How is the filtration area of a PET filter designed? Could everyone give an answer? What is the relationship between filtration precision and filtration area? How to determine it?
Let’s talk about the general principles of filter design. Generally, it is necessary to first obtain the filtration constant qe and the K value based on empirical data (or by conducting necessary experiments if no such data are available). Based on the filter volume V and filtration time T specified in the design requirements, an appropriate pressure drop is selected to determine the filtration area. The calculation formulas are also divided into two types according to the specific form of filtration: constant-rate filtration and constant-pressure filtration, each with its own corresponding formula. For detailed information, it is recommended to refer to the Tianjin University edition of \"Principles of Chemical Engineering\".
The finer the filtration precision, the larger the filtration area required to handle a given flow rate of liquid; specifically, it depends on the type of filter material chosen to determine the design requirements
