Operating data 

– this is where the 

operating flux is determined

(1) Clean water flux before chemical 

cleaning

Pure water counter pressure cleaning

(2) Measurement of flux

Cleaning with mixed chemical solution

(3) Measurement of flux

Cleaning with sodium hypochlorite 

water solution

(4) Measurement of flux

(2) ≥ 90% of operating flux

(3) ≥ 90% of operating flux

(4) ≥ 90% of operating flux

Figure 1.

 By measuring the flux between each cleaning step, it is easy to determine if further or more intense 

cleaning is necessary in order to restore membrane performance.
