How the water filter bag works？
Working principle
The multi-bag filter introduces the water to be filtered into the filter shell through the pump, and the water enters the filter bag. Under the action of pressure, the water passes through the microhole of the filter bag, and the impurities are trapped in the filter bag, so as to achieve the filtration and purification of water.
Component introduction
Filter bag: Made of polypropylene, with different micron grades, such as 0.2 micron, 5 micron, 10 micron, 100 micron, can be selected according to filtration needs. The lower the micron number, the finer the particles that can be filtered out, and the higher the filtration accuracy.
Multi-bag filter: usually made of corrosion-resistant materials such as stainless steel, it can accommodate multiple filter bags to increase the filtration area and flow rate and improve filtration efficiency.
Material property
Polypropylene (PP) : good chemical stability, acid, alkali, organic solvent resistance; With good mechanical strength and wear resistance, the price is relatively low, cost-effective.

What is a water filter bag?
A water filter bag is a filtration device mainly used to remove impurities, suspended solids and other substances in water to purify water quality. The following is a detailed introduction:
Structure and Material
- Structure: Generally, a water filter bag is a bag-shaped structure with an opening at one end. The opening is usually designed with a ring or other fixing device for easy installation and connection to the water filtration system.
- Materials: It is often made of various filter materials such as polyester, polypropylene and nylon. These materials have different filtration precisions and chemical resistances to meet different filtration requirements. For example, polyester filter bags have good strength and chemical stability, while polypropylene filter bags are known for their excellent acid and alkali resistance.
Working Principle
- The water to be filtered enters the filter bag through the inlet. As the water passes through the filter material of the bag, impurities, suspended solids, and particulate matter in the water are trapped by the filter material due to the sieving and adsorption effects. The filtered water then passes through the filter bag and flows out through the outlet, thus achieving the purpose of water purification. The filtration precision of the filter bag can range from a few microns to hundreds of microns, depending on the specific application and the fineness of the filter material.
Applications
- Industrial Fields: In industrial water treatment, such as in the chemical, electroplating, and pharmaceutical industries, water filter bags are used to remove impurities in process water to ensure the quality of products and the normal operation of production equipment. They can also be used in industrial wastewater treatment to reduce the content of pollutants in the wastewater before it is discharged.
- Domestic Use: In household water purification systems, water filter bags are often used as the first stage of filtration to remove large particles of impurities, rust, and sediment in tap water, prolonging the service life of subsequent water purification equipment such as water purifiers and improving the quality of domestic water.
- Aquaculture: In aquaculture, water filter bags are used to filter pond water or circulating water in aquaculture systems to remove uneaten feed, fish feces and other impurities, maintaining good water quality and a suitable living environment for aquatic organisms.
- Swimming Pools: In swimming pool water treatment systems, water filter bags play a role in filtering out suspended matter, leaves and other impurities in the water to keep the pool water clean and clear and reduce the burden of disinfection and purification equipment.

Industrial Dust Removal Filter Bag P84 Material with Glass Fiber PTFE Pocket Filter Industrial Dust Filter Bag
Industrial Dust Removal Filter Bag
It is made of P84 material and is equipped with a glass fiber PTFE pocket filter. This is an industrial dust filter bag.Detailed Description
Overall Overview
This is an industrial dust removal filter bag that plays a crucial and indispensable role in industrial production scenarios where a large amount of dust is generated, such as cement plants, steel mills, power plants, waste incineration plants, etc. It can effectively capture and filter dust, ensuring that the discharged gas meets environmental protection standards. Meanwhile, it also helps protect production equipment and the working environment.Material Aspects- P84 Material: P84 fiber is a high-performance synthetic fiber with excellent high-temperature resistance. It can generally be used continuously at a high temperature of 260°C, and it can even withstand higher temperatures instantaneously. It also has outstanding chemical stability and can resist the erosion of a variety of chemical substances, showing good tolerance to corrosive gases and liquids such as acids and alkalis. Moreover, P84 fiber has a high filtration efficiency, which can effectively intercept and capture dust particles of various particle sizes, providing a reliable guarantee for industrial dust removal.
- Glass Fiber: Glass fiber features high strength and high modulus, which can enhance the overall mechanical properties of the filter bag, making it more robust and durable, and less prone to damage. At the same time, glass fiber also has a certain degree of high-temperature resistance. When used in combination with P84 material, it further improves the stability and reliability of the filter bag in high-temperature environments.
- PTFE: Polytetrafluoroethylene (PTFE) has an extremely low surface energy, which makes it difficult for dust to adhere to the surface of the filter bag. The dust can be easily removed by the dust cleaning system, thus ensuring the filtration performance and service life of the filter bag. PTFE also has excellent chemical stability and weather resistance, and can maintain stable performance in various harsh industrial environments.
Structural Features- Bag Filter: It adopts a bag structure, which has a large filtration area and can handle a large amount of dusty gas per unit time. The filter bag is usually cylindrical or oval in shape, with one end closed and the other end open. The open end is connected to the pipeline or box of the dust removal equipment. The dusty gas enters the filter bag from the open end. After being filtered by the filter material, the dust is intercepted on the inner surface of the filter bag, and the purified gas is discharged through the pores of the filter bag.
- Pocket Filter (Bag-in-bag Structure): The so-called bag-in-bag structure means that some small bag-shaped structures are set inside the large filter bag. These small bags can further increase the filtration area and improve the filtration efficiency. At the same time, the design of the small bags can also make the distribution of dust more uniform during the filtration process, reduce the accumulation of dust in local areas, and improve the overall performance of the filter bag.
In general, this industrial dust removal filter bag can play an efficient and stable filtering role in the field of industrial dust removal, providing strong support for the environmental protection and sustainable development of industrial production. -
Working Principles of Dust Collection Equipment Filter Bags
Dust collection equipment filter bags operate through the combined action of multiple principles to achieve efficient purification of dusty gases:1. Sieving Effect
The filter bag functions like a sieve with a specific pore size. When dusty gas passes through, dust particles larger than the pore size of the filter bag cannot penetrate and are directly intercepted on the surface of the filter bag. For example, in some wood – processing workshops, large wood chips are intercepted by sieving.
2. Inertial Impaction
When the dusty gas stream passes through the filter bag, the direction of the gas flow changes. Larger – mass dust particles, due to inertia, cannot change direction in time along with the gas flow and will collide with the fibers of the filter bag and be captured. In steel mills, during the high – temperature smelting process, large – sized dust particles are intercepted by inertial impaction when the gas passes through the filter bag.3. Interception Effect
Some dust particles slightly smaller than the pore size of the filter bag, when brought close to the filter bag fibers by the gas flow, will be directly intercepted by the fibers. It’s similar to how small objects in a narrow passage are easily blocked by obstacles beside them.4. Diffusion Effect
For extremely fine dust particles, they will perform irregular Brownian motion under the influence of the thermal motion of gas molecules, which increases the chance of contacting and being adsorbed by the filter bag fibers. In chemical production, some fine dust is captured by the filter bag through the diffusion effect.5. Electrostatic Adsorption
Some filter bag materials generate static electricity during friction with dust, or they already carry static electricity. Dust particles will be adsorbed onto the filter bag due to electrostatic attraction, enhancing the filtration effect. For example, some filter bags specially used to handle flammable dust often utilize the principle of electrostatic adsorption to improve dust removal efficiency.These principles work in concert, enabling the filter bags of dust collection equipment to effectively purify dusty gases, ensuring a clean production environment and the normal operation of equipment. -

Polyester needle felt waterproof, oil-proof and electrostatic filter bag.
Our company polyester needle filter felt selection of 1-2.5D polyester fine denier, with high strength and low elongation yarn woven reinforced base cloth, through the needle reinforcement and post-treatment technology. In addition to the characteristics of high porosity, good permeability, acid resistance and moderate alkalinity of ordinary felt filters, the product has very good wear resistance, so it is a variety of felt filters widely used. G weight from 350g/m2-800g/m2, thickness from 1mm-4mm our factory can produce. The post-treatment methods are calendering, singeing, heat setting, impregnation drying, coating and so on. It has the characteristics of stable size, easy cleaning and long service life.The surface smoothness of filter material has a great influence on the dynamic running resistance of filter material. The initial resistance of the filter material is determined by the permeability of the filter material itself, and the resistance in operation is many times larger than the initial resistance. The running resistance depends on the smoothness of the filter surface and the cleaning effect. It is generally hoped that when the filter material ensures the same filtration efficiency, the larger the air permeability, the better, that is, the lower the resistance, the better, because this can save a lot of energy. In the dust collector with air flow back blowing, when the air flow of the same pressure and the same air volume is used for dust removal, the dust removal effect of the woven fabric with high air permeability is better than that of the woven fabric with low air permeability. Therefore, in the case of ensuring the high filtration accuracy of the filter material, how to improve the permeability of the filter material and improve the surface smoothness, reduce dust adhesion, and reduce the operating resistance is the first topic that the filter material manufacturer should study. The air permeability of the surface resinized smooth finishing needled filter felt developed by our factory is more than 50% higher than that of ordinary calender finishing filter material, and the surface smoothness is more smooth than that of calender finishing.
