Acid Resistant Spiral-wound Membrane

 Products of HA Series could achieve the concentration of metals from acid solution that contains sulfuric acid of less than 20% and phosphoric acid of less than 30%, as well as the purification of acid liquor. The membrane element could maintain high-flux and stable operation for more than 12 months in strong acid conditions.
