Do you know all types of water filtration systems? Along with other devices, water filtration systems have the function of improving the quality of the water you drink and, in this market, there are several products. 

Firstly, it is vital that you understand that the domestic water you receive is treated by concessionary stations before reaching your home.

There are potability standards to be met, but it is not always possible to guarantee that the water coming out of the tap is safe.

This is because the water travels a long way from pipes, plumbing, and water tanks to fill your glass.

In this route, bacteria and microorganisms can pass that can transmit serious diseases to health.

Why are there different types of water filtration systems?

We understand then that the safest choice is to choose a water filtration system to maintain the best possible hydration and that’s why your water tastes sweet.

But, what are the differences between them? 

Water is a broad and complex topic and so are the types of water filtration systems. There are products that have a different filtration and purification system than others. 

There are also appliances that freeze the water and those that only offer natural temperatures. There are also products that are specific to a particular water source or point of use. 

With so many options, it is important to understand a little about the subject when choosing.

Know below the main types of water filtrations systems, their features, and benefits : 

Reverse osmosis system

The reverse osmosis system goes the opposite of everything water wants to do, that is, it forces clean water to pass through a membrane in the opposite direction to what it would naturally do.

As it passes, the membrane welcomes everything contained in it, bacteria, mineral salts, and organic and inorganic molecules. At the end of the process, you will have very pure water because the filters used for this type of purifier have such fine meshes that they are able to collect everything that makes the water not purified.

The reverse osmosis system is quite large and also more expensive than the other types. The only disadvantage of this plant is that during the passage the water loses most of its mineral salts. With this loss, you can have deficiencies in the body but fortunately, there are machines that allow you not to eliminate the right amount.

Countertop or wall water filtrations system

First, our specialty: is the water filtration system. To work, a water filtration system needs a water point: either attached to the faucet or plumbing. 

They have a pump capable of giving pressure to the water, which passes through the filter elements inside the refill (or chamber). When passing through the elements, impurities and residues unsuitable for our consumption are removed. 

Likewise, the chlorine present is reduced as it passes through the refill. The end result of the liquid is ideal: water without taste, color, or smell. 

The simplest models deliver:

  • Retention of chemical elements: such as chlorine and geosmin, removing flavors and odors.
  • Removal of suspended solids: such as clay, sand, algae, and other impurities;

Additionally, there are models with advanced technologies capable of retaining microbes, protozoa, and viruses. In these cases, the refill has the help of other filtration and purification systems. 

Of the existing types of water filtration systems, these (wall-mounted or countertop) have the great advantage of durability. It is important to remember that refill maintenance is necessary and that the change time is variable. Frequency of use, product type and brand, and the water quality in your region determine the right time to change the refill.

Ozone Water Filtration System

These products rely on the filtration method by means of ozonation. But in the end, how does it work? 

It captures ambient air, transports it to the water reservoir, and transforms oxygen into ozone. Ozone gas, in turn, has a high antiseptic, germicidal and oxidizing power.

Ozonated water is efficient in eliminating viruses and bacteria, as well as pesticide residues in food. Ozone can also play an important role in the oxygenation of the body.

This is because after eliminating impurities, it releases one of its molecules and returns to the oxygen state.

This is one of the safest types of water filtration systems. This is because, unlike chlorine, it does not produce chemicals that can cause unwanted reactions in our bodies.

Countries such as the United States, France, Germany, Switzerland, and the Netherlands have been using ozone in public water for almost 100 years.

Pressure Filter/Faucet

This type of filter is installed directly on the faucet or wall and has the most affordable price on the market. 

In principle, these filters generally use an activated carbon filtering system. Inside each product, there is a candle, composed of a cylindrical and porous element, capable of absorbing water impurities.

Installed directly on the tap or at the point of use, this filter traps particles in a physical as well as a chemical process. The active ions present in the candle help to eliminate unpleasant odors and tastes, as well as unwanted coloring in the water.

Central Filter

This model is also known as an inlet filter, as it is mainly installed in the hydraulic inlet, in the external area. It is a large-scale water treatment system.

Its function is to filter all the water in the place it serves. Therefore, it is essential to obtain healthy, potable or usable water in any type of installation.

It can be used in industries, shops, condominiums, residences, schools, hospitals, restaurants, etc. Installed at the supply inlet, it prevents all dirt from entering your water tank and passing through the entire pipe.

With a central filter, you keep out rust, sediment, clay, sand and other contaminating particles. This is one of the types of water purifiers that conserve the water tank and pipes and protect equipment that uses water.

Filter for Artesian Well

Finally, there is the artesian well filter, which makes important corrections to the water to make it drinkable. 

With the increasing pollution of groundwater sources, the need to correct chemical and physical compounds contained in water increases. 

This correction must be made with the artesian well filter, with the addition of chlorine for disinfection. The disinfection process can be done with the automatic chlorine doser, ultraviolet, or ozone system.

They are responsible for removing solid impurities, reducing turbidity, and color, and reducing excess iron and manganese. According to the quality of the water, the central filter can be a good indication of the case of an artesian well.

Types of Water Filtration Systems: Summary

Anyway, we could see that there is a type of purifier for every need. Shall we quickly resume what we covered in the text?

We have seen that it is possible to buy a filter at a more affordable price, such as a faucet/pressure filter. It offers water without particles, odor, taste, or unpleasant taste.

Countertop or wall water filtration systems are the most common on the market. Those with simple technology offer water free of impurities, without particles, and with reduced chlorine. Advanced technology models can provide protection against bacteria and viruses.

Ozone water filtration systems are able to capture oxygen and transform it into ozone. Ozonated water is efficient in eliminating viruses and bacteria, as well as pesticide residues in food.

The central filter is one of the most robust types of purifiers out there. It works at the water supply entrance and serves even condominiums, hotels, etc.

Among so many options and types of water filtration systems. it is important to remember to always look for certified products.
