Filter Properties
A well-designed process filtration system produces the greatest volume of finished product for the lowest operating cost. Achieving this goal requires that you select the filter whose properties best meet the demands of your application. Filter selection is a complex process based on the following questions:
- What is the process stream to be filtered?
- Size and nature of the particles or molecules to be removed
- Chemical composition
- Temperature
- Viscosity
- Size and nature of the particles or molecules to be removed
- What pore size or nominal molecular weight rating (NMWL) is required to achieve separation?
- Will this be a sterilizing filtration?
- What is the desired flow rate? Or, what is the batch size and available processing time?
- What is the available line pressure and maximum available filter differential pressure?
- What plumbing connections are required?
