Water quality safety is closely related to health. As people's requirements for drinking water quality increase, various water purification devices emerge in an endless stream. Among them, the 8-stage filtration water purification device has attracted widespread attention due to its multi-level filtration and efficient purification functions.
So, what is an 8-stage filtration water purification device? How does it work and what advantages does it have? This article will explore this topic in depth to help readers fully understand the functions and characteristics of the 8-stage filtration water purification device.
What is an 8-stage filtration water purification device?
As the name suggests, the 8-stage filtration water purification device refers to a water purification device that uses 8 different filtration levels to purify water layer by layer. This type of equipment usually combines a variety of filtration technologies, including mechanical filtration, adsorption filtration, ion exchange, and ultraviolet sterilization, to ensure the purity and safety of water quality. Each level of filtration has its specific function, and under the joint action, it can effectively remove impurities, chemical pollutants, harmful microorganisms, and odors in the water, providing high-quality drinking water.
The concept of multi-stage filtration
In water purification equipment, "multi-stage filtration" refers to the process of gradual purification of water when it passes through multiple filter elements or filter materials. Each level of filtration treats different types of pollutants to ensure the cleanliness of the final water. The 8-stage filtration water purification equipment is an advanced form of this multi-stage filtration system, which improves water quality through 8 different filtration procedures.
What are the components of the 8-stage filtration water purification equipment?
The filter element structure of the 8-stage filtration water purification equipment usually includes the following common filtration steps:
● Level 1: Primary filter
The primary filter is usually made of stainless steel or nylon and is used to intercept larger particles, such as silt, rust, suspended matter, etc. This is the first barrier to purify water and can effectively reduce the burden of subsequent filter elements.
● Level 2: PP cotton filter element
The PP cotton filter element has a high filtration accuracy and can usually remove suspended particles above 5 microns, such as colloids, suspended silt, etc. It further purifies the water quality to ensure that there are no large particles of pollutants in the water.
● Level 3: Activated carbon filter element
The activated carbon filter element is mainly used to absorb odor, discoloration and organic matter in water, such as chlorine, pesticide residues, heavy metals, etc. It can improve the taste of water and remove chemicals that are harmful to the human body.
● Level 4: Granular activated carbon filter element
Unlike the third-level activated carbon, the granular activated carbon filter element has a larger surface area, which can further adsorb dissolved gases, organic compounds and trace elements in the water, and enhance the water purification effect.
● Level 5: Precision filter element
Precision filter elements are usually composed of ultrafiltration membranes or microfiltration membranes, which can filter out bacteria, viruses, colloids and other microorganisms to ensure the hygiene and safety of water. The filtration accuracy can reach 0.01 microns, which greatly improves the safety of water quality.
● Level 6: Reverse osmosis membrane
The reverse osmosis membrane is one of the core components of water purification equipment, which can filter out salt, heavy metal ions and other soluble solids in water. The reverse osmosis membrane has extremely high filtration accuracy and can remove more than 99% of impurities to provide the purest water.
● Level 7: Mineralized filter element
The water quality after the first six levels of filtration is pure but lacks minerals. Therefore, the mineralized filter element can add an appropriate amount of minerals and trace elements to improve the nutritional value of the water quality and ensure that the water quality is healthier.
● Level 8: UV sterilizer
The UV sterilizer uses ultraviolet rays to irradiate the water flow to kill bacteria, viruses and other pathogenic microorganisms in the water. This step ensures the hygiene of the water and prevents secondary contamination of microorganisms.
What is the working principle of the 8-stage filtration water purification equipment?
The working principle of the 8-stage filtration water purification equipment is based on the layer-by-layer purification of water. Each layer of the filter device treats different types of pollutants and finally produces high-quality drinking water. Its workflow is as follows:
1. Water inlet: The water first passes through the primary filter to intercept larger particulate matter, such as sand, rust, etc., to avoid clogging subsequent filter elements.
2. Preliminary purification: The water flow after the primary filter enters the PP cotton filter element to further remove fine suspended matter and colloidal particles and improve the turbidity of the water.
3. Adsorption filtration: The water enters the activated carbon filter element to adsorb organic pollutants, chlorine and odor in the water to ensure that the water tastes fresh.
4. Deep adsorption: The water continues to pass through the granular activated carbon filter element to remove finer organic matter and chemical residues to further purify the water quality.
5. Fine filtration: Water passes through a precision filter element to remove microorganisms such as bacteria and viruses to ensure the biological safety of water.
6. Reverse osmosis filtration: The reverse osmosis membrane is used as the core filtration step to remove dissolved solids and heavy metals in the water and provide pure water quality.
7. Mineralization treatment: In the final stage of water purification, the mineralization filter element adds necessary minerals to enhance the nutritional value of water.
8. Sterilization: The ultraviolet sterilizer kills residual microorganisms in the water to prevent secondary pollution and ensure the hygienic safety of water during storage and use.
What are the advantages of 8-stage filtration water purification equipment?
The multi-stage filtration design ensures the multi-level purification of water quality. From large particles to trace chemicals, from bacteria and viruses to odors and colors, the 8-stage filtration equipment can effectively remove most of the pollutants in the water and provide drinking water close to pure water quality. Through the mineralization filter element, the 8-stage filtration water purification equipment can not only remove harmful substances, but also add an appropriate amount of minerals and trace elements that are beneficial to the human body while purifying, ensuring that the water quality is more suitable for human drinking.
Secondly, the application of ultraviolet sterilizer in the last step ensures the microbial safety of water quality. For occasions where highly purified water quality is required, such as hospitals, laboratories or household drinking water, 8-level filtration water purification equipment can provide all-round safety protection. 8-level filtration water purification equipment can deal with various water quality problems, whether it is residual chlorine and impurities in municipal water supply or heavy metals and minerals in groundwater, the equipment can efficiently handle them. Therefore, 8-level filtration water purification equipment is suitable for a variety of environments such as homes, offices, hospitals, and laboratories.
Although the equipment involves multiple filtration levels, a modular filter element replacement system is usually designed to make daily maintenance simple. The filter element has a long life and relatively low replacement cost, which further reduces the cost of use.
What are the application scenarios of 8-level filtration water purification equipment?
8-level filtration water purification equipment is suitable for a variety of scenarios due to its efficient purification function and multi-level safety protection:
