4 Procedures for Analyzing the Fouling Layer Structure During a Membrane Filtration Process 

The iteration is repeated until the value of the calculated hydraulic pressure in each layer matches the pre-obtained hydraulic pressure distribution. 

For each time increment (t t2), the above-proposed iteration procedure is repeated until the calculated total pressure drop through the entire fouling layer is equal to the applying pressure. By substituting the new profile of porosity of the fouling layer into Equation (15.10), the value of local specific filtration resistance for each control mass of the fouling layer can be obtained. 

Steps 3 and 4 are repeated continuously during a membrane filtration process, thus the variation of the fouling layer properties can be monitored for the entire
