Water Treatment Use Stainless Steel Duplex Filter

Water filtration is one of the important links to ensure the safety of drinking water, improve the quality of industrial water and protect the environment. Among many water treatment technologies, the stainless steel duplex filter, as an efficient and practical pretreatment equipment, is widely used in water treatment systems in household, commercial and industrial fields. It works together through two parallel filter units, which not only improves the filtration efficiency, but also ensures the reliability of continuous water supply.

The Water Treatment Use Stainless Steel Duplex Filter plays an important role in ensuring water quality safety and improving water quality due to its high efficiency, flexibility and reliability.

The core design concept of this type of filter is to "prepare one for use" or "work at the same time and share the load". The two filter units are usually equipped with the same or different grades of filter cartridges, and are designed to work in series or parallel according to actual needs. In the series mode, the raw water is first removed by the first filter to remove large particles of impurities, and then enters the second filter for further purification to achieve higher-level water quality requirements. In the parallel mode, the water flow is equally divided into two channels and passes through two filters at the same time, which is suitable for scenarios that require high flow or fast filtration, effectively dispersing the filtration pressure and prolonging the service life of the equipment.

Specifications

Structure composition

The Water Treatment Use Stainless Steel Duplex Filter is mainly composed of the following components:

1. Shell

Usually made of stainless steel to ensure corrosion resistance and structural strength, it is the main body that houses the filter element.

2. Filter element

According to the filtration requirements, filter elements of different materials and pore sizes, such as PP cotton, activated carbon, ceramics, resins, etc., are used to intercept different sizes of suspended solids, organic matter, residual chlorine, etc.

3. Valve assembly

Including water inlet valve, water outlet valve, bypass valve and sewage valve, etc., used to control the direction of water flow, switch the working state of the filter and clean sewage operations.

4. Pressure gauge

Monitor the water pressure difference before and after filtration, indirectly reflect the degree of clogging of the filter element, and guide when to replace or clean the filter element.

5. Bracket or mounting base

Ensure that the equipment is firmly installed for easy operation and maintenance.

Application field

1. Household water. As a pre-filter device, it protects household water purifiers, water heaters, washing machines and other wading appliances from impurities and improves water quality.

2. Commercial venues. Hotels, restaurants, cafes, etc., to ensure the cleanliness of drinking water and food processing water.

3. Industrial water use. In the chemical, electronics, pharmaceutical and other industries, it is used as a primary filtration to protect precision equipment and reduce the impact of scale and impurities on the production process.

4. Cooling circulation system. Protect the pipes and equipment of cooling towers, central air conditioning and other systems to prevent scale and dirt deposition.

Maintenance

1. Periodic inspection. Observe the pressure gauge reading. When the pressure difference reaches a certain value (usually 1.5 times the initial pressure difference), it indicates that the filter element is blocked and needs to be cleaned or replaced in time.

2. Cleaning and replacement. According to the frequency of use and water quality, regularly remove the filter element for cleaning or directly replace the new filter element. Pay attention to choosing the appropriate cleaning method according to the filter element type.

3. Valve operation. When switching filters or performing maintenance, operate the valve correctly to avoid waterway interruption or system damage due to misoperation.

4. Antifreeze and keep warm. In cold regions, thermal insulation measures should be taken in winter to prevent damage caused by freezing water in the shell.

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.
