It is a known fact that due to the depletion of various layers in the atmosphere, there is direct contact of impurities with water. In order to have a healthy lifestyle, you need to drink pure water which is free from any sort of impurities. These impurities, that could be the amount of salt present in water or other particles, all contribute to making water unfit for drinking. That’s precisely why we need water purifiers in our lives. A water purifier is an apparatus that purifies the water and makes it fit for human consumption. It makes sure to wipe out only the impurities and leaves behind minerals and vitamins which are required by the human body.

Water Purifier: Water can be purified with filters and these filters trap the tiniest of impurities.

Distillation

In this method, water is purified by using an external heat source and as soon as it reaches the boiling point, it is then left to vaporize and that vapor is stored in a condenser and allowed to cool down. That is the purified water that we get.

Chlorination

In this method, chlorine is added to heated water and it kills all the germs and parasites available in the water.

Purification of water using a water purifier is the safest method to kill the germs and leaving the essential minerals and vitamins in the water. A water purifier has different filters fitted in them. All these filters have their own features and specifications. Read on to find out more about them.

Types Of Water Purifier: Variants

There are various types of water purifiers that you can install in your homes. Every water purifier has its own benefits and drawbacks. Here are the types of water purifiers in brief.

1. Reverse Osmosis (RO) Water Purifier

An RO water purifier uses a super porous membrane for purification of water. A pump is fitted in this type of water purifier which pushes the hard water through this membrane. It traps the solids in the membrane which are dissolved in water such as arsenic (As), fluoride (F), lead (Pb), chlorine (Cl), nitrates and sulfates. The purified water is then collected in a clean container which can be then used for drinking or cooking purposes. Only the RO water purifier has the ability to wipe out the metal particles from the hard water.

Variants Of RO Water Purifier

They are of 2 types based on where they can be fitted in your kitchen:

Wall mounted: This RO water purifier can be hanged on the wall or it can be placed on the top of a table or kitchen platform.

As soon as water passes through this membrane, the membrane traps the solids suspended in water, along with bacteria, and viruses. It is quite similar to the technology used in the RO water purifier, but the UF water purifier only purifies the large particles from the water while the RO water purifier can purify the tiniest of the impurities from the water. UF water purifier is perfect for places where the water has a low level of chemical impurities in it. Also, it doesn’t work well with hard water.

Some benefits and drawbacks of UF water purifier are:

  PROS   CONS

Water Purifier: Water Filters In Water Purifiers

1. Activated Carbon Filter

This water filter is used to cleanse the gases that are dissolved in water such as chlorine, nitrogen, ammonia, etc. It also cleanses the pesticides in the water bodies. It cleanses these impurities by absorbing them due to the porous nature of the carbon.

Water Purifier: Carbon filter is used to clean the gases dissolved in the water.

2. Biosand Filter

This water filter is simply layers of sand and gravel filled in a plastic or solid box and water is passed through these layers. The microorganisms in the biolayer eat all the impurities in the water and the pure water is then collected in a clean container for drinking purposes.

3. Reverse Osmosis

This is a type of filtration process where the water is made to pass through multiple stages of the active carbon filter and particle filtration. This water filter has very small holes through which the contaminated water passes and through this filter, only pure water comes out and the impure water is passed out through an outlet. The drawback of reverse osmosis is that sometimes it might remove the essential minerals and vitamins from the water which is required by the human body. Reverse osmosis also improves the taste of the water and it is the most commonly used method of water purification in households these days.

4. Ultra Violet Filter

This filter passes the UV rays through water which kills 99 % of the bacteria. But this process cannot filter the solid impurities present in water. It does not improve the taste of the water and also doesn’t remove the smell from the water. It can purify almost 2000 L of water each day.

5. Ceramic Filters

These water filters are just hollow cylinders made of clay and any volatile material. They have small size pores in them which wipes out chlorine and 99% of bacteria from the impure water.

6. Ion Exchange Resin Filter

Water is passed through the resins in these water filters which absorb the minerals resulting in the softening of water. They wipe out all the excess salts present in water and make it mineral free completely.

7. Sediment Filter

This is a type of filter that can be used with other water purifiers. Sediment is basically the impurities collected at the bottom of the water. It can be rust of metal pipes or sand or mud. They are made of cotton or polyester fibers. It comes in the shape of a roll and it is placed inside a sealed plastic container. It has the ability to wipe out dust, rust and mud particles from water. It also protects the UV and RO water purifiers from being damaged, increasing their lifespan.

Water Purifier: Why You Need To Use a Water Purifier?

The drink that gives you maximum energy and helps in keeping you healthy in the long run is water. But think how bad it could be for your health if you are not drinking pure water and instead, you are drinking water which has lots of impurities. Nowadays, the water that we get for drinking comes from different sources. These water sources are

  • Groundwater
  • Water obtained from rain, hail, snow or fog
  • Water obtained from biological sources such as plants
  • Seawater that is desalinated i.e. the excess salts and minerals are removed from seawater
  • Water obtained from storage facilities such as underground water pipes, reservoirs, water tanks or water towers
  • Water obtained from atmospheric water generator which extracts the water from the humid air

Water Purifier: How To Check If You Need a Water Purifier?

The water extracted from these water sources is not free of all the impurities. This water needs to be purified for consumption so that it doesn’t harm your health in any way. You can make sure by checking certain things of the water that is supplied to you whether you need a water purifier or not. To make sure the water is safe to drink you must check the following:

1. TDS (Total Dissolved Solids)

The water extracted from rivers, lakes or groundwater has an excess amount of calcium, magnesium, potassium, carbonates, sulfates, nitrates, fluorides, etc. you only need some amount of these salts in your drinking water. When you check the TDS of this water it will be high i.e. it will be more than 1200 mg/L.

TDS LEVEL (mg/L)  
300 excellent
300-600 good
600-900 fair
900-1200 poor
>1200 unacceptable

This data is according to the BIS standards, for reference: https://www.indiawaterportal.org/questions/frequently-asked-questions-faq-tds-total-dissolved-solids#Standards

If the TDS level of the water being supplied to you is between 300 and 900 mg/L then you don’t need a water purifier. If it is more than that then you must find a good RO water purifier.

2. PH Level

The PH level of the water is also checked to find out the level of impurities. The PH value of water indicates whether the water is hard or soft. Hard water is not suitable for drinking purposes.

PH OF WATER  
7 Pure water
<7 Acidic
>7 Basic

3. Dissolved Oxygen In Water

Oxygen mixes with the water because of diffusion which occurs in the atmosphere. 0 mg/L to 18 mg/L of oxygen in water is fine, but if it is more than that, you need to do something about it.

Water Purifier: If the water being supplied to you has some color then that water is impure water and it needs to be purified before drinking.

4. Color Of The Water

Water has no color. If the water being supplied to you has some color then that water is impure water and it needs to be purified before drinking.

5. Bacterial Growth

If there is bacterial growth in water, then that water is not at all suitable for drinking. It needs to be purified before drinking.
