The HA series products can achieve metal concentration in acidic solutions such as sulfuric acid less than 20% and phosphoric acid less than 30%, and can also be used for acid purification. Membrane elements maintain high flux in a strong acid environment and operate stably for more than 12 months.

 

 

Industry application

 

● Steel cold-rolled pickling water is fully reused
