Drinking clean water is extremely essential to maintain health and avoid water-borne diseases. A good water filter can ensure that water is free from any unwanted foreign particle and tastes good.

Nanotechnology is a technique that exploits nanoscopic material to get clean water. The process is used for removal of sediments, chemicals, salts, bacteria, and other pathogens. It has been identified as a technology that could play an important role in resolving problems involving water purification and purity.

Water purification systems use different techniques like boiling, filtration, distillation, chlorination, sedimentation, and oxidation. The main features that make nanoparticles effective for water treatment make chemical and biological reactions easier.

The benefit of using nano filters is that it needs less pressure to pass water across the filter. These filters are more efficient and have an incredibly large surface area and volume which helps in the particles become stronger and durable. Nanoparticles developed by Nano H₂O have a three-dimensional porous structure that will help the membrane in order to pass water.

Type of Water Filters and Their Uses

1.   Water purification systems provide better smelling, cleaner looking water by removing chlorine and bacteria. Water may have different types of impurities that come from different sources and distribution medium of water. The common sources are rivers, bore wells and harvested rainwater. Borewell water contains chemical impurities like lead, arsenic, etc. So, if you are getting this type of water, you need to buy an RO filter that will help in reducing the hardness of water due to the presence of salts, calcium, and magnesium.

2.    The ultrafiltration technique uses a membrane with much larger pores than the RO water filters. These types of water filters can be used without electricity because water passes through much larger pores without any external pressure. Also, they do not hold back any water so there is no wastage of water. These filters are adequate to remove undissolved solids and larger impurities. However, they are not efficient in removing the TDS level. So, they are not recommended to use in case of very hard water.

3.    The ultraviolet purification system uses ultraviolet rays for the purification of water. A UV purifier throws high-intensity UV rays on the water which kills disease-causing bacteria and viruses. Most of the UV filters use some form of external sediment pre-filters to remove undissolved impurities and activated carbon to remove chlorine and other dissolved impurities.

4.    Gravity-Based Purifiers comprise of sediment and activated carbon filters which can remove large and un-dissolved impurities like mud and sand along with chemicals. These types of filters are easy to install and directly fitted on taps. They are useful when water does not have a higher concentration of chemicals and salt.

It is important to know the type of impurities and source of water at home before buying a water purification system. In doing so, the above-given information will help in making the right decision.
