Long Service Life Security Filter

The long service life security filter removes impurities such as fine particles, suspended solids, colloids, etc. from liquids, usually installed before reverse osmosis membrane filtration to protect downstream precision equipment and the environment from contamination. It works based on mechanical filtration, which uses the specific pore size distribution of the filter element to intercept impurities.

Working principle

The core working principle of the long service life security filter is based on the physical interception mechanism. It uses polypropylene (PP) meltblown filter cartridges, wire wound filter cartridges or folded filter cartridges as the filter medium. These filter cartridges are covered with tiny pores. When the water flows, impurities larger than the pore size are trapped on the surface or inside of the filter cartridge, while the purer water continues to flow through the filter cartridge to the next processing step. Over time, impurities gradually accumulate on the surface and inside of the filter cartridge, resulting in increased filtration resistance. At this time, the filter cartridge needs to be cleaned or replaced.

Parameters

Structure composition

The main structure of a long service life security filter typically includes the following components:

- Shell. Made of high-quality stainless steel to ensure corrosion resistance and durability, providing a solid support for the filter cartridge.

- Filter cartridge. As the core of filtration, PP meltblown filter cartridges, wire wound filter cartridges, folding filter cartridges, etc. are commonly used. Filter cartridges of different materials and precision are selected according to different filtration requirements.

- Seals. Such as sealing rings, used to ensure the sealing between the shell and the filter element, and between the inlet and outlet, to prevent water leakage.

- Inlet and Outlet. The design has a clear principle of high input and low output to ensure that the outside of the filter cartridge enters the water and the inside exits the water to optimize the filtration effect.

Application field

The long service life security filter is widely used in many industries due to their high efficiency and cost-effectiveness.

- Drinking water treatment. To ensure the safety of household and public drinking water, security filters are an indispensable part of pre-treatment.

- Industrial wastewater treatment. In the industrial production process, security filters can effectively intercept suspended solids and protect subsequent advanced treatment equipment.

- Cooling circulating water system. Avoid impurity deposition in circulating water and protect cooling equipment from wear.

- Semiconductor Manufacturing. In the semiconductor industry where high-purity water is required, security filters are an important pretreatment step before the preparation of ultrapure water.

- Power industry. Such as chemical water treatment in thermal power plants, to ensure the quality of boiler feed water and prolong the life of equipment.

Maintenance

Maintenance is the key to ensuring the long-term stable operation of security filters.

- Regular cleaning. According to the actual usage, the filter element is cleaned regularly to restore the filtration performance.

- Filter element replacement. When the filtration resistance increases to affect the system efficiency or reaches the manufacturer's recommended replacement cycle, the filter element should be replaced in time.

- Seal inspection. Regularly check the housing seals, and replace them immediately if bulging or wear is found.

- Monitor the pressure difference. Use a pressure gauge to monitor the pressure difference between the inlet and outlet water as the basis for judging the degree of clogging of the filter element.

- Shell cleaning. Keep the outside of the shell clean to prevent dirt accumulation from affecting the overall hygiene conditions.

FAQ

1. Q: What is the function of a filter?

A: The main function of a filter is to remove solid particles, impurities, and harmful substances from liquids or gases, in order to achieve purification, clarification, and protection of equipment.

2. Q: How to choose a suitable filter?

A: When choosing a filter, factors such as the properties of the material being filtered (e.g., viscosity, temperature, corrosion), required filtration accuracy, processing capacity, operating pressure and medium, as well as the type, material, size, and installation method of the filter should be considered.

3. Q: What is the working principle of a filter?

A: The working principle of a filter mainly relies on physical screening, deep interception, absorption, or chemical reactions to remove impurities or harmful components from the material being filtered.

4. Q: How to maintain and care for a filter?

A: Maintenance of filters includes regular cleaning or replacement of filter elements, inspection of seals and fasteners, maintaining stable operating pressure, and avoiding overloading. Specific methods should be referenced from the filter's instruction manual and maintenance guides.

5. Q: What is the service life of a filter?

A: The service life of a filter depends on its working environment, processing volume, and filtration accuracy. Generally, when the filter's pressure drop reaches a certain value or the filtration effect decreases significantly, it needs to be replaced or cleaned.

6. Q: What should be paid attention to during filter installation?

A: During filter installation, attention should be paid to the directionality, ensuring that the fluid enters and exits from the correct ports. Also, the piping system should be cleaned before installation, and the filter should be securely fastened and sealed as required by the instructions.

7. Q: What is the replacement cycle for filters?

A: The replacement cycle for filters depends on their working conditions and filtration requirements, and is usually indicated by pressure difference indicators or timers. When the filter's pressure drop reaches the set value or the filtration effect decreases, it should be replaced in a timely manner.
