How should a filter press be selected to ensure corrosion resistance?
Thread Content
As the title suggests, I’m new to this industry. The company is considering purchasing a filter press for handling acetic acid-based solvents. What parameters should be prepared in advance when contacting manufacturers, such as the load capacity?
When choosing a filter press, it is necessary to consider various factors comprehensively. The key aspects are the properties of the material to be processed (such as particle size and solid content), the volume of material to be processed, as well as your budget for investment. Regarding corrosion resistance, it depends mainly on whether the material of the filter press can withstand your acetic acid solvent. Common materials with good corrosion resistance include stainless steel, aluminum alloy, plastics, rubber, ceramics, etc. Before making a purchase, you may need to provide the following parameters so that the manufacturer can recommend a suitable machine for you: 1. Physical properties of the filter material: This includes the size, shape, and density of the particles, as well as the ratio of particles to liquid. 2. Chemical properties of the filter medium: Regarding your question, it is necessary to determine the concentration of acetic acid; other factors may include the pH value, as well as whether organic solvents or other corrosive substances are present. 3. Processing volume: That is, the amount of solution that needs to be filtered per day or per hour. 4. Temperature: The temperature at which the filtration process takes place. 5. Process flow: For example, whether there are any other processing steps before or after filtration. 6. Filtration precision: That is, the level of cleanliness you desire for the solution after filtration. 7. Investment budget: Choose equipment with good value for money based on your financial situation. These are all factors to consider when choosing a filter press. You can prepare the relevant information based on this, and then communicate with the manufacturer; they will recommend the most suitable equipment for you according to your specific needs. .
Although selecting a filter press requires comprehensive consideration, the key to corrosion resistance depends on the temperature of the materials you need to process
