High Quality Security Filter

A high quality security filter, also known as a precision filter, is a high-efficiency water treatment device that is mainly used to remove fine particulate matter from water to protect subsequent water treatment equipment from contamination and damage.

 

Definition and function

--- Definition

The high quality security filter is responsible for the link in the water treatment system located at the end of the pretreatment stage and before the membrane treatment. Its main function is to capture and remove suspended solids in the water, such as sediment, colloids, algae debris, microorganisms, and filter debris that has not been completely removed during the pretreatment stage.

--- Function

Protect subsequent equipment, ensure water quality entering precision membrane modules such as reverse osmosis, nanofiltration, and ultrafiltration, reduce membrane surface contamination, and prolong membrane module life.

 

Equipment features

1. High filtration accuracy. The filter element has a uniform pore size, which can effectively remove fine particulate matter from the water.

2. Small filtration resistance. Large flux, strong pollution interception ability, and long service life.

3. Excellent material. The shell of the cylinder is generally made of stainless steel, and the filter element material has high cleanliness and no pollution to the filter medium.

4. Chemical corrosion resistance. Acid, alkali and other chemical solvents, high strength, high temperature resistance, filter element is not easy to deform.

5. Economical and practical. Low price, low operating cost, easy to clean, and replaceable filter element.

 

Application field

The high quality security filters are widely used in the following fields:

1. Pharmaceutical, food, chemical, environmental protection, water treatment and other industrial fields.

2. Nanofiltration (NF), ultrafiltration (UF), reverse osmosis (RO), electrodialysis (EDI) and other system security filtration and end point filtration.

3. Medical injection, large infusion, eye drops, Chinese herbal medicine liquid filtration, biological preparation extraction, purification, concentration.

4. Electronics, microelectronics, semiconductor industry with high-purity water pre-filtration, end point filtration.

5. Drink purified water, mineral water, fruit juice, tea drinks, health drinks filter treatment.

6. Baijiu, wine, beer, rice wine and other fruit wine filtration.

7. Pretreatment filtration or security filtration in the process of production, domestic wastewater treatment and reuse of wastewater.

 

Parameters

Composition

1. Filter shell

- Material. It is made of 304 stainless steel. For special occasions such as acid and alkali resistance, 316 stainless steel can be used as the shell.

- Type. It can be divided into flange type and clamp type. Flanged shell is mainly used in large filtration flow occasions.

- Connection method. The inlet and outlet are generally flanged to ensure sealing and easy installation.

2. Filter element

- Material. The filter element is the core component of the security filter, responsible for filtering impurities, suspended solids and other pollutants in the water. The filter element materials mainly include sintered filter tubes, meltblown fiber filter elements (such as polypropylene PP filter elements), and honeycomb filter elements.

- Type. Mainly PP filter cotton. Wire wound filter elements or activated carbon filter elements can also be used in some occasions.

- Installation. The number of filter elements installed can range from one to dozens, mainly depending on the size of the processing capacity.

3. Seals. Ensure that the filter does not leak under high pressure.

4. Brackets and fasteners. Used to fix and install filters.

 

Ways to extend the lifespan of equipment

1. Regularly clean and maintain the filter to remove dirt, sediment, and particles from the filter surface in time to prevent clogging and ensure the normal operation of the filter.

2. Take appropriate water treatment measures, such as installing pretreatment equipment, to reduce the burden on security filters.

3. Avoid overloading the filter, that is, exceeding its designed capacity. Overloading may cause the filter to overload and affect its service life.

4. Install the filter correctly, ensuring that the installation meets the manufacturer's guidelines to avoid incorrect pipe connections or external damage to the filter.

5. Regularly check the performance and status of the filter to detect problems and take necessary maintenance measures.

 

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.
