Buying Guide For AO Smith Water Purifiers

Earth is submerged 3/4th of its part in water but, the freshwater to drink depends on glaciers and groundwater. The water is everywhere, but very few left to drink. Scientists are searching for life on Mars to search where water is existing. Therefore, water holds an essential part of human existence.

But the question arises, do we have access to clean and pure water to drink?

The answer lies in our present scenario. We as humans have to take necessary steps to conserve mother nature. The release of human and industrial waste is the primary cause of water pollution.

So, how we will drink pure water? We have a solution for that, you can invest your money on water purifier to eliminate the impurities.

Let us understand the various Sources Of Water Pollution

When glaciers melt, it flows in the form of a river and provides fresh and clean water. On the way of the river journey, it passes through plains and plateaus, and gather salts and minerals from the rocks and sands.

The salts consist of Potassium, Sodium, Chloride, and Magnesium along with phosphates and nitrates. The form is known as TDS. You will understand what is TDS as we proceed in our buying guide.

The impurities consist of pollutants that pollutes river water. These pollutants are human waste like sewage and other harmful impurities. Industries are responsible for polluting the river through its chemicals such as arsenic, lead, iron, and mercury.

When these impurities combine causes an increase in water-borne diseases like cholera, dysentery, etc.

We will understand the various methods of purification based on the level of impurities and TDS in water.

Types Of Impurities

There are salts contaminated in water that causes water-borne diseases. As you move to coastal regions the water salinity increases in the groundwater. The borewells and dug wells are the primary sources of water in such areas that do not have a riverbank.

Any source of water needs purification as it contains impurities like microorganisms, animal matter, and addition TDS.

Chlorination is a process that is common in towns and cities area, where water is treated to remove chlorine.

Eradicating these wastes requires the use of modern technology like Reverse Osmosis (RO), Ultraviolet Purification (UV), and Ultra-Filtration (UF). There are some models of water purifiers that employs all the above methods.

1. Tds Level

Total Dissolved Solids are the total amount of mobile charged ions, including minerals, salts or metals dissolved in water. They are necessary for human body but requires in a balanced way.

The list of acceptable TDS levels are as follows:

  • Below 300 – Excellent
  • In the range of 300 to 600 – Fine for human consumption
  • 900>TDS>600 – Fair and acceptable
  • Between 900 and 1200 – Poor level of TDS
  • Above 1200 – Not safe for drinking

Mostly you will find the groundwater TDS more than 900, which is not fine for human consumption.

The water TDS level maybe 300. But the water can have a high concentration of arsenic and mercury and the lower concentration of other salts.

In this scenario, it becomes necessary to eliminate water impurities and maintain the water balance.

If you want to buy a water purifier then this article is for you. When you go out to buy the water purifier, you look for advanced technologies purifying system that gives surety of purification.

It is better to find the best at a nominal cost, and there are some aspects of the purifying system that you must know.

The water purifies in different technologies. The technologies are RO (Reverse Osmosis), UV (Ultraviolet Filter), UF (Ultra-Filtration), and SCMT (Silver Charged Membrane Technology).

Let us under these types in details:

2. Water Purification Technology

There is some popular water purification technology. We will focus only on the popular ones, those are:

  • RO Filters: This filtration process involves the water passing through the semipermeable membrane that traps chemical, and soluble impurities like arsenic, lead, mercury, and pesticide residues. The membrane also filters bacteria, viruses, and microorganisms. When you use this filter, you eliminate TDS up to 90%. The RO water filters work on a 5 or 8 stage purification depending on the configuration of the water purifier.
  • The Sediment Filter:This filter helps to eliminate the entry of large particle impurities. This filter is fitted outside the machine. You have to use the sediment filter only when you find the water is impure, especially the water treatment by the municipalities before distribution to societies and colonies.
  • Pre-Activated Carbon Filters: The pre-activated carbon filters remove the organic impurities that give bad smell and color to the water.
  • RO Mechanism: The science behind Reverse Osmosis is that the water transfers from a higher concentration to lower concentration when passing through a semi-permeable membrane. Hence, you need to have a water pump that helps you to push water through the RO membrane. RO membrane kills impurities of all kinds in the water. Here the water separates in two-part, the pure water filters and impure drains out.Then, the pure water passes through the UV chamber for the next level filtration.
  • Ultraviolent Protection: The pure water after the RO filtration stage contains bacteria and viruses. The RO filtration cannot filter impurities with a molecular weight of less than 20. Hence, this water now passes through the UV chamber where the Ultraviolet radiation that kills microorganisms and bacteria makes the water safe to drink.
  • Ultrafiltration: The purest form of water goes through the Ultrafiltration membrane to remove traces of residual impurities and clears that.
  • The Post-Activated Carbon Filter: It removes the volatile organic compounds that improve the taste of water.
  • The Mineralizer: The mineralizer adds essential minerals that were eliminated in the RO purification process. Thus, the replenishment enhances the good content of purified water.

Benefits Of Water Purifier

  •  You get purified water to drink that will keep away the water-borne diseases.
  • Get Cold or Warm water: It happens when you have a small baby at home, they need proper care, and usually, they drink warm water. The purifier saves your time and effort.
  •  Added water and minerals that enhance the taste and odor of water.
  •  Removal of soluble impurities with six-stage water purification.
  • Makes you feel healthy.

Drawbacks Of Water Purifier

  • The Water Purifier wastes a lot of water as more than 50% of water drains out of the raw water. This huge amount of wastage can be threatening for our sustainable development future.
  • Find alternatives for reusing the wastewater for cleaning purposes and planting water.

Frequently Asked Questions

1.How does the Reverse Osmosis work?

The Reverse Osmosis comes with a semi-permeable membrane that allows only pure water to pass. The membrane eliminates the contaminants that are too large to pass through the small pores. Thus, the purification process removes larger and harmful particles.

2.How to conserve the rejected water?

RO water purifier eliminates 80 % impure water that drains out. While many water purifiers save more than 50 % of water as purified. You can also keep the rejected water stored separately in a bucket and later use it for car washing or watering to the plants.

3.How much is the maintenance cost of RO water purifiers?

The maintenance of any machine is necessary for efficient working. When your RO filter, you can use it for a year or so without changing the filter if your area water has low TDS. But if the water TDS is high, then you have to keep water filter changing in 6 months duration.

4.Does the RO water purifier enhance the taste?

During the RO filtration, it removes the essential minerals from water and makes it taste bland. Most of the company has a water purifier with MIN-TECH that adds essential minerals and makes the water taste better.
