Types of water purifier:

There are 3 different types of water purifiers

1.Electric Water purifier:

This type of water purifier works with help of electricity; it is used mostly in area where there is constant supply of water and electricity.

For the drinking water to make soft and suitable to drink this purifier purifies TDS, suspended impurities, contaminants and tend to kill micro organisms present in water.

  • RO water purifier: This is electric water purifier that uses reverse osmosis technology. The technology is used to remove solid particles, impurities and contaminants from water by passing water through semi- permeable membrane.

Compared to other purifiers these water purifiers are more expensive.

  • UV water purifier: UV purifier’s uses ultraviolet radiation which helps to kill micro organisms that causes diseases.

UV purifiers are suitable in areas where there is low TDS as they don’t remove solid particles from water. Compared to RO water purifier these purifiers are less expensive.

2. Non- Electric water purifier:

Non electric water purifier’s don’t need power they work without the use of power. They remove dissolved chemicals, virus, germs, suspended particles and impurities.

If your area don’t have continuous water and power supply then these purifiers are suitable, it comes in low budget.

  • UV water purifier:

UV water purifiers are non electric and uses gravity instead of power. They pass the water through semi permeable UF membrane which traps the viruses and germs that are present in water. Turbidity and mud of the water is also removed from water.

This purifier is incapable of removing dissolved solids and is suitable for areas where there water TDS is low.

  • Activated carbon water purifier:

Inorganic contaminants and heavy metals can be removed with the use of this non electric water filter this is called activated carbon water filter.

Physical absorption is used by the carbon filters to remove chemicals that give bad taste and odour to the water.

They provide safe and drinking water which can be stored in the storage tank by removing chlorine and disease causing pesticides.

  • Sediment Filter:

Sediment filters are sealed in plastic container and are shaped cylindrically this removes sediments present in water like rust, mud, sand and other impurities.

3. Gravity- Based water purifier:

Gravity based filters does not uses electricity to work. In the areas where there is power scarcity. With the help of gravity the water gets filtered as the water flows from top to the bottom without the help of any force.

We obtain safe drinking water as they uses micro fiber mesh, activated carbon, UF which absorbs dirt, impurities and small carbon granules from water.

  • Gravity- based candle filter purifier:

Gravity-based candle filter purifiers use ceramic candle filters made of clay contains small pores helps to purify the water. These purifiers divided into two parts upper part where we pour water which will pass through the candles, this will absorb impurities in water. Lower part stores the pure water ready to drink.

These filters are easy to use and cheap. They are very useful in removing impurities like iron, viruses. They also improve water taste and smell. The purification rate is not so high.

In some cases, to purify the water more than two candles to be used. We suggest to boil the filtered water before drinking this will be more safe.

  • Gravity-based filters with chemical capsules:

These types of filters are also called as chemical based gravity filters. To remove suspended particles from water, the water is passed through a micro fiber mesh. To kill the various diseases causing micro organism and bacteria chemical chlorine is used.

If the chlorine quantity is more, it is harmful to human health so water is made to pass through the activated carbon filter to remove chlorine.

These filters are easy to use but have high maintenance cost as the chemical batteries and carbon filters need to be changed at regular intervals.

Without the use of power chemical carbon filters is successful in removal of bacteria, virus, suspended particles, turbidity.

Working of UV water purifier:

This is one of best process of water purification systems; the technology is highly capable to kill many germs, bacteria, micro- organisms and viruses.

In this UV water purification process it mainly attacks the core or DNA of micro organism as they lead to cause diseases like flu, typhoid etc. The UV lamp kills the diseases caused due to presence of micro- organisms.

Working process of UV purifier is it allows the water to flow through tube inside water purifier that have external UV lamp. A UV ray kills the bacteria and treats the water, as there is no outlet pipe, the dead bodies can’t be removed from water.
