Acid-Resistant High-Pressure Nanofiltration Membrane Products
Product Description
- Membrane material: Polypiperazine Amide Composite Membrane
- Membrane characteristics: Acid-resistant, high-pressure resistant
- Housing material: FRP (fiberglass reinforced plastic)
- Flow channel type: Parallel flow channel 34 mil / 46 mil, optional other sizes
- Application scenarios: Lithium extraction and concentration in new energy industry, magnesium-lithium separation, desalination in chlor-alkali denitrification, acid recovery from power plant wastewater, separation and purification of acidic materials, and concentration of acid-containing solutions.
Product Features
- Advanced Surface Engineering: We integrate premium imported membranes with proprietary modification techniques to neutralize surface micro-defects, significantly bolstering acid durability while harmonizing flux and rejection rates.
- Broad Acid Compatibility: Engineered for aggressive media, maintaining peak performance in Phosphoric acid (≤15%) as well as Hydrochloric and Sulfuric acids (≤10%).
- Chemically Inert Architecture: Every structural component is specifically curated to ensure long-term stability in ultra-low pH environments.
- High-Efficiency Geometry: The implementation of multi-leaf, short-page welding optimizes the active filtration area, eliminating stagnant flow zones and maximizing permeate throughput.
- High-Pressure Sealing Integrity: A specialized acid-resistant potting compound prevents bypass at the element's stress points, securing consistent retention under rigorous pressure conditions.

FAQ
Q: What is the benefit of the Polypiperazine Amide material in this NF membrane?
A: Polypiperazine amide is a specialized composite material that offers high selectivity for multivalent ions (like Magnesium and Sulfate) while remaining stable under pressure. Combined with our proprietary surface modification, we eliminate the micro-defects common in standard films, ensuring the membrane doesn't degrade when exposed to harsh acidic feed streams.
Q: What are the exact chemical limits for this "Acid-Resistant" series?
A: These membranes are engineered for extreme pH environments. They can operate reliably in Phosphoric acid ($H_3PO_4$) up to 15% and Hydrochloric ($HCl$) or Sulfuric acid ($H_2SO_4$) concentrations up to 10%. Every component, from the membrane sheet to the internal spacers, is verified for low pH stability.
