Any money that you intend to spend on a water purifier has to be put to use in a judicious manner. The reason being the health benefits that arise from drinking pure water. Apart from this there are various reasons for you to continue searching for a water purifier. The onus lies on providing safe drinking water
- To be safe from life threatening diseases that are known to arise from contaminated water
- The weird taste of chlorine in water might be of concern as municipal corporations incorporate chlorine into water that makes its way on to our homes.
- Scaling, scratches and ugly stains on the surface of your kitchen utensils.
By a water purifier guide you are able to purchase a proper one based on the needs of your home. In areas people inquire about water softener price that goes on to makes the hard water soft. Before casting our mind back to the various types of water purification technologies, we need to have an idea about the various types of impurities that are present in water. Based on that we can go on to choose a water purifier based on our needs.
The various kinds of impurities that is present in water
The kind of impurities that makes it way on to water does depend upon the source and even the distribution medium. Common source of water are the lakes, municipal corporations or tankers to name a few. The quality of water would depend upon the biological or chemical properties that are present in water. Presence of virus or bacteria also contributes to the hardness of water in a big way.
Any source of water that makes its way on to your home is from underground, in the form of water tankers or deep bore wells then it is a sure shot case of hard water. In hard water the percentage of dissolved solids like calcium, arsenic or heavy metals is at a higher level. The presence of dissolved impurities make hard water unfit for human consumption. On the other side the water that is obtained from river beds has an efficient storage and delivery system that is termed as soft water. This form of water has to be purified before it is deemed fit for human consumption.
The various types of water purifiers
RO purifier
A RO system works in an opposite manner of osmosis. The water molecules are pushed from regions of higher TDS to regions of low TDS. This can be achieved by applying external pressure in the form of a water pump where the natural flow of water is reversed. The dissolved impurities along with water are collected in a separate chamber.
For purifying water that has a high TDS level this water purifier is suggested. Though a major loophole of this method is that a lot of water is wasted.
UF
Ultra-filtration as the name suggests use a semi permeable membrane to purify water. Now a lot of people might argue that RO and UF are the same methods of purifying water. But there is a difference that UF uses a membrane with large pores in order to purify water. On the other end a RO system uses a membrane with smaller pores.
The main benefit of this water purifier is that it can work without electricity as the pores are larger. Even the water can pass through it relying on the force of gravity. A notable feature is that no wastage of water occurs by this method. But loopholes are there as the dissolved solids cannot be removed or TDS level cannot be reduced. For this reason, they are not suitable for purifying hard water.
UV water purifier
Pretty much like the name sounds this sort of water purifier relies on the use of UV rays to obtain purified water. It works when you end up throwing high intensity rays on water that kills the harmful bacteria along with virus present in water.
This is a form of water purifier that can only be used in areas where the TDS levels of water are low. Still if the water has low TDS levels and is contaminated with virus or bacteria then you can use a combination of UV+ RO+ UF
The task of choosing a water purifier
The mention of water purifiers brings forth RO technology and it is common that people associate RO with water purifier. So, when we are discussing about water purifier people are of the opinion, they should purchase RO water purifiers. They tend to do so without giving any consideration to other parameters like TDS levels of water or the source of water.
You might be aware that RO system of water purifier is only needed once the water coming into your office or home has TDS levels greater than 500 ppm.
In the market of late numerous types of water purifiers are available. They go on to incorporate various technologies and the presence of numerous brands makes the choice a difficult one. Once again, the fact comes to the fore that you should only purchase a RO water purifier if the level of TDS is more than 500 ppm.
No need to use a RO water purifier is the TDS level is less than 500. The reason being if the TDS level is low a RO water purifier is expected to reduce it further. It would point to the fact that the water would be deprived of essential minerals like calcium or magnesium that are of essence for our good health.
Though water purifier companies go on to boast a lot about the new technologies, but the basic technology are the ones mentioned above. The above-mentioned checklist will be of considerable help.
Conclusion
The biggest criteria in the choice of a water purifier evolve down to the quality of water with the presence of impurities make its way on to your home or office. With the aid of water purification installation you can purify the water.
