Calculation of membrane processes

We have compiled some very useful calculation formulas with which entire membrane processes can be estimated and optimized from a few test results. In the following 2 documents these are discussed and the application shown by examples

1. Calculation formulas for pressure-driven membrane processes

Calculation of a concentration as batch or continuous process. Calculation of product yield, concentration of total permeate, influence of concentration factor on product yield. Diafiltration

Membrane process calculations

2. Washing out - diafiltration

Comparison of the alternating concentration and re-dilution for washing out a component against diafiltration at a constant level
