HFU  series  provides  high  integrity  and  durability  under  recommended 

operating conditions. 

(4)  High Chemical Durability 

The membrane material of HFU series is PVDF, which allows you to clean 

the  membrane  with  high  concentrations  of  chlorine  and  with  high 

concentrations  of  acid  resulting  in  better  cleaning  and  longer  sustainable 

membrane flux rates. 

2.
