bag filters for water treatment
Bag filters are commonly used filtration devices in the water treatment field. They intercept suspended solids, colloids, particulate impurities, etc., in water through built-in filter bags, featuring simple structure, high filtration efficiency, and convenient maintenance. Below is key information and application highlights:I. Core Components and Working Principle
1. Main Structure
- Filter Housing: Mostly made of stainless steel (e.g., 304/316L) or engineering plastics, pressure-resistant and corrosion-resistant, with inlet, outlet, and filter bag chamber.
- Filter Bag: Constructed from synthetic fibers like polypropylene (PP) or polyester (PET), with precision ranging from 1–500 microns, fixed inside the filter via a top ring.
- Support Basket: Secures the filter bag to prevent deformation during filtration and guides uniform water flow through the filter media.
2. Working Principle
- Water to be treated flows into the filter through the inlet. As it passes through the filter bag, impurities are trapped inside the bag, while clean water exits through the outlet via filter bag pores.
- When the filter bag is saturated with contaminants (judged by inlet-outlet pressure difference, e.g., >0.1MPa), the bag needs replacement without disassembling the entire system.
II. Main Types and Characteristics
1. Classification by Housing Type
Type Characteristics Application Scenarios Single-bag filter Contains only 1 filter bag, compact structure, small flow rate (5–50 m³/h), low cost. Small systems, laboratories, household water purification Multi-bag filter Can install 2–24 filter bags in parallel, large flow rate (up to 500 m³/h), requires manifold design. Industrial water treatment, municipal water supply (large systems) Top-inlet/side-inlet Different inlet positions; top-inlet ensures more uniform water flow, while side-inlet suits space-constrained scenarios. Selected based on installation space 2. Classification by Pressure Rating
- Low-pressure type: ≤0.3MPa, suitable for normal or low-pressure scenarios (e.g., municipal tap water filtration).
- Medium-high pressure type: 0.6–1.6MPa, ideal for high-pressure systems like industrial circulating water or RO pretreatment.
III. Advantages and Limitations
Advantages
- Flexible filtration precision: Can meet various needs from coarse to fine filtration by replacing filter bags of different precisions (1–500 microns).

How to select water filter bags suitable for specific water treatment needs?
Choosing the right water filter bags for specific water treatment requirements requires comprehensive consideration of water quality characteristics, treatment objectives, system parameters, and application scenarios. Below is a detailed selection process and key considerations:I. Clarify water quality and treatment objectives
1. Analyze water source impurity characteristics
- Particle types: Suspended solids (e.g., sediment, rust), colloids (e.g., clay, microorganisms), oils, or specific pollutants (e.g., metal ions, organic matter).
- Particle size: Determine the main impurity particle size range through water quality testing (e.g., coarse particles >50 microns, fine particles <10 microns).
- Chemical properties: Liquid acidity/alkalinity (pH value), corrosiveness (e.g., chloride ions, strong oxidizers), and temperature (normal or high-temperature environments).
2. Define filtration goals
- Precision requirements: Target filtration accuracy (e.g., drinking water ≤5 microns, industrial circulating water up to 50 microns).
- Treatment volume: Water flow rate per unit time (e.g., 10 m³/h, 100 m³/h), affecting filter bag size and quantity.
- Impurity interception capacity: Concentration of contaminants to be intercepted (high-turbidity water sources require high dirt-holding capacity filter bags).
II. Core selection parameters
1. Filtration precision (critical parameter)
- Precision range: Common filter bag precisions range from 1–500 microns, selected based on impurity particle size.Note: Excessively high precision may cause rapid clogging; balance filtration efficiency with flow rate.
- Examples:
- Swimming pool water filtration: 20–50 microns (removes hair, sediment).
- Pre-treatment for electronic-grade ultrapure water: 1–5 microns (intercepts tiny particles).
- Chemical wastewater oil removal: 10–25 microns (paired with demulsification processes).
- Examples:
2. Material compatibility
- Common materials and applications:
Material Corrosion resistance Temperature resistance Typical applications Polypropylene (PP) Resistant to acids, alkalis, salt solutions ≤80℃ Industrial wastewater, municipal sewage, food processing Polyester (PET) Resistant to oil and general solvents ≤120℃ Lubricating oil filtration, oily wastewater treatment Nylon (PA) Resistant to strong alkalis, wear-resistant ≤90℃ High-turbidity water sources, metalworking fluid filtration - Selection principles:
- Choose PP material for acidic liquids and PA or PET for alkaline liquids.
- Select PET or special high-temperature-resistant fibers for high-temperature environments (e.g., boiler water).
3. Filter bag size and structure
- Specification categories:
- No. 1 bag: Diameter 110mm, length 380mm, flow rate ~5–15 m³/h (common in small systems).
- No. 2 bag: Diameter 180mm, length 810mm, flow rate ~20–50 m³/h (mainstream for medium-to-large systems).
- Others: No. 3 bags, No. 4 bags, or non-standard custom sizes.
- Structural design:
- Monofilament filter cloth: Smooth surface, easy to clean, suitable for intercepting large particles (coarse filtration).
- Multifilament/needle-punched filter cloth: Deep filtration, high dirt-holding capacity, suitable for fine particle filtration.
- Reinforced ring design: Stainless steel or plastic rings at the top to prevent bag mouth tearing and improve pressure resistance.
4. Pressure resistance and flow matching
- System pressure: Filter bags must withstand ≥ system operating pressure (typically 0.1–0.6MPa); use thickened materials or metal frame supports for high-pressure scenarios.
- Flow calculation:
- A single No. 2 bag at 50-micron precision has a flow rate of ~30 m³/h; for a 100 m³/h system, parallel 4 bags (with redundancy).
III. Other key factors
1. Dirt-holding capacity and replacement cycle
- Dirt-holding capacity: Total amount of impurities a filter bag can retain (unit: g/bag); high capacity reduces replacement frequency.
- Estimation method:
- For known suspended solids concentration (e.g., 500 mg/L) and total treatment volume (e.g., 1000 m³), total impurity weight = 500 mg/L × 1000 m³ = 500 kg.
- If a single filter bag holds 5 kg, it needs to be replaced 100 times per cycle, or increase the number of filter bags to reduce frequency.
2. Environmental protection and cost
- Disposable vs. washable:Material recyclability: Prioritize recyclable PP/PET materials to reduce plastic pollution.
- Disposable filter bags: Low cost (~¥10–50/bag), suitable for complex impurities or non-washable scenarios.
- Washable filter bags: Higher cost (~¥200–500/bag) but reusable, ideal for high-value liquids or strict environmental requirements.
3. Compatibility with supporting equipment
- Filter type: Must match filter bag size (e.g., No. 1 bag for small filters, No. 2 bag for standard filters).
- Sealing method: O-ring or flange sealing to ensure no leakage.
IV. Selection process example
Scenario: A food factory needs to filter production water containing sediment (particle size 20–100 microns), with a flow rate of 50 m³/h and normal-temperature neutral water.- Precision selection: Intercept particles >20 microns, choose 25-micron precision filter bags.
- Material selection: Neutral water, choose economical and durable PP material.
- Size selection: Single No. 2 bag flow rate 30 m³/h, require 2 bags in parallel (total flow 60 m³/h to cover 50 m³/h demand).
- Structure selection: Needle-punched filter cloth (deep filtration, high dirt-holding capacity) with stainless steel reinforcing rings.
- Replacement cycle: Estimated daily treatment volume 400 m³, inlet suspended solids concentration 200 mg/L, daily impurity total 80 kg; single bag dirt-holding capacity 5 kg, requires daily replacement of 2 bags (or replace every 2 days with spare bags).
V. Notes
- Testing and verification: For high-requirement scenarios (e.g., pharmaceuticals, electronics), test with sample filter bags first to confirm filtration efficiency and service life.
- Supplier qualification: Choose ISO-certified manufacturers to ensure filter bags meet hygiene standards (e.g., food-grade requires FDA certification).
- Emergency plans: Stock spare filter bags to avoid system downtime; regularly inspect for damage (replace immediately if pressure drop surges).

The ACCU-PULSE DMF-Z-25 pulse valve
The DMF-Z-25 pulse valve is a right-angle electromagnetic pulse valve commonly used in the cleaning and injection systems of pulse-jet bag dust collectors, serving as a “switch” for compressed air. The detailed introduction is as follows:
The ACCU-PULSE DMF-Z-25 pulse valve Working Principle
The DMF-Z-25 pulse valve is a pilot-type solenoid valve. When energized, the electromagnetic force drives the pilot valve to open, rapidly reducing the pressure in the upper cavity of the main valve. A pressure difference is formed between the upper and lower cavities of the main valve, and the medium pressure pushes the closing member of the main valve upward, opening the valve and allowing compressed air to spray out through the valve outlet. When power is cut off, the spring force closes the pilot valve, and the inlet medium pressure quickly enters the upper cavity of the main valve through the pilot hole, forming a pressure difference in the upper cavity to close the main valve and stop the pulse valve from exhausting air.The ACCU-PULSE DMF-Z-25 pulse valve Technical Parameters

DMF-Z-2-20 ACCU-PULSE Working Principle
The diaphragm divides the electromagnetic pulse valve into front and rear air chambers. When compressed air is connected, it enters the rear air chamber through the orifice, and the pressure in the rear air chamber presses the diaphragm assembly tightly against the valve’s outlet, keeping the electromagnetic pulse valve in the “closed” state. When the pulse injection control instrument sends an electrical signal, the armature of the electromagnetic pulse valve moves backward, opening the rear air chamber and rapidly releasing pressure. The diaphragm assembly moves backward, allowing compressed air to spray out through the valve outlet, and the pulse valve enters the “open” state. When the electrical signal from the pulse injection control instrument disappears, the armature of the electromagnetic pulse valve resets, the exhaust port of the rear air chamber closes, the pressure in the rear air chamber rises, and the diaphragm assembly moves close to the valve’s outlet, re-closing the pulse valve.DMF-Z-2-20 ACCU-PULSE Technical Parameters

Electromagnetic Pulse Valves: Opening a New Era of Intelligent Industrial Cleaning
With the advent of the intelligent industrial era, electromagnetic pulse valves are also actively integrating into the intelligent wave and becoming a key part of realizing intelligent industrial cleaning.
Intelligent electromagnetic pulse valves are equipped with advanced sensors and intelligent control systems. These sensors can real – time monitor key parameters such as the resistance of the filter bag, dust concentration, and the operating status of the equipment. Take the large – scale dust removal system in a chemical enterprise as an example. The sensors transmit the collected data to the intelligent control system in real – time. The system analyzes and processes these data to accurately judge the ash – cleaning requirements of the filter bag. When the resistance of the filter bag reaches the set threshold, the intelligent control system automatically issues an instruction to control the electromagnetic pulse valve for ash – cleaning operation. Moreover, the system can automatically adjust the injection time, injection interval, and injection pressure of the electromagnetic pulse valve according to the actual situation to ensure the ash – cleaning effect while minimizing energy consumption.The intelligence of electromagnetic pulse valves is also reflected in remote monitoring and fault diagnosis functions. With the help of the Internet of Things technology, enterprise managers can remotely monitor the operating status of electromagnetic pulse valves at any time through terminal devices such as mobile phones and computers. Once a fault occurs in the equipment, the intelligent system can quickly issue an alarm and accurately locate the fault point through data analysis. For example, in the dust removal equipment of the mining industry, if a fault such as valve core jamming occurs in the electromagnetic pulse valve, the intelligent system will immediately notify the maintenance personnel and provide detailed fault information, greatly shortening the equipment maintenance time and improving production efficiency.The intelligent transformation of electromagnetic pulse valves has brought higher efficiency, lower costs, and more reliable operation guarantees for industrial cleaning. It has opened a new era of intelligent industrial cleaning, enabling industrial production to continuously move forward on the path of environmental protection and high – efficiency, laying a solid foundation for realizing a sustainable industrial future. -
Electromagnetic Pulse Valves: Key Equipment for Promoting the Upgrading of the Environmental Protection Industry
The environmental protection industry occupies an increasingly important position in today’s social development. As a key component of environmental protection equipment, electromagnetic pulse valves are promoting the technological upgrading and efficient development of the environmental protection industry.
Picture (DMF-Z-40S Pulse Valve)
Electromagnetic pulse valves have the significant advantage of fast response speed. In some production environments with extremely strict requirements for dust emissions, such as electronic chip manufacturing workshops, electromagnetic pulse valves can respond in a very short time. Once it is detected that the dust accumulation on the surface of the filter bag reaches a certain level, the control system issues an instruction, and the electromagnetic pulse valve can quickly open and complete a pulse injection action within a few milliseconds, timely removing the dust on the filter bag and ensuring that the air quality in the workshop always meets strict standards, providing a clean environment for precision production.
The energy – saving characteristics of electromagnetic pulse valves are also remarkable. The ash – cleaning methods of traditional dust removal equipment often consume a large amount of energy. Modern electromagnetic pulse valves, through optimized design, can precisely control the injection volume and injection time of compressed air. For example, in the small – scale dust removal system used in a food processing factory, the electromagnetic pulse valve adopts intelligent control technology. It automatically adjusts the injection parameters according to the actual working conditions of the filter bag. In this way, while meeting the ash – cleaning requirements, it greatly reduces the waste of compressed air, reducing the energy consumption and operating costs of enterprises.On the path of the environmental protection industry’s continuous pursuit of green and efficient development, the importance of electromagnetic pulse valves has become more prominent. It not only improves the performance and reliability of environmental protection equipment but also provides strong support for enterprises to achieve energy conservation, emission reduction, and sustainable development. With the increasingly strict environmental protection standards, electromagnetic pulse valves will have a broader development space and continue to contribute to the upgrading of the environmental protection industry. -
Electromagnetic Pulse Valves: The Core Power of Industrial Dust Removal Systems
In modern industrial production, dust pollution not only poses a threat to the environment but also seriously endangers the normal operation of production equipment and the health of workers. As a key component of industrial dust removal systems, electromagnetic pulse valves play an irreplaceable role.
The working principle of electromagnetic pulse valves is based on the law of electromagnetic induction. When the electromagnetic coil of an electromagnetic pulse valve is energized, the generated electromagnetic force overcomes the spring force, lifts the valve core, opens the gas passage, and allows compressed air to spray out rapidly. When the electromagnetic coil is de-energized, the electromagnetic force disappears, and the spring force makes the valve core return to its original position, closing the gas passage and stopping the gas injection. This rapid opening and closing action can precisely control the injection time and frequency of compressed air.In the field of industrial dust removal, electromagnetic pulse valves are widely used. Take a cement plant as an example. A large amount of dust is generated during the production process. In a bag filter, the electromagnetic pulse valve emits a pulse jet at regular intervals. The compressed air is sprayed into the interior of the filter bag at high speed. The strong air flow impact causes the filter bag to expand and vibrate instantaneously, shaking off the dust attached to the surface of the filter bag, thus achieving the ash cleaning of the filter bag. In this way, not only can the air permeability of the filter bag be ensured, the high – efficiency operation of the dust collector be maintained, but also the service life of the filter bag can be extended, reducing the operating costs of enterprises.In other industrial fields such as steel plants and thermal power plants, electromagnetic pulse valves also play an important role. They ensure a clean production environment, reduce the erosion of dust on equipment, and improve the safety and stability of production. With the continuous progress of industrial technology, electromagnetic pulse valves are also constantly innovating and developing, moving towards higher performance, more energy – saving, and more intelligent directions to meet the needs of future industrial development.
