We are increasingly aware of the quality of the water we consume and more demanding with its composition characteristics. Water filtration and purification are presented as two interesting solutions for those who requiren the highest guarantees of health. Science and technology have advanced significantly in everything related to obtaining a product free of solid particles (filtered) and substances that, depending on their concentration level, could pose a risk to health (purified).
But, what types of water filters exist?
Activated carbon filters
Activated carbon works as a granular filter media to remove organic compounds that are considered undesirable in drinking water. They separate chlorine, herbicides and other elements from water before drinking it, without strange odors or flavors.
Some of the important aspects that must be considered for an activated carbon filter to be efficient are:
Contact time required
The size of the filter containers
Filling and emptying facilities
Security measures
Water is one of the most valuable resources in the world. As the world's population grows, efficient water treatment will continue to grow as well. Heactivated carbon filter offers an effective solution in many water treatment applications, whether to ensure drinking water is safe for human consumption, to protect river bodies from the discharge of potentially contaminated effluent, or to help manufacture premium products.
Ultraviolet light
He UV purifier It is undoubtedly your best option for complete disinfection anywhere that requires purified, bacteria-free water and to prevent any other contamination of the water before it is drunk or used in any process. It is useful in almost any application where pure, safe, microbe-free water is required and where there is the possibility of the water becoming contaminated before it reaches the point of end use, whether the water used directly by your product or cleaning of equipment or products on the production line.
LUltraviolet light does not use chemical substances, therefore, this treatment has a greater scope. The use of this system is commonly used in the treatment of different industrial waters such as aquaculture, petrochemicals, marine or transportation. Because it does not use chemical products, it is especially recommended for industries whose processes do not allow the use of this type of substances.
Ultraviolet rays can be used in a wide range of flow rates. From large supplies to those that are smaller in size. It is valued as an ecological and safe system that can also be used in different types of fields. Apart from its application on wastewater, it can also be used for smaller purposes such as family-sized tanks.
Ultraviolet light is an optimal solution for different types of supplies. That is, it can be used on a wide range of supplies, from large to the smallest. This form of treatment stands out for its safety and environmentalism. It has applications for both industrial and other types of water. Therefore, it can be implemented in the treatment of water of different nature, from a family to a population.
Inverse osmosis
Reverse osmosis is a membrane technology that eliminates salinity from water. It is based on a diffusion process through a semipermeable membrane that facilitates the passage of dissolved gases and low molecular weight electrostatically charged molecules.
It is the system indicated for the production of pure water with a low salt content, free of viruses and chemical contaminants. Osmosis membranes are used, whose configuration varies depending on the nature of the water to be treated.
A reverse osmosis membrane is a semipermeable membrane that allows the passage of water molecules but not most dissolved salts, organics, bacteria and pyrogens. However, you must "push" the water through the reverse osmosis membrane by applying a pressure that is greater than the natural osmotic pressure to desalinate (demineralize or deionize) the water in the process, allowing pure water to pass through while retaining a most contaminants.
When pressure is applied to the concentrated solution, water molecules pass through the semipermeable membrane and contaminants are not allowed to pass.
Stages of the reverse osmosis process
Reverse osmosis is a water treatment process that removes contaminants from water by using pressure to force water molecules through a semipermeable membrane.
During this process, contaminants are filtered and removed. This allows you to leave drinkable, clean and delicious water. Reverse osmosis is capable of removing up to 99 percent of 65 different contaminants, including lead, fluoride, chlorine, and dissolved salts.
In a conventional reverse osmosis process, we find four stages:
Sediment Filtration
carbon filtration
Reverse osmosis membrane
refining filtration
