It is well known that water can contain sediments, chemicals and many other types of impurities that not only affect the taste and smell of water, but can also affect the health of the consumer and everyone around him.
This is when the idea of installing a water filtration system can appear as a priority to provide you with clean and healthy drinking water. Once you have water with better taste and smell, you will find yourself drinking more.
What is a water purification system?
It is the process through which unwanted chemical compounds, organic and inorganic materials and biological contaminants are removed and processed.
Said process also includes the so-called distillation (it is the conversion of a liquid into vapor so as to condense it again in liquid form) and on the other hand it also inserts the deionization process (this consists in the elimination of ions through the extraction of salts dissolved).
Purifying water has as its main purpose to provide much cleaner drinking water. This process also meets the needs of medical, pharmacological, chemical and also industrial applications for clean and potable water. With the water purification process, the concentration of pollutants such as particles in suspension, bacteria, viruses, fungi, parasites and fungi is reduced.
Water purification process
Most of the water used in industrialized countries is treated and processed in water treatment plants. It is known that the methods used by these plants in pretreatment depend on their size and also on the severity of the contamination. These practices have been standardized in order to guarantee general compliance with national and international regulations.
Then most of the water is purified after being pumped from what is its natural source or also directed through pipes to holding tanks. Once the water is transported to a central location, then the purification process begins there.
Water purification pretreatment
In what is called pretreatment all biological contaminants and other materials are removed from the water.
First the screening is carried out, which is responsible for eliminating large waste, such as sticks and garbage. This pre-treatment may include the addition of chemicals to control the growth of bacteria in pipes and tanks as well as a stage that incorporates sand filtration.
The preconditioning is the part of the process in which water containing minerals (also called hard water) is treated with sodium carbonate, although this is also part of the pretreatment process. With regard to this treatment, sodium carbonate is added to the water in order to expel the calcium carbonate, which is one of the main components in the shells of marine life and is also an active ingredient in agricultural lime. With this step of the water purification process, it is possible to guarantee that the hard water, which leaves mineral deposits that can clog the pipes, can be modified to achieve the same consistency as the soft water.
Now it is the turn of the prechlorination process, here chlorine is applied to raw water which can contain high concentrations of natural organic matter. This organic matter manages to react with chlorine during the disinfection process and can lead to the formation of disinfection byproducts.
Water purification and health
Using a high quality water filtration system will be an excellent decision and solution that will benefit you and your family, protecting them from harmful water contaminants. A professional purification system will ensure that the water delivered to your home is free of contaminants.
A filtration system will also limit your exposure to harmful chemicals, save money, and even protect the environment.
Water purification methods
Between the water purification methods available in the market we can find.
- Chemical cleaning: With this type of water purification chemicals are added (such as ammonia, lime, hydrochloric acid, sulfuric acid and soda). In this type of method the polluting substances react through their dilution with the chemical substances. It is used to remove heavy metals from the water, as well as their disinfection and also discoloration. This method eliminates insoluble impurities by 95%.
- Biological cleaning: This type of purification method is usually the second step of what would be the mechanical treatment that we will explain next.
The biological treatment is based on the self-purification of natural bodies of water. Normally the microorganisms that live in these bodies of water, most of the bacteria, feed on the organic waste and then mineralize it; this reduces the level of contamination of the wastewater. To make this type of cleaning, aeration tanks are used, which are tanks with an increasing number of bacteria.
- Mechanical cleaning: Named above, this is the most commonly used treatment, it is very common and is used in municipal water treatment plants. Here the use of different filtering elements that eliminate water contamination, such as sand, slag, sludge, broken glass, etc., is applied.
With this treatment you can find approximately 70% of the impurities in the wastewater and in turn eliminate them. This type of mechanical cleaning is used for water purification in homes and also in apartments; the filter is also installed at the entrance of the entire water supply system.
- Physico-chemical treatment: with this kind of water purification water method, the treatment is made through the use of coagulation, oxidation, flocculation, electrolysis, evaporation and others. If we compared the biological treatment with this we will find some common features: a high-quality cleaning and of course, the removal of toxic organic contaminants. This method is highly recommended because is used for removal of deferred organic and inorganic substances and in some cases soluble gases.
Water purification technology
- RO purification: RO means reverse osmosis; this purification technology is the most used. RO makes use of membrane technology that is responsible for removing dissolved salts, impurities and, of course, germs from water. The semipermeable membrane will separate the germs from the water, retaining them.
- UF purification: This is the Ultra Filtration method, which uses membranes similar to the RO membranes but in this case, the pores of said membrane are larger. These eliminate all the colloidal particles, in which we include most of the pathogenic organisms and also the turbidity, nevertheless they do not eliminate the solids nor dissolved salts.
- Activated carbon filter purifier: This type of water purification method is based on the use of activated carbon filters to carry out the purification process.
In the carbon filters, the elimination of chemicals such as chlorine, pesticides and also impurities can be carried out to a large extent. This type of filtration changes the taste and smell of the water, but does not require electricity for its operation.
In search of the evolution and improvement to be able to comply with the strict environmental regulations and of course wanting to satisfy the increasing water demand of the growing populations, several water treatment plants have been in charge of using intelligent technologies to increase the reliability in your operations. Now there is a great demand for the use of sophisticated technologies, since water treatment processes have incorporated complex instruments and also control systems for these processes.
Water purification systems are varied and differ from each other; however they seek the same objective, so it is best to choose the one that best suits your needs and possibilities.
