Choosing the best water filtration system can get a little difficult these days. Because our environment is increasingly polluted, various bacteria, heavy metals, and chemicals have penetrated the water. Therefore, the emergence of water purifiers is to help reduce harmful substances in the water and make the water cleaner. However, there are various types of water purifiers. Which one should we choose?
What are the four most common water filtration systems?
When choosing a water filtration system, reverse osmosis (RO) filtration technology is often considered the most efficient. The following are the characteristics and differences of different filter technologies:
1. PP cotton filter element filtration: This filter element is made of non-toxic and odorless polyester fiber particles. It is small, high in precision, and easy to replace. It is suitable for filtering strong acids, strong alkalis, and organic solvents, can remove a large amount of particulate matter in water, and has a large dirt-holding capacity.
2. Activated carbon filtration: Activated carbon filter elements are made of charcoal, bamboo charcoal, fruit shells, or high-quality coal. They have physical and chemical adsorption capabilities and can effectively remove impurities and odors in water.
3. Reverse osmosis membrane filtration: The reverse osmosis membrane can intercept all dissolved salts and organic matter with a molecular weight greater than 100. and the filtration accuracy is extremely high. The membrane's desalination rate can reach 98%, effectively preventing scale formation.
What is the best water filtration system?
ITEHIL is a portable electric filter with a more advanced water filtration system that uses an RO membrane for filtration. The filter pores of the RO membrane are at the nanometer level (0.1 nanometers) smaller than ordinary filter membranes (10-100 nanometers), and most diameters of viruses are 10-300 nanometers, so ITEHIL can truly filter more than 99.999% of viruses. Compared with ultrafiltration or nanofiltration filters on the market, RO membrane has a stronger filtration effect and can filter most water-soluble substances, such as soapy water, coffee, heavy metals, organic pollutants, scale, fluoride, bacteria, etc. Go to the ITHIIL Portable Water Filtration System product page for specific details.
Multi-layer filtration of ITEHIL water filtration system
1. Reverse osmosis filtration
It is currently the core technology for producing pure water in the world. Its core component is a reverse osmosis membrane with a pore diameter as fine as 0.0001 microns. Under certain pressure, only water molecules can pass through the reverse osmosis membrane, while the inorganic salts and Impurities such as heavy metal ions, organic matter, colloids, bacteria, and viruses cannot pass through the reverse osmosis membrane because their diameters are greater than 0.02 microns, so the water filtered by the reverse osmosis membrane is purer.
2. Nanofiltration
The filtration precision of nanofiltration is between ultrafiltration and reverse osmosis. It can intercept nano-scale (0.001 micron) substances and has a lower salt rejection rate than reverse osmosis. It is a membrane separation technology that requires power and pressure. Nanofiltration membrane can For substances with a molecular weight cut-off of several hundred, the rejection rate for certain low-molecular organic compounds can reach 90%. Because nanofiltration is highly efficient at removing natural organic matter from water, it can also appropriately retain low molecular weight inorganic components.
3. Ultrafiltration
Ultrafiltration has a filtration accuracy of 0.01 to 0.1 microns. It is a membrane separation technology that utilizes pressure difference. It can filter out rust, sediment, suspended solids, colloids, bacteria, viruses, macromolecular organic matter, and other harmful substances in the water, and retain it. Some mineral elements that are beneficial to the human body. It is a core component in the production process of mineral water and mountain spring water. The water recovery rate in the ultrafiltration process is as high as more than 95%. It can easily achieve flushing and backwashing, is not easy to block, and has a relatively long service life. However, heavy metals, pesticide residues, etc. cannot be filtered out, so ultrafiltration can only be regarded as rough filtration and the purification is not complete.
4. Activated carbon filtration
Due to its porosity, activated carbon can absorb fine substances in various liquids during filtration. It is often used in water treatment for decolorization, deodorization, dechlorination, removal of organic matter and heavy metals, and removal of synthetic detergents, bacteria, viruses, radioactive and other pollutants.
5. Microfiltration
Microfiltration technology is the most widely used, but its accuracy is not high. It is generally used as a pre-treatment for water purifiers. The filtration accuracy of microfiltration is generally between 0.1 and 30 microns. Common PP filters, activated carbon filters, ceramic filters, etc. all belong to the category of microfiltration. They are used for simple coarse filtration and can remove large particle impurities such as sediment and rust in the water. , but it cannot remove bacteria, viruses, organic matter, heavy metal ions, and other harmful substances in the water.
Water purifiers with different purification technologies have their own applicable scopes. When selecting a water purifier, you should fully consider the characteristics of various purification technologies based on the water quality and usage habits, and equip yourself with products that suit your needs.
How to choose a quality water filtration system
First, we need to clarify what kind of water needs to be filtered. Typically, water needs to be filtered in the following situations:
1. The water source is not clean. For example, water obtained directly from natural water sources such as rivers and lakes may contain impurities such as sediment, algae, and microorganisms and needs to be filtered.
2. Poor water quality. For example, hard water, water with excessive chlorine content, etc., needs to be filtered and purified.
3. Water with a peculiar smell, color, or smell needs to be filtered and treated.
Next, we need to understand how to filter water. There are many ways to filter water, the most common of which is using a water filter. Water filters usually consist of multiple filter elements, each with different filtration effects. For example, activated carbon filters can remove odors and chlorine, while ultrafiltration membrane filters or reverse osmosis membrane filters can remove smaller impurities and bacteria.
When choosing a water filter, we need to consider the following factors:
1. Filtration effect: Choose a water filter that can remove impurities and harmful substances from the water.
2. Brand reputation: Choose well-known brands to ensure the reliability of quality and service.
3. Frequency of filter element replacement: The filter element of the water filter needs to be replaced regularly. Choosing a filter element that is easy to replace can save time and energy.
4. Price: Different brands and models of water filters have different prices, so you need to choose according to your own needs and budget.
To sum up, choosing a high-quality water filtration system requires consideration from many aspects. Currently, the RO reverse osmosis membrane water filtration system is the best water filtration system. The ITEHIL portable water filtration system uses PP cotton + activated carbon. +RO reverse osmosis membrane filtration, electric self-priming pump, faster filtration efficiency, portable design, can be used anytime, anywhere, outdoors, at home, or in emergencies, ITHIIL brand is worth having.
