The selection of filter elements suitable for industrial sewage treatment needs to consider the following key factors:

1. Sewage characteristics

- Analyze the type, concentration, particle size and shape of pollutants in sewage. For example, for sewage containing a large number of large particle impurities, it may be necessary to select a filter element with a larger aperture; For sewage containing small particles and colloidal substances, a more accurate filter element is required.

- Understand the pH, temperature and chemical corrosion of the sewage to choose the filter material that can withstand the corresponding conditions.

2. Filtration accuracy requirements

- Determine the required filtration accuracy according to the water quality standard after treatment. High-precision filters can remove finer impurities, but can lead to faster clogging and higher operating costs; The lower precision filter element may not meet the processing requirements.

3. Filter material

- Common materials include polypropylene (PP), polyester (PET), stainless steel, ceramics, etc. PP filter element cost is low, suitable for general filtration; Stainless steel filter element has strong corrosion resistance, suitable for harsh environment; Ceramic filter element has high strength and high temperature resistance.

- The chemical stability of the material should match the chemical properties of the sewage to prevent corrosion or damage to the filter element.

4. Contaminant capacity

Selecting a filter element with a large contaminant capacity can reduce the frequency of replacement, reduce operating costs and maintenance workload.

5. Ability to withstand pressure

- Consider the pressure situation in the sewage treatment system to ensure that the filter element can withstand the corresponding pressure without deformation or damage.

6. Traffic requirements

- According to the needs of the treated water volume and flow rate, select the filter element specifications that can meet the flow requirements to ensure the treatment efficiency.

7. Cost effectiveness

- Consider the price, service life and replacement frequency of the filter element to evaluate its long-term cost-effectiveness.

8. Supplier reputation and after-sales service

- Choose suppliers with good reputation and perfect after-sales service in order to obtain technical support and problem solving during use.

In short, in the selection of industrial sewage treatment filter, it is necessary to fully combine the actual sewage situation, treatment requirements and economic budget and other factors, a comprehensive balance and comparison, in order to select the most suitable filter.
