Easy-Cleaning Security Filter

The Easy-Cleaning Security Filter is a device used to remove fine particles from the liquid. It consists of a stainless steel shell and a filter element. The liquid flows in from the outside, passes through the filter element, and then flows out from the inside. During this process, the impurity particles in the liquid are trapped on the outside of the filter element, thus achieving the purpose of filtration and purification.

 

The easy-cleaning security filters are mainly used after multi-media pretreatment filtration and before membrane filtration equipment such as reverse osmosis and ultrafiltration. Its main function is to filter out fine substances after multi-media filtration to ensure water quality filtration accuracy and protect membrane filter elements from damage to large particulate matter. According to different usage occasions, different filtration accuracy can be selected to ensure the accuracy of the post-effluent and ensure the safety of the post-stage membrane elements.

 

The working principle of the security filter is to use the molded filter material. Under the action of pressure, the stock solution passes through the filter material, the filter residue remains on the pipe wall, and the filtrate flows out through the filter material, so as to achieve the purpose of filtration. This filtration method is simple and effective, and can effectively remove impurities in the liquid and improve the purity of the liquid.

 

Structure composition

The easy-cleaning security filter is usually composed of the following components:

1. Stainless steel shell. As the support structure of the entire filter, it provides sufficient strength and is easy to install and disassemble.

2. Filter element. The core component of a security filter, usually made of polypropylene, nylon, stainless steel, and other materials, with different pore sizes and filtration accuracy to meet the needs of different occasions.

3. Sealing ring. To ensure the sealing between the filter element and the shell, to prevent liquid bypass.

4. Import and export flanges. Connect pipes to guide liquids into and out of the filter.

Application field

The easy-cleaning security filters are widely used in the following fields:

1. Drinking water treatment. Remove fine impurities from water to improve the quality of drinking water.

2. Industrial water treatment. In the electronics, pharmaceutical, food, chemical, and other industries, process water is deeply filtered.

3. Environmental engineering. In the wastewater treatment process, it is used to remove suspended solids and reduce pollutant emissions.

4. Seawater desalination. In seawater desalination pretreatment, security filters are used to remove fine suspended solids and colloids from seawater.

 

Operation

1. Installation. Install the filter element and shell correctly according to the instructions, ensure that the sealing ring is in good condition, and connect the inlet and outlet flanges.

2. Start. Slowly open the water inlet valve to allow the liquid to enter the filter and check for leakage.

3. Operation. Adjust the operating parameters of the system, such as pressure, flow, etc., to achieve the best filtration effect.

4. Monitoring. Regularly check the quality of the effluent to ensure that the filtration effect is stable.

 

Maintenance

1. Cleaning. When the pressure difference between the inlet and outlet of the filter is too large, the filter element needs to be cleaned. Backwashing, chemical cleaning and other methods can be used.

2. Replacement. When the filter element service cycle reaches or the filtration effect is still not up to standard after multiple cleanings, a new filter element should be replaced.

3. Safety measures. During operation and maintenance, relevant safety regulations should be followed to ensure the safety of personnel and equipment.

 

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.
