also natural methods to distill water, by using the sun as the energy source. Solar-powered water stills purify water in the same fashion, but it could take longer, but this too has seen advancement with technology.
UV Water Purification
Keeping in line with using the sun for water purifying, UV technology has become a rising technological innovation. Although UV purification does not function the same as distillation, it nevertheless uses the sun to clean water, especially viruses and microorganisms. UV purification works by implementing the use of a UV lamp tube through which water is sifted and exposed to ultraviolet light.
This is how bacteria and viruses are killed and rendered inactive. The physically inactive viruses are still in the water but have no effect. This method is highly eco-friendly and has many advantages, especially with well water. A technologically advanced device that is very potent in cleaning water without using any chemical components. Its low cost of maintenance and high purification results make it very useful and practical. UV water purification also helps greatly that it does not alter the water’s taste if this is something desired. It also uses very little electricity to power the purification process, comparable to a light bulb.
Water Purification Through Deionization
Deionization is a process by which water is purified by removing all dissolved solids. Water has to flow through two ion-exchange mediums in order to replace a good portion of its mineral ion content. Among the minerals that get taken out with this process, we can count iron, copper, sodium, calcium, and even some anions like sulfate and chloride.
Hydrogen ions attach to calcium and magnesium making it impossible for them to come together. What this does is prevent scale build-up from the water source, which can affect water using devices. The same hydron ions replace any positive metallic ions by exchanging sodium ions. This exchange of ions is possible with the use of the deionization medium that comes in the form of a resin bed.
Long-lasting durability is what makes the resin bed a useful medium of purification as it can be used for quite a while before it needs to be replaced. Not only that but it also recharges regularly as part of its maintenance requirement.
Reverse Osmosis Purification
One of the most famous methods of water purification, one that is acclaimed for its efficiency is reverse osmosis purification. A fairly more complex device that requires some insight into the installation in a home. An RO purification system uses high-pressure water pumps to pass water through a semipermeable membrane.
Through the process of reverse osmosis, water is purified by the removal of many contaminants like chlorine, lead, fluoride, and dissolved solids such as arsenic.
One of the many advantages of RO purification is the improvement of taste and smell, as well as removing waterborne microorganisms. A reverse osmosis system is capable of offering a wide range of purification options especially as it can link with other types of purifiers to form multiple barriers against contaminated water.
Wrapping Up
Even as water filters and water purifiers grow and become more technologically advanced, water safety is at the center of this evolution. Knowing the difference and implementing the right system will provide the best results, based on water quality in a specific area. Purifiers tend to be seen as less efficient, but the name alone can fool you. Reverse osmosis purification is one of the most powerful methods of cleaning water and its efficiency is undeniable.
